Introduction to cisco-ftd-fp3k.7.1.0-90.spa Software

The cisco-ftd-fp3k.7.1.0-90.spa software package delivers critical security updates and operational enhancements for Cisco Firepower 3100/4200 Series appliances running Firepower Threat Defense (FTD). Released through Cisco’s Security Advisory program in Q2 2025, this maintenance update addresses 6 CVEs while introducing NIST SP 800-207 zero-trust architecture compliance features.

Designed for Secure Firewall Platform (SSP) multi-instance deployments, version 7.1.0-90 supports simultaneous management of up to 8 virtual firewall instances on Firepower 4100/9300 chassis. The .spa package contains encrypted firmware binaries with integrated validation scripts for FXOS 2.3.1.55+ environments.
