Zero Trust: Continuous Trust Scoring Gate

Zero Trust Architecture replaces "trusted inside the perimeter, untrusted outside" with a Policy Decision Point that scores every access request from live signals and re-checks that score continuously. This simulator renders that policy engine in 3D: a stream of access requests flies from the network edge toward a protected resource through a Policy Enforcement Point gate, each carrying its own device-health, location-risk and behavioral signals combined into a decaying trust score. Switch between continuous Zero Trust re-verification — where a session can be revoked mid-flight the instant its live score drops below threshold — and a legacy perimeter model that checks trust exactly once and never looks again, then tune the trust threshold, decay rate and anomaly rate to see how policy choices reshape the admitted-vs-blocked balance in real time.
