Introduction to cisco-asa-fp3k.9.19.1.9.SPA
The cisco-asa-fp3k.9.19.1.9.SPA package delivers Cisco Secure Firewall Adaptive Security Appliance (ASA) Software version 9.19.1.9, specifically engineered for Firepower 3000 Series hardware platforms (FPR-3100/FPR-4100). This maintenance release addresses critical vulnerabilities (CSCwd38245, CSCwe77521) while enhancing platform stability in clustered deployments. Designed as a Security Package Archive (SPA), it integrates ASA firewall services with Firepower Threat Defense capabilities for unified threat management in enterprise hybrid networks.
Compatible with FPR-3100/FPR-4100 appliances running FXOS 2.12.1+, this build supports multi-gigabit security architectures requiring granular policy enforcement across physical and cloud environments. The version numbering follows Cisco’s standardized format where “9.19” denotes the major feature branch, “1” indicates the maintenance release, and “9” specifies the interim build containing security patches.
