Out-of-Band Management: What It Is and Why You Need It

This post was originally published on ZPE Systems

Modern companies face the monumental challenge of delivering digital services with 100% uptime. Factors like the complexity of their network infrastructure, the widespread geographical distribution of business sites, and the ever-increasing threat of ransomware and other cyberattacks are major hurdles to maintaining availability. Out-of-band management offers the solution: a way for teams to access critical remote infrastructure during outages and breaches without “out-of-chair” expenses. Out-of-band management allows organizations to recover remote infrastructure faster, reducing the duration and expense of downtime.

This guide to out-of-band management answers critical questions about what this technology is, why you need it, and how to choose the right solution.

What is out-of-band management?

Out-of-band (OOB) management involves controlling network infrastructure and workflows on an out-of-band network. An out-of-band network is an entirely separate network that runs parallel with your production (or in-band) network but doesn’t rely on any of the same infrastructure or services. OOB management allows teams to administer network infrastructure remotely on a dedicated connection, such as secondary Fiber or cellular LTE, that will remain available even if the in-band network goes down from an equipment failure, ISP outage, or ransomware attack.
