Providing Out-of-Band Connectivity to Mission-Critical IT Resources

SD-WAN Benefits: Your Definitive Guide

Illustration of a variety of devices connected to a complex enterprise WAN that needs SD-WAN benefits like centralized orchestration and enhanced security.
SD-WAN, or software-defined wide area networking, is on the rise as organizations grow more distributed and networks get more complicated. SD-WAN’s market share was an estimated $3.4 billion in 2022 and is predicted to increase to $13.7 billion by 2027. Orgs leverage SD-WAN to reduce MPLS costs, improve WAN performance, facilitate greater automation and orchestration capabilities, and improve their security posture. This post explains how SD-WAN works in addition to its benefits.

How does SD-WAN work?

SD-WAN uses software abstraction to decouple WAN control functions from the underlying hardware. When possible, it leverages traditional MPLS to handle requests for enterprise resources in the data center, but it can also use less-expensive cellular and public internet links to handle cloud-destined traffic. SD-WAN uses virtualized and cloud-based security technologies to securely connect remote sites to SaaS, web, and cloud resources, reducing MPLS bandwidth and eliminating the need for VPNs.

SDWan Gateway
Organizations install SD-WAN gateways at campuses, branches, data centers, and any other business locations accessing the WAN architecture. These gateways virtualize WAN management at their sites, giving admins control via centralized software (which is often cloud-based).

Regional points-of-presence (PoPs) act as SD-WAN gateways for employees working from home, giving them access to enterprise network resources without a VPN. Often, major SD-WAN providers have an existing network of regional PoPs to take advantage of, but large or especially geographically diverse organizations may also wish to deploy their own PoPs in specific areas.

There are several different SD-WAN deployment architectures for companies to choose from depending on their specific requirements and capabilities. Learn more in A Guide to SD-WAN Deployment Models.

SD-WAN benefits guide

SD-WAN benefits organizations with complex and highly-distributed networks in the following ways:

SD-WAN Benefits

Reduces costs

  • MPLS bandwidth reduction
  • Fewer circuit installations
  • Faster branch deployments

Improves performance

  • Fewer data center bottlenecks
  • Faster issue response
  • Holistic performance monitoring

Enables automation & orchestration

  • Automated configurations
  • Policy-based workflow automation
  • Centralized orchestration

Enhances branch security capabilities

  • On-ramp to SSE technology
  • Enterprise policy extension
  • Secure access for remote users

SD-WAN reduces costs

MPLS bandwidth is far more expensive than standard broadband, fiber, or cellular, often hundreds of dollars per megabit per month. For branches with existing MPLS circuits installed, SD-WAN reduces bandwidth costs by redirecting traffic that’s destined for the cloud or internet across less-expensive channels, reserving the MPLS for enterprise traffic alone.

For some branch networking use cases, such as IoT (internet of things) deployments relying entirely on cloud-based software and data processing, organizations may opt to forgo a new MPLS installation and rely solely on SD-WAN and cloud-based security solutions. Not only does this save money on installation costs and bandwidth, but it significantly reduces the time it takes to spin up a new branch, enabling that branch to generate revenue sooner.

SD-WAN improves performance

SD-WAN uses technologies like application awareness and guaranteed minimum bandwidth to provide efficient, intelligent routing for improved performance. For example, in organizations with SASE (secure access service edge) deployments, SD-WAN automatically separates cloud- and SaaS-destined traffic to flow through the cloud-based SASE stack instead of the central firewall. This reduces the load on the firewall and ensures improved performance for users who do need to access enterprise resources, while at the same time providing a “shortcut” for remote users trying to reach the cloud.

SD-WAN also responds to availability and performance issues much faster than human admins are capable of, automatically redirecting traffic to avoid bottlenecks or downed nodes to ensure a seamless end-user experience. In addition, SD-WAN’s software abstraction makes it easier to centralize WAN management, giving admins full visibility into every part of the WAN architecture for holistic performance monitoring.

SD-WAN enables automation & orchestration

SD-WAN’s software abstraction opens up many automation opportunities because WAN configurations and workflows are no longer tied to the underlying hardware. For example, device, system, and service configurations can be written as scripts or playbooks and deployed automatically to reduce the time and effort required to spin up a new branch. Policy-based automation can handle additional tasks such as load balancing and failover, and route automation faster and more efficiently than human beings can.

SD-WAN also makes it possible to bring the WAN under one management platform for holistic monitoring and centralized orchestration. This gives admins control over large, distributed, and complex WAN architectures. For example, a centralized SD-WAN platform makes it easier to orchestrate traffic across hybrid cloud architectures because admins can monitor and manage WAN workflows across their various branches, private clouds, and public clouds.

SD-WAN automation and orchestration reduce the number of tedious, manual workflows that fall on overworked networking teams. This helps to decrease the rate of human error in device and security configurations, which in turn decreases the risk that mistakes will cause outages or be exploited by cybercriminals. Centralized SD-WAN orchestration also helps organizations improve their security posture by providing more holistic visibility into things like patch statuses, system changes, and traffic patterns.

SD-WAN enhances branch security capabilities

Another way SD-WAN improves network security is by making it easier to enforce security policies at branches and edge sites without deploying additional hardware or backhauling traffic through a central firewall. Since the SD-WAN control plane is decoupled from the underlying WAN hardware, organizations can also deploy advanced security technologies with fewer device compatibility issues.

SD-WAN enables organizations to use cloud-based security solutions like SSE (security service edge). SD-WAN’s intelligent, application-aware routing can automatically separate traffic from branches and other remote sites based on whether it’s destined for enterprise data center resources or resources that live in the cloud. Cloud-destined traffic is then diverted through the SSE stack, bypassing the main firewall and reducing bottlenecks at the data center.

SSE’s security stack typically includes Firewall-as-a-Service (FWaaS) technology which provides the same (or better) capabilities as a hardware appliance. SSE is also used to extend enterprise security and access control policies to traffic between remote sites and the cloud.

In addition, the SSE stack supports Zero Trust Network Access (ZTNA), which provides secure remote access to enterprise and cloud resources to WFH employees and other systems outside the WAN. In this way, ZTNA is similar to a VPN, only more secure. ZTNA only lets remote users see and interact with one specific resource at a time, and makes them re-authenticate if they wish to access something else. If a remote user account is compromised, this re-authentication step increases the chances that unusual behavior or failed multi-factor authentication (MFA) attempts will trigger an account lock, decreasing the blast radius of an attack.

When SD-WAN and SSE are married together under a single orchestration platform, the result is SASE (secure access service edge). Organizations can purchase a complete SASE solution, or use a vendor-neutral platform to combine the SD-WAN and SSE solutions of their choice for greater customization.

Simplifying Retail Network Management

Retail network management is visualized with interconnecting icons of networked retail services displayed in front of a retail warehouse

Fast and reliable networks are critical to the success of retail operations. Without network access, stores can’t process payments, handle customer data, or update inventory, which makes outages highly disruptive. According to a recent study, downtime could cost over $300,000 per hour in lost business, which is why it’s crucial that admins have the necessary tools to effectively monitor, manage, and optimize retail networks. This blog discusses some of the specific challenges involved in retail network management and how the right edge gateway solution can help overcome these difficulties.

Retail network management challenges

Managing a retail network comes with unique challenges, especially as the size and geographical distribution of the organization grows. Examples of these challenges include:

  1. Extending fast, reliable connectivity to the entire store for payment processing machines, inventory scanners, and other crucial devices. This is especially challenging in big box stores and other locations with large footprints as well as service-based chains with mechanics’ bays, drive-thrus, and other outdoor or semi-outdoor devices.
    .
  2. Maintaining optimal environmental conditions for networking equipment that’s often installed in closets, storage rooms, warehouses, and other out-of-the-way locations. The priority is typically to keep these devices hidden from customers, so they’re kept in areas that may not be climate controlled and may not have staff physically checking them every day. This increases the risk of environmental issues (like heat and humidity) causing a device failure and means no one is likely to notice the issue until it’s too late.
    .
  3. Remotely troubleshooting and recovering from issues without any on-site technicians. If the ISP connection, WAN, or LAN go down, there’s often no way to remotely access on-site equipment to diagnose and fix the problem. That means network outages require truck rolls to solve, with stores losing money waiting for technicians to travel on-site.
    .
  4. Efficiently monitoring and managing a distributed retail network architecture made up of many different network solutions and platforms. The lack of centralized management increases the risk of human error and makes it difficult to preemptively address potential problems or optimize the speed and performance of the network.

Retail network management teams need a robust solution that addresses these particular challenges. For example, they need small and powerful network devices that use centralized management to reduce management complexity. They also need a way to monitor environmental conditions and recover from outages without having to be on-site.

Simplifying retail network management

Now, let’s discuss how a robust branch gateway solution can help organizations address these challenges.

Compact, all-in-one networking

The layout of a retail store is carefully planned to ensure an optimal experience for customers, which means networking devices need to be as unobtrusive as possible. The ideal branch gateway for retail is compact and combines multiple networking functions, reducing the number of devices that need to be installed. Retail notoriously operates on a small profit margin, so the branch gateway also needs to be affordable without sacrificing performance.

Environmental monitoring

Environmental monitoring sensors collect data on conditions like temperature, humidity, and air quality in the location where networking equipment is installed. These sensors typically connect to the retail branch gateway via USB and report back to the management platform, giving admins the ability to remotely monitor the environment. This is crucial when most retail networks are managed by admins in a centralized office which may be hundreds or thousands of miles away from the stores themselves. Environmental monitoring allows them to identify and resolve potential problems before they cause device failures and outages. For example, if environmental sensors detect high temperatures, admins can get on-site personnel to turn up the air conditioning or call in an HVAC repair before devices overheat and bring down the network.

Out-of-band (OOB) management

Out-of-band (OOB) management uses redundant network interfaces (often cellular) to provide an alternative path to remote infrastructure. A branch gateway with OOB allows admins to remotely connect to devices in the store without relying on an IP address from the LAN, which means they’ll always have access even if the production network goes down. Without OOB management, the retail location goes offline for hours or even days waiting for a technician to arrive on-site, diagnose, and repair the issue. With OOB, admins can remotely access the infrastructure to restore services, often so fast that customers don’t even notice. That means they can remotely recover from more outages without truck rolls, saving time and money.

Vendor-neutral orchestration

A vendor-neutral branch gateway can interface with all the other devices in a retail network infrastructure, even if they’re from a different vendor’s ecosystem. This gives admins a single platform from which to monitor and manage every device in the store. Even better is when all of the branch gateways in the entire retail network architecture hook into a single, centralized, cloud-based orchestration platform. Admins can then monitor, control, and optimize network infrastructure for all the retail locations from one place for ultimate efficiency.

In addition, a vendor-neutral retail network management platform enables the use of third-party automation solutions. Automation reduces the risk of human error and makes it easier for teams to effectively manage and optimize even complex retail network architectures.

Retail network management with Nodegrid

Compact, all-in-one branch gateways like Nodegrid use environmental monitoring, OOB management, and vendor-neutral platforms to simplify retail network management. The Nodegrid Mini SR, for example, is an inexpensive retail branch gateway that’s roughly the size of an iPhone, so you can easily deploy them anywhere in your store without disrupting the customer experience. Despite its small size and low price point, the MSR still delivers Gen 3 OOB management capabilities while supporting Nodegrid environmental monitoring sensors and third-party automation. The Nodegrid platform is also completely vendor-neutral, giving retail network admins a single pane of glass from which to monitor, orchestrate, and optimize the entire distributed network architecture.

Network Automation Tools To Offset the Tech Talent Shortage

network automation tools
As enterprise networks grow more complex, there’s a rising need for highly-specialized engineers to implement and maintain these complicated architectures. However, due to the Covid-19 pandemic, a global recession, and other world events beyond an organization’s control, it can be very difficult to recruit and retain these specialists. In fact, many companies are currently relying on smaller IT teams than usual to manage their vital network infrastructure. According to Gartner research, the tech talent shortage is one of the biggest barriers to the adoption of emerging technology like network automation.

However, network automation tools can actually help understaffed organizations ensure the continued availability and performance of enterprise networks by streamlining workflows and reducing manual intervention. In this blog, we’ll discuss how four different types of network automation tools can be used to solve major problems caused by the tech talent shortage.

Problem Solution
You lack the staff required to efficiently deploy, monitor, and manage network configurations. Automated network configuration management solutions like SolarWinds Network Configuration Manager (NCM) and Micro Focus Network Automation Software.
You need to extend DevOps automation to networking without purchasing additional solutions or hiring network automation experts. DevOps configuration management solutions that can be used for server and network automation like RedHat Ansible and Puppet.
You want to improve network reliability and performance while reducing management complexity. Software-defined networking (SDN) and software-defined wide area networking (SD-WAN) solutions like Palo Alto Prisma and Cisco Meraki.
You lack full-coverage network security, so you’re unsure where your vulnerabilities are or how efficiently you can respond to incidents. Network security automation solutions like Palo Alto’s Next-Generation Firewall (NGFW) and Datadog AIOps security and monitoring.

Network automation tools to offset the tech talent shortage

The following categories of network automation tools are designed to simplify network management workflows to ensure optimal performance and 24/7 availability.

Automated network configuration management

Network configuration management refers to the ongoing process of creating, deploying, and maintaining configurations for network devices and logic. Some of the tasks involved in network configuration management include device discovery, provisioning, and software and firmware updates. In addition, network configurations are monitored to ensure they don’t drift away from documented standards (configuration shift), and if needed, unauthorized changes are rolled back. This reduces the risk that an undocumented configuration tweak will introduce an unnoticed security vulnerability (such as the recent Fortinet authentication bypass exploit) and ensures consistent quality across the entire network architecture.

However, manual network configuration management is complicated and time-consuming, especially when so many network operations teams are overworked and understaffed. An automated network configuration management solution handles many of these tasks without the need for human intervention. Admins can create network configuration policies and playbooks which are used to automatically deploy new devices and update network dependencies, saving time and reducing human error. In addition, automated configuration management uses these policies to continuously monitor for and correct configuration drift. In the case of the Fortinet CVE, for example, automatic configuration management could have helped teams instantly roll back to the last known good config to close the vulnerability.

Examples of network automation tools for network configuration management include SolarWinds Network Configuration Manager and Micro Focus Network Automation.

DevOps IaC configuration management

Many organizations have adopted the DevOps methodology, which seeks to dissolve the barriers between the software development and IT operations teams to improve efficiency. On the Ops side, this often involves a practice called IaC, or Infrastructure as Code. IaC uses software code and machine-readable definition files to automatically provision servers and manage configurations. IaC enables Ops teams to spin up resources at the velocity required for fast-paced DevOps software projects. It also means that infrastructure configuration code can be stored, managed, and deployed from the same platform as software code, facilitating easy collaboration between developers and sysadmins.

With the recession forcing many IT teams to downsize, organizations are looking for ways to extend the efficiency provided by DevOps automation tools to the networking side of the house without purchasing additional solutions. Plus, many network admins lack the expertise required to operate network automation solutions, and the tech talent shortage makes recruiting such specialized engineers difficult. Luckily, some IaC configuration management tools like RedHat Ansible and Puppet can also be used for network configurations, which helps teams automate without any special programming skills.

That also means admins can deploy, monitor, and manage configurations for network devices and systems across the entire architecture from a single platform, saving money and reducing operational complexity. This convergence of DevOps and network management is known as NetDevOps or NetOps, and it’s empowering organizations to improve efficiency even during the recession and talent shortage.

Software-defined networking and SD-WAN

Enterprise networks are typically highly distributed and very complex. An organization could have 500 branch offices around the world, each of which uses slightly different networking hardware and software solutions. Each of these vendor solutions might have its own management platform for admins to configure, manage, and continuously monitor. Things grow more challenging when an organization uses a hybrid cloud infrastructure, which requires WAN (wide area networking) orchestration across multiple public and private clouds. This complexity makes it challenging for overworked network administrators to maintain optimal performance and 24/7 availability.

Software-defined networking (SDN) and software-defined wide area networking (SD-WAN) help to reduce the complexity of enterprise networks by abstracting network configurations and workflows as software code that’s decoupled from the underlying hardware. Codifying network configurations makes it easier to use technology like automated configuration management, which reduces the burden on overworked admins and reduces human error. SDN and SD-WAN also facilitate the use of centralized network orchestration platforms, which give admins a single pane of glass from which to control the entire network architecture.

This holistic coverage makes it possible for small teams to efficiently monitor and manage large, complex networks, reducing the risk of fatigue, human error, or negligence affecting performance. Plus, SDN and SD-WAN solutions employ automation to continuously monitor and adjust routing configurations as needed to ensure optimal performance. That means these solutions are often able to detect and remediate issues with latency and site availability much faster than a human admin could, ensuring optimal performance and reliability.

Examples of SDN and SD-WAN solutions include Cisco Meraki SDN and Palo Alto Prisma SD-WAN.

Network security automation

With the quantity, sophistication, and cost of cybersecurity attacks rising every year, network security is more important than ever. According to the Sophos State of Ransomware 2022 survey, 66% of organizations were hit by ransomware, a massive increase from 2020 in which only 37% of organizations were attacked.

However, the tech talent shortage and ongoing recession have left many organizations with gaps that increase both the risk that a breach will occur and the time it will take to recover. For example, IBM estimated in 2021 that unpatched vulnerabilities accounted for at least one-third of all data breaches. However, staying on top of patch management for large, diverse, and distributed network infrastructures is difficult when teams are overworked and understaffed.

Plus, when networking and security teams are spread so thin, it can take them much longer to detect a breach that has already occurred, even if the hacker is actively exfiltrating data or changing system configurations. Remediation is also slowed down by the need to manually investigate logs, isolate affected systems, and implement fixes.

Network security automation can help bridge these gaps by reducing the need for human analysts to perform the more tedious and repetitive – but highly vital – tasks involved in ongoing cybersecurity management. Automated security solutions use technology like AIOps and machine learning to manage software and firmware updates, analyze network traffic for threats, and even perform remediation steps like quarantining infected systems and blocking compromised accounts.

Popular examples of network security automation tools include Palo Alto Network’s Next Generation Firewall (NGFW) and Datadog AIOps Security and Monitoring.

Using a vendor-neutral platform to deploy network automation tools

The goal of automation is to make it easier for network admins to maintain and optimize the enterprise network. However, if admins need to learn, configure, deploy, and manage a bunch of additional automation solutions, you could end up increasing the complexity of their jobs rather than reducing it.

The Nodegrid platform can help by directly hosting all of the network automation tools listed above, reducing the need for additional hardware to manage. Deploying Nodegrid boxes in all your data centers and remote sites gives you the ability to extend automation to every corner of your network and manage it all from behind a single pane of glass. Hosting your network automation on a vendor-neutral platform like Nodegrid gives your team an easy way to orchestrate automated workflows across your entire enterprise architecture.

Network automation tools help to bridge the gaps caused by the tech talent shortage, ensuring the reliability and resilience of enterprise networks.

The Importance of Remote Site Monitoring for Network Resilience

remote site monitoring

Enterprise networks are huge and complex, with infrastructure hosted in many different facilities across a wide geographic area. Though most network infrastructure isn’t housed in the same location as the core business, it’s still vital to the business’s continual operation. Remote site monitoring gives network admins a virtual presence in remote sites like data centers, manufacturing facilities, electrical substations, water treatment plants, and oil pipelines.

Most organizations already have some form of remote infrastructure monitoring, but traditional solutions come with major limitations that make it difficult for networking teams to maintain 24/7 uptime. In this blog, we’ll discuss the importance of remote site monitoring, analyze the limitations of traditional solutions, and explain how the ideal remote monitoring platform improves network resilience.

The importance of remote site monitoring

Many organizations have reduced their IT staff due to the economic recession, leaving networking and infrastructure teams stretched too thin. When there aren’t enough eyes on remote infrastructure, enterprise networks are more vulnerable to breaches, hardware failures, and other major causes of network outages. With the average cost of downtime rising above $100k in 2022, and cyberattacks causing major disruptions to oil pipelines in recent years, this is a problem that’s too expensive to ignore.

The limitations of traditional remote site monitoring solutions

Many organizations rely on remote site monitoring solutions that are fragmented and vendor-specific. Admins have to log in to one platform to view monitoring data for a remote site’s wireless access points, for example, and a different platform to monitor IoT devices in the warehouse. These complex and repetitive tasks can lead to fatigue and negligence, especially for overworked and understaffed networking teams. At an even higher level, this makes it difficult to see the relationships between different systems and solutions or get a complete picture of the overall health of the enterprise network.

Another limitation of traditional solutions is that they’re often affected by the same issues as the infrastructure they’re monitoring. For example, if the LAN goes down in a remote office and the on-premises security appliance can’t get an IP address, then admins won’t be able to remotely access that appliance to view the monitoring logs. This can significantly delay or even prevent remote diagnostic and recovery efforts, leading to expensive truck rolls.

The problem gets even worse if the remote site is inaccessible due to natural disasters, conflicts, or other external factors. Network teams need a way to get eyes on the problem, diagnose the root cause, and deploy fixes without physically seeing or touching the affected infrastructure.

The ideal remote site monitoring solution

To avoid these limitations and ensure network resilience, the ideal remote site monitoring solution should consider the following factors:

Vendor-neutral and centralized

A vendor-neutral monitoring platform can collect and analyze logs from every component of your infrastructure. This gives admins complete coverage, so nothing falls between the cracks.

Another benefit of vendor neutrality is that it enables unified, centralized monitoring. That means networking teams only need to log in to a single portal to observe the entire distributed enterprise architecture.

Out-of-band

Deploying remote site monitoring on an out-of-band (OOB) network means that it won’t rely on production LAN, WAN, or ISP infrastructure. This ensures that admins always have access to vital monitoring data even during an outage, making it easier to remotely diagnose the issue.

Plus, using an OOB management solution for monitoring improves network resilience even further by giving admins a direct connection to remote infrastructure that doesn’t require an IP address. That means they can still access and fix remote devices during an outage.

Automated

Automated monitoring solutions help to ensure that admins are quickly notified of potential issues and that possible remediation steps are taken even if nobody is available right away. Some solutions can, for example, automatically refresh DHCP on a device that lost its IP address or re-direct traffic to a secondary resource when the primary server stops responding.

Automated monitoring solutions help to reduce the workload on understaffed networking teams without sacrificing resilience.

Building network resilience with ZPE Systems

A centralized, vendor-neutral remote site monitoring solution with out-of-band management and automation support helps to ensure network resilience even when IT staff is reduced or remote sites become inaccessible. The Network Automation Blueprint from ZPE Systems provides a reference architecture for achieving network resilience with OOB, automation, monitoring, and more.

White Box Networking: Making the Switch

A close up of fingers plugging an Ethernet cable into a white box networking switch
Vendor lock-in is risky to corporate revenue and security. Enterprise technology ends up on rails, so to speak. Organizations lose the ability to choose the best features, pricing, and functionality for their use cases and instead must go along with their vendor’s roadmap. This is leading executives to take a hard look at their existing networking tech stacks so they can break out of their closed ecosystems. White box networking solutions, which are designed around completely open and customizable hardware components, offer an escape from vendor lock-in. In this blog, we’ll discuss how white box networking works, what the benefits and challenges are, and how to build the best solution.

White box networking explained

White box networking involves the use of hardware – like switches and routers – that are built with commodity parts and can run any software. These solutions are highly customizable, enabling organizations to mix and match parts from different suppliers to get exactly the features they need, like port configurations, storage capacity, and computational power. In addition, white box devices can run operating systems and software that’s been custom-made or heavily modified, allowing even greater flexibility.

The benefits of white box networking
.

Cost savings: Network Operating Systems (NOS) are often the most expensive component of a networking solution, involving recurring licensing fees, support contracts, and periodic update costs. Plus, the vendor may decide to overhaul or replace their software platform, requiring expensive network hardware replacements and licensing upsells to maintain support. White box networking decouples the hardware and software, giving organizations complete control over their NOS and allowing the use of open source or in-house operating systems. By eliminating their reliance on commercial NOS, companies can reduce both their upfront software costs and their recurring licensing fees.

Hardware and software freedom: Even if an off-the-shelf networking solution comes with the necessary features and functionality right now, that’s no guarantee that the feature roadmap will always align with an enterprise’s goals and future growth. A white box solution can be changed at any time by installing new software or replacing hardware components, so it can grow and evolve with an organization. This also means that companies can take advantage of new and emerging technologies like SD-WAN or AIOps as quickly as they want without needing to completely replace the underlying infrastructure – they can simply add the required hardware and software to their existing white box solutions.

Easy management and interoperability: The biggest benefit of white box networking is that it can be managed by any platform and integrated with any third-party solutions. This makes it easier for an organization to create a fully unified environment with centralized orchestration, end-to-end network automation, and complete visibility. Network teams get holistic control over the entire white box infrastructure from a single pane of glass, using their preferred automation scripts and orchestration tools, which ensures greater performance, reliability, and efficiency.
.

The problem with white box networking

Though white box networking has many advantages in theory, a lot of companies find it hard to achieve these benefits in practice. For one thing, many white box vendors focus simply on the hardware and don’t provide a default NOS. That means organizations need to spend additional time purchasing, customizing, or writing their own NOS as well as deploying that NOS to all new white box devices.

In addition, white box hardware is often sold in bulk and can become prohibitively expensive if bought in smaller quantities. An organization might end up buying a lot of extra parts they don’t need just to avoid outrageous shipping fees, and then they’re left with the hassle of storing or reselling that hardware.

White box networking also requires a lot of extra work to configure, deploy, and manage compared to a commercial off-the-shelf (COTS) solution. For many companies, the complexity of enterprise networks and the tech talent shortage make white box networking too much of a headache. Plus, white box manufacturers typically don’t provide ongoing support in the form of NOS updates and security patches, which means the enterprise must take on this responsibility themselves.

Plus, white box devices can also increase the security attack surface of the enterprise network. A poorly configured and unpatched NOS is a tempting target for cybercriminals, who can use a compromised white box device to access sensitive network resources.

The solution: White box networking with ZPE Systems

To use white box networking effectively while avoiding these challenges, you need a complete solution, not just disparate parts to assemble on your own. That solution should combine the open ecosystem approach of white box hardware, the centralized management and security patch advantages of point solutions, and pre-validated applications that don’t require a professional coder to deploy.

For example, the Nodegrid platform from ZPE Systems turns white box networking into a complete enterprise solution. Nodegrid devices are highly customizable, inexpensive, and arrive fully assembled. These devices come pre-installed with the Nodegrid OS, which is built on an x86-64 bit Linux kernel to ensure easy setup and interoperability. ZPE Systems can even manage Nodegrid OS updates and security patches for you, helping to reduce your attack surface and close the tech talent gap. Plus, you can directly host or integrate your choice of networking applications (including Docker containers and SASE solutions) for greater functionality, security, and ease of use.

The Nodegrid solution addresses every major challenge of white box networking so you get complete vendor freedom and simplified management in a single, affordable platform.

Why You Need an Out-of-Band Cybersecurity Platform

out of band cyber security
As enterprise networks continue to grow in size and complexity, many organizations struggle to defend their expanding attack surface. The cost of failure also continues to grow – according to IBM’s 2022 Cost of a Data Breach report, the average cost of a successful ransomware attack reached $4.54 million. Koroush Saraf, VP of Product Management at ZPE Systems, identified the top five cybersecurity gaps that must be closed to achieve holistic cybersecurity, which include:

  • Unnecessary exposure of management ports
  • Credential theft
  • Unpatched infrastructure
  • Inability to deploy the right security tools
  • Human error

Closing these gaps requires a three-pronged approach – out-of-band infrastructure, an open platform from which to deploy and manage security tools, and end-to-end automation (aka, hyperautomation). In this blog, we’ll explain how an out-of-band cybersecurity platform combines these three key features into a single, holistic network security solution. Want to see an out-of-band cybersecurity platform in action? Request a free demo of the Nodegrid solution.

Why you need an out-of-band cybersecurity platform

An out-of-band (OOB) cybersecurity platform provides a single, unified interface from which to:

  • View and manage network infrastructure
  • Deploy and control all of the various security policies and applications needed to protect that infrastructure, and
  • Orchestrate network, infrastructure, and security automation.

This platform resides and operates on an out-of-band network running parallel to the production network, which ensures 24/7 availability even if there’s a LAN failure or ISP outage. All network, infrastructure, and security management occur OOB, which prevents resource-intensive orchestration workflows from negatively impacting performance. This vendor-neutral, automation-friendly, out-of-band approach to cybersecurity helps you in several areas.

Reduce your attack surface

The management ports on devices like servers and switches are frequently targeted by cybercriminals because they can be used to gain access to valuable data and resources on the production network. With an out-of-band cybersecurity platform, all infrastructure and network management occurs on the OOB network, which means you no longer need to expose management ports on the production network. Isolating management and orchestration workflows to the OOB network helps reduce the attack surface by making it much more difficult for attackers to find and access those open management ports. Vendor-neutral OOB cybersecurity platforms can also help companies reduce the number of individual devices and solutions on their network, which decreases the attack surface even more. An open OOB serial console like the Nodegrid Serial Console Plus (NSCP) can host other vendors’ applications and solutions and seamlessly integrate them into the cybersecurity platform, so there are fewer devices to patch and defend, and fewer vectors through which cybercriminals can attack.

Understand your attack surface

A centralized, vendor-neutral cybersecurity platform is able to dig its hooks into every component of an enterprise network, providing a complete overview of the entire architecture. With this holistic view, security analysts gain a better understanding of the attack surface and what’s needed to protect each vulnerability. For example, a cybersecurity platform can provide information about software versioning to help with security patch management or help identify which ports are open in various applications and why. Armed with this knowledge, an organization can then deploy granular policies, tools, and controls that are custom-tailored to provide the best defense.

Mitigate human error

Even the best network engineer, working in the ideal environment, will occasionally make mistakes. For example, a recent FAA outage that delayed thousands of flights was caused by a contractor mistakenly deleting some files. And unfortunately, the combination of a tech industry recession and a tech talent gap has meant that many IT teams are overworked and understaffed – far from an ideal situation. Human error is a leading cause of successful breaches, so network automation can reduce human error by letting scripts and playbooks handle many of the tedious and repetitive workflows involved in network management. An out-of-band cybersecurity platform can host or integrate with all the leading automation solutions and scripting languages, giving overworked admins the freedom to use the tools they’re most comfortable with. The centralized platform consolidates automated workflows in a single place for streamlined deployments and efficient management. Organizations can even achieve hyperautomation – automating every task and workflow across the network and security architecture – using the cybersecurity platform as an orchestration hub. This empowers understaffed teams to optimize network performance and security while reducing manual interventions, mitigating the risk of human error.

Ensure 24/7 coverage and availability

An out-of-band cybersecurity platform uses a dedicated network interface – such as a 5G cellular modem – to ensure continuous management access even when there’s an outage on the production network. That means admins have 24/7 access to the cybersecurity platform itself, as well as the devices and systems being protected by that platform. And, crucially, all of the security policies and tools will continue to protect production network infrastructure during that downtime. This continuous availability makes it possible for IT teams to remotely recover from device and network failures without the need for costly and time-consuming truck rolls. Or, in the event of a successful attack such as ransomware, admins can conduct recovery operations on the OOB network, creating an isolated recovery environment (IRE) that’s inaccessible to attackers.
