Why network segmentation matters
A flat network is a fast network for attackers too. Segmentation is one of the highest-leverage changes most organisations can make.
In a flat, unsegmented network, a single compromised device can often reach far more of the environment than it should. Segmentation divides a network into zones: separating, for example, guest Wi-Fi from finance systems, or production systems from administrative endpoints.
Done well, segmentation limits lateral movement: even if an attacker gains a foothold, their ability to reach critical systems is constrained by the boundaries between zones.
Segmentation isn't just a firewall exercise. It requires understanding how systems actually communicate, so that boundaries reflect real traffic patterns rather than guesswork.
