Introduction to “cisco-asa-fp3k.9.19.1.22.SPA” Software

The cisco-asa-fp3k.9.19.1.22.SPA is Cisco’s maintenance release for Firepower 3000 Series appliances operating in Adaptive Security Appliance (ASA) mode, delivering critical security updates and hardware optimizations. Released in Q1 2025 as part of the 9.19 Extended Maintenance Release (EMR) cycle, this build addresses 21 CVEs while maintaining backward compatibility with FPR-3110/3130/3140 hardware manufactured after Q4 2022.

Designed for enterprise-grade network protection, this version introduces enhanced cryptographic acceleration for Firepower 3140’s 800Gbps interfaces and improves cluster synchronization efficiency. The “fp3k” designation confirms dedicated optimization for 3U Firepower 3000 chassis with quad supervisor modules.
