Cisco disclosed a maximum-severity zero-day in Identity Services Engine already exploited in the wild—enterprises running ISE for network access control face immediate risk to their zero-trust foundations and should treat patching as an emergency.

Cisco has released security updates to address a maximum-severity Identity Services Engine vulnerability that attackers are actively exploiting in the wild. [...]

Editorial Analysis

Why it matters

Cisco ISE is a cornerstone of network access control in European enterprises; active exploitation of a max-severity flaw can undermine the entire zero-trust posture and enable lateral movement at scale.

What to do

Treat Cisco ISE patching as a P1 emergency: apply updates immediately, hunt for compromise indicators, and validate compensating controls on all ISE-managed network segments.

Board brief

A critical zero-day in Cisco's widely deployed network access control platform is under active attack—immediate patching is required to protect enterprise network security.
