Introduction to cisco-asa-fp2k.9.20.3.13.SPA

The ​​cisco-asa-fp2k.9.20.3.13.SPA​​ is a maintenance release for Cisco Firepower 2100 Series appliances running Adaptive Security Appliance (ASA) software. Designed as a security-focused update, this package addresses 9 critical CVEs while enhancing threat inspection capabilities for hybrid cloud environments. Compatible with FPR2110/2120/2140 hardware models, it supports clustered configurations of up to 16 nodes with hardware-accelerated encryption for VPN workloads.

Released in Q1 2025, this version introduces optimizations for TLS 1.3 session handling and industrial control system (ICS) protocol security. It maintains backward compatibility with Firepower Threat Defense (FTD) 7.8+ management systems while delivering 25% improved throughput for encrypted traffic inspection compared to previous 9.20.x releases.
