Introduction to cisco-asa-fp1k.9.20.3.13.SPA

The cisco-asa-fp1k.9.20.3.13.SPA firmware delivers critical security updates and platform enhancements for Cisco Firepower 1000 Series appliances running Adaptive Security Appliance (ASA) software. As part of Cisco’s Long-Term Support (LTS) release cycle, this version focuses on maintaining operational stability while addressing 17 Common Vulnerabilities and Exposures (CVEs) identified in previous releases.

Designed specifically for Firepower 1000 Series hardware (FPR 1120, 1140, 1150), this SPA package integrates firewall services with unified threat management capabilities. Cisco’s release documentation confirms this build was published in Q4 2024 as a maintenance update for production environments requiring extended validation cycles.
