Introduction to cisco-asa-fp2k.9.20.2.22.SPA

The cisco-asa-fp2k.9.20.2.22.SPA firmware package delivers critical security updates and platform optimizations for Cisco Firepower 2100 Series appliances running Adaptive Security Appliance (ASA) software. As the final maintenance release in the 9.20.x branch for this hardware series, it addresses 14 CVEs rated high/critical severity while maintaining backward compatibility with enterprise network configurations.

This software supports Firepower 2110/2120/2130/2140 models, integrating Cisco Talos threat intelligence updates and hardware acceleration improvements for industrial control system (ICS) protocol inspection. Released in Q4 2024 as part of Cisco’s Extended Security Maintenance (ESM) program, it provides extended vulnerability protection for organizations maintaining legacy network architectures.
