Introduction to “cisco-ftd-fp1k.7.2.1-40.SPA” Software
This software package provides the Firepower Threat Defense (FTD) 7.2(1.40) system image for Cisco Firepower 1000 series security appliances, delivering unified threat management capabilities for enterprise network environments. Released in Q4 2024, this maintenance update focuses on enhancing encrypted traffic inspection accuracy while maintaining backward compatibility with existing security policies.
The .SPA format bundle contains both the FTD application image and necessary platform dependencies, supporting hardware-accelerated TLS 1.3 decryption on Firepower 1120/1140 devices with SSP (SecureX Streaming Processor) security modules. Administrators can implement zero-trust network access policies through integrated Cisco Identity Services Engine (ISE) 3.4+ compatibility.
