Traditional network security was built around a perimeter: strong defences at the edge, implicit trust for anything already inside it. That model breaks down once you account for remote work, cloud services, and how often attackers get a foothold through a compromised account rather than by breaching the perimeter directly.
Zero Trust starts from a different assumption: verify every request, regardless of where it's coming from, rather than trusting it by default because it's already inside the network. Identity, device health, and context all get checked continuously, not just at the login screen.
For most businesses, adopting Zero Trust isn't a single project: it's a direction to move in gradually, starting with the highest-value systems and expanding from there. The underlying principle is simple even if the rollout isn't: never trust, always verify.
