Introduction to “cisco-ftd-fp2k.7.2.0-82.SPA” Software
This software package delivers Cisco Firepower Threat Defense (FTD) version 7.2(0.82) for Firepower 2100 series security appliances, specifically designed to address critical vulnerabilities while enhancing encrypted traffic inspection capabilities. Released as a maintenance update in Q4 2024, the .SPA bundle combines platform dependencies and security enhancements for organizations requiring unified threat management across hybrid infrastructure.
Targeting Firepower 2130/2140 models with SecureX Streaming Processor (SSP) modules, this release introduces quantum-resistant encryption prototypes while maintaining backward compatibility with existing ASA policy configurations. The update particularly benefits enterprises operating in regulated industries requiring FIPS 140-3 Level 2 compliance for cryptographic operations.
