Cisco TrustSec (CTS) is a comprehensive security architecture that provides identity-based access control and encrypted communication across the network infrastructure. It uses Security Group Tags (SGTs) to classify and label traffic based on user identity, device type, or security posture, enabling consistent security policy enforcement regardless of network topology or IP addressing. TrustSec integrates authentication, authorization, encryption, and policy enforcement to create a secure network fabric that can adapt to changing security requirements and threat landscapes.
