Introduction to secure-firewall-posture-5.0.01242-k9.pkg Software

The secure-firewall-posture-5.0.01242-k9.pkg is a critical compliance enforcement module for Cisco Secure Client 5.x deployments, designed to validate endpoint security configurations against organizational policies. Released in Q3 2024 as part of Cisco’s Zero Trust Architecture updates, this package enables automated checks for OS patch levels, antivirus status, and encryption compliance across Windows, macOS, and Linux endpoints.

This version specifically integrates with Cisco Secure Firewall ASA 9.18+ and Firepower 4100/9300 appliances, replacing the legacy HostScan module in AnyConnect 4.x deployments. It becomes mandatory when using Cisco Secure Client 5.0.01242 or later for enterprises requiring FIPS 140-2 validated endpoint assessments.
