Zubiqo Strategic Assessment
Primary Impact
Enterprise organizations and US federal agencies relying on Cisco ISE for internal network access control.
Strategic Shift
The targeting of core identity and access management appliances to achieve silent, root-level persistence inside perimeter networks.
The Ripple Effect
We'll likely see a spike in secondary breaches over the next 6 months as attackers use their root access on unpatched ISE nodes to move laterally across enterprise networks.
