You can find blind spots in network monitoring by systematically checking which network segments, protocols, and devices fall outside the visibility of your monitoring tools. The most common gaps exist in physical layers, encrypted traffic, cloud environments, and devices that have never been actively configured for monitoring. This article answers the most frequently asked questions about detecting and addressing monitoring gaps in your network.<\/p>\n
Blind spots in network monitoring most commonly occur at the intersections of network segments, in encrypted traffic, and in environments that fall outside standard management tools. Think of IoT devices, OT networks, cloud connections, and physical infrastructure at OSI layers 1 and 2 that are rarely actively monitored. These are precisely where the greatest risks lie.<\/p>\n
In practice, we see a number of recurring problem areas:<\/p>\n
