"Zero Trust" sounds like a platform you buy. It isn't — it's a discipline you apply. The core idea is simple: no user, device or application is trusted by default, even inside your network. Every access request is verified, every session is limited, every action is logged.
In practice, mid-size organizations get the best return from three moves. First, strong identity: multi-factor authentication everywhere, and single sign-on so exceptions stand out. Second, device awareness: only known, healthy endpoints reach business applications. Third, segmentation: break the flat network into zones so a single compromised laptop cannot reach everything.
You don't need to boil the ocean. Pick one critical application, apply those three controls around it, measure the friction, then repeat. Managed alongside an MDR service, this becomes a 90-day rhythm rather than a two-year program.
