1. Introduction to “cisco-asa-fp2k.9.12.4.4.SPA” Software

The “cisco-asa-fp2k.9.12.4.4.SPA” is a critical security software package for Cisco Firepower 2100 series appliances, designed to convert these Next-Generation Firewalls (NGFWs) from Firepower Threat Defense (FTD) mode to Cisco Adaptive Security Appliance (ASA) operation. Released in Q3 2024 as part of Cisco’s Extended Maintenance Release (EMR) cycle, this build combines ASA software version 9.12.4.4 with Firepower eXtensible Operating System (FXOS) platform enhancements.

This package enables organizations to leverage ASA’s mature security policy framework on Firepower 2100 hardware (FPR-2110/FPR-2130/FPR-2140), supporting hybrid deployment models where ASA and FTD functionalities coexist in separate security domains. The software maintains compatibility with Cisco SecureX platform integrations and provides transitional support for legacy ASA feature sets in modern threat landscapes.
