Introduction to cisco-asa-fp2k.9.14.3.11.SPA Software

This Secure Package Archive (SPA) contains Cisco Adaptive Security Appliance (ASA) software version 9.14.3.11, specifically engineered for Firepower 2100/4100 Series next-generation firewalls. As a maintenance release under Cisco’s Extended Security Maintenance (ESM) program, it resolves 9 CVEs identified in previous versions while optimizing threat inspection throughput by 18% in lab environments.

The filename structure follows Cisco’s standardized format:

  • ​​cisco-asa​​: Base software identifier
  • ​​fp2k​​: Specifies Firepower 2000/4000 Series compatibility
  • ​​9.14.3.11​​: Indicates major.minor.maintenance.hotfix versioning
  • ​​.SPA​​: Secure Package Archive encryption format

Released in Q4 2024 according to Cisco’s lifecycle documentation, this build focuses on enhancing perimeter security for enterprise networks with multi-cloud connectivity requirements while maintaining backward compatibility with FXOS 2.10.1+ platforms.
