Zero Trust Networking

Traditional enterprise security often relied heavily on a network boundary. Traffic outside the boundary was treated as suspicious, while users and devices on the internal network received broader access.

That model becomes fragile when employees work remotely, applications run across several clouds, services communicate across clusters, and compromised devices can appear inside the network. An attacker who steals a VPN credential or compromises one internal host may inherit network reachability to many systems that were never part of the original target.

Zero trust changes the unit of access control. Instead of asking only, “Is this connection coming from the internal network?”, it asks:

Zero trust is an architectural approach, not a protocol, appliance, or product. Its goal is to remove unnecessary implicit trust and make access to resources explicit, narrowly scoped, and continuously observable.
