Having a resilient data center network is a top priority for the modern enterprise. Network failures can lead to costly downtime, security vulnerabilities, and operational disruptions. To mitigate these risks, companies invest in out-of-band management, cellular failover, next-generation firewalls (NGFWs), and automation. But, it can be hard to know what’s just a feature and what makes a truly resilient infrastructure solution. To help navigate this, we put together this out-of-band management vendor comparison that breaks down how Opengear, Perle, and Lantronix compare to ZPE Systems.
Out-of-Band Management
Out-of-band (OOB) management is critical for maintaining network access during outages or cyber incidents. OOB typically gives admins access via dedicated serial ports, and it’s mainly used during emergencies when devices or services fail and need to be restored. However, because of digital transformation initiatives like hybrid-cloud, Infrastructure-as-Code, and AI adoption, OOB’s requirements have evolved past simple remote troubleshooting. It must seamlessly integrate into diverse, multi-vendor environments, provide flexible automation, and be able to scale without adding management complexity.
Takeaway: ZPE Systems’ open architecture and ability to scale in diverse environments give it the edge, as it’s better suited to meet OOB’s modern requirements.
Isolated Management Infrastructure
Resilience requires a dedicated, autonomous layer for management. Isolated Management Infrastructure (IMI) is that layer. Unlike traditional OOB, IMI provides a physically and logically separated control plane that remains operational even when the production network is compromised. It’s essential for running services like monitoring, DNS, or firewalls independently from the primary network. Very few vendors offer true IMI support as part of their core platform.
Takeaway: Most vendors still treat management like traditional OOB, where it’s a tool for recovery and not proactive resilience. ZPE Systems is purpose-built for IMI, allowing businesses to maintain critical operations during outages or attacks.
Cellular Failover
Through outages, it’s no longer enough to just have a backup link. Cellular failover must ensure secure, intelligent, and seamless continuity. Many vendors provide cellular hardware, but few integrate the security, automation, and multi-carrier intelligence needed for real resilience.
Takeaway: While other vendors provide failover as a backup connection with limited intelligence, ZPE Systems stands out by combining carrier agility, security, and orchestration in one platform designed for business continuity.
Firewall Support
Organizations require more than just basic OOB access; they need platforms that can host advanced security services like Next-Generation Firewalls (NGFWs), DNS, and monitoring tools. Here’s how ZPE Systems compares to other OOB vendors in this regard:
Takeaway: While Opengear, Perle, and Lantronix provide OOB management solutions with some integrated firewall features, ZPE Systems stands out by offering a platform capable of hosting full-fledged NGFWs and other security services. This extensibility allows organizations to consolidate their infrastructure, reduce hardware sprawl, and enhance security within an isolated management environment.
Automation
Automation used to be a “nice to have” capability. Now, it’s critical for reducing human error, accelerating incident response, and enabling self-healing networks.
Takeaway: Most vendors focus on limited scripting or rules-based logic meant for small and simple deployments, not for scalable operations. ZPE Systems offers enterprise-wide automation that integrates with modern DevOps tools, enabling intelligent, self-healing infrastructure. For teams aiming to automate across distributed environments or achieve lights-out operations, ZPE Systems is the ideal solution.
Final Recommendation
OOB tools from Opengear, Perle, and Lantronix provide point solutions that help you react to network issues. On the other hand, ZPE Systems helps you achieve proactive resilience through isolation, service hosting, and automation. For organizations looking to stay one step ahead of outages, cyberattacks, and downtime, ZPE Systems offers a secure and scalable fabric.
