Introduction to secure-firewall-posture-5.1.7.80-k9.pkg Software

The ​​secure-firewall-posture-5.1.7.80-k9.pkg​​ is a critical component of Cisco Secure Client (formerly AnyConnect), designed to enforce endpoint compliance checks for secure network access. This module replaces the legacy HostScan technology and integrates with Cisco Secure Firewall solutions to validate device security posture before granting VPN or zero-trust network access.

Compatible with Cisco Secure Firewall ASA 5500-X Series and Firepower Threat Defense (FTD) platforms, this version (5.1.7.80) was released in Q1 2025 as part of Cisco’s continuous security enhancement cycle. It supports endpoint assessment across Windows 10/11, macOS 13+, and major Linux distributions, ensuring organizations can maintain strict security policies for remote and hybrid workforce environments.
