Introduction to cisco-asa-fp2k.9.20.3.SPA

The ​​cisco-asa-fp2k.9.20.3.SPA​​ is a firmware package designed for Cisco Firepower 2100 Series appliances running Adaptive Security Appliance (ASA) software. This maintenance release addresses 9 CVEs identified in prior versions while maintaining backward compatibility with hybrid network architectures. As part of Cisco’s Q3 2024 security update cycle, it enhances threat prevention capabilities for Firepower 2110/2130 models and virtualized ASA instances on VMware ESXi 8.0 U2.

This version belongs to the 9.20(x) extended support branch, providing critical security updates without introducing major feature changes. The package integrates OpenSSL 3.0.14 with hardware-accelerated DTLS encryption for VPN performance improvements.
