Introduction Load balancing in Cisco ISE is not just about distributing authentication requests—it’s about ensuring scalability, fault-tolerance, and seamless user experience across a complex enterprise network. As deployments scale from a few thousand endpoints to hundreds of thousands of daily authentications, the traditional direct-to-node access […]
Introduction Cisco Firepower Management Center (FMC) is the brain behind Cisco’s Next-Generation Firewalls (NGFWs). By integrating FMC with Cisco ISE using pxGrid, you allow FMC to consume contextual identity and group information (like usernames, endpoints, SGTs, compliance posture, threat scores).This enables dynamic policy enforcement on […]
Introduction In Threat-Centric NAC (TC-NAC), Cisco ISE doesn’t “hunt malware” itself—it ingests threat verdicts and enforces. With Cisco AMP for Endpoints (now Cisco Secure Endpoint), ISE subscribes to live threat events and dynamically quarantines or restricts infected hosts using VLAN changes, dACLs, or TrustSec SGACLs—automatically […]
Introduction “Who is on my network?” is only half the question—what they are matters even more. Cisco ISE’s Profiler turns raw signals (DHCP, RADIUS, SNMP, HTTP, device-sensor, NetFlow, etc.) into precise endpoint identities (e.g., “HP LaserJet Pro M404dn”, “Cisco 88xx IP Phone”, “Axis M30 camera”, […]
Introduction Wired networks still carry most enterprise East/West traffic, printers, IP phones, scanners, and user PCs. Cisco TrustSec replaces sprawling IP/VLAN ACLs with Security Group Tags (SGTs) and role-based enforcement. With ISE assigning SGTs at the port during 802.1X/MAB, your Catalyst switches can tag traffic […]
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 802.1X is the foundation of secure wired and wireless network access control in enterprise networks.With Cisco ISE, 802.1X authentication ensures that only authorized devices and users can connect to the corporate network — reducing the risk of data breaches and preventing rogue devices from […]
