Introduction Zero Trust requires you to make decisions based on identity, device posture, and context — not on network topology (VLANs). Cisco TrustSec (SGTs + TrustSec enforcement) lets you express who/what can talk to what using Security Group Tags (SGTs) instead of brittle VLANs. Cisco […]
Introduction Security Group Tags (SGTs) are the identity currency of Cisco TrustSec. Instead of binding policy to IPs/VLANs, ISE assigns an SGT (e.g., HR=10, Finance=20, Guest=30) to users/devices at authentication time. These tags travel (inline) or are distributed (via SXP) so switches, WLCs, and firewalls […]
Introduction Cisco TrustSec (CTS) is a next-generation access control framework that goes beyond traditional IP-based segmentation. Instead of relying on static VLANs and ACLs, it leverages Security Group Tags (SGTs) to dynamically classify traffic, enforce policies consistently across the enterprise, and scale security for modern […]
Introduction Downloadable ACLs (dACLs) let Cisco ISE push per-session, per-user ACLs to the WLAN edge at the moment of authorization—so wireless clients get only the access they need (internet-only, app-only, or micro-segmented). Instead of pre-staging many ACLs on the controller, ISE becomes the source of […]
