Introduction to cisco-asa-fp2k.9.20.2.10.SPA
The cisco-asa-fp2k.9.20.2.10.SPA software package delivers Cisco Secure Firewall Adaptive Security Appliance (ASA) Software version 9.20.2.10, specifically engineered for Firepower 2100 Series hardware platforms (FPR-2110/2130/2140). As a Security Package Archive (SPA), this maintenance release addresses critical vulnerabilities (CSCwd38245, CSCwe77521) while enhancing platform stability in clustered deployments and hybrid security architectures.
This build integrates ASA firewall services with Firepower Threat Defense capabilities, supporting unified threat management for enterprises requiring granular policy enforcement across physical/virtual environments. The version numbering follows Cisco’s standardized format where “9.20” denotes the major feature branch, “2” indicates the maintenance release, and “10” specifies the interim build containing security patches.
