Introduction to cisco-asa-fp2k.9.16.3.23.SPA Software

The cisco-asa-fp2k.9.16.3.23.SPA firmware package delivers Cisco’s Adaptive Security Appliance (ASA) software for Firepower 2100 series hardware platforms. Designed as a security services processor (SSP) image, this release enables organizations to deploy ASA firewall capabilities on Firepower Threat Defense (FTD) compatible appliances while maintaining backward compatibility with existing VPN configurations.

This Q3 2024 release (version 9.16.3.23) focuses on enhancing cryptographic performance and addressing critical vulnerabilities identified in previous ASA releases. The software supports Firepower 2100 series appliances including 2110, 2120, 2130, 2140, and 2150 models, with native integration for Cisco Secure Firewall Management Center deployments.
