Introduction to cisco-asa-fp3k.9.17.1.20.SPA Software
The cisco-asa-fp3k.9.17.1.20.SPA is Cisco’s firmware package for Firepower 3100 series security appliances running Adaptive Security Appliance (ASA) software. Released in Q4 2024, this maintenance build enhances threat defense capabilities while maintaining backward compatibility with existing VPN configurations and firewall policies. Designed for enterprise network core protection, the 478MB package supports hardware-accelerated TLS 1.3 inspection on FPR-3140/3150 models through Cisco’s Unified Threat Defense architecture.
This version introduces enhanced interoperability with Cisco Secure Firewall Management Center 7.8+ and maintains compatibility with hybrid deployments combining physical ASA appliances with ASAv virtual instances. The “fp3k” designation confirms optimization for Firepower 3100’s Intel Xeon Scalable processors and 100GbE interface modules.
