Introduction to cisco-asa-fp4200.9.20.3.13.SPA Software

The ​​cisco-asa-fp4200.9.20.3.13.SPA​​ firmware update delivers critical security enhancements and operational improvements for Cisco Firepower 4200 Series security appliances running Adaptive Security Appliance (ASA) software. Released in Q3 2024 as part of the ASA 9.20.3 maintenance cycle, this package addresses 8 CVEs while optimizing SSL inspection performance for modern enterprise networks.

Designed specifically for Firepower 4100/4200 Series hardware (FPR4110, FPR4120, FPR4140 models), the update strengthens threat prevention capabilities through enhanced TLS 1.3 session handling and improved cluster failover mechanisms. As a cumulative update in the 9.20.x lifecycle, it maintains backward compatibility with existing configurations while extending platform stability for enterprises requiring long-term deployment consistency.
