Zero Trust Security
A security model that assumes no user or device should be trusted by default, even inside the network perimeter.
Traditional security models trusted anything already inside the corporate network. Zero trust assumes breach is possible at any point and requires continuous verification of identity and device health for every access request, regardless of location. In practice, this means strict identity checks, network segmentation, and least-privilege access rather than one perimeter firewall doing all the work.
