Introduction to cisco-ftd-fp2k.7.0.4-55.SPA Software

The cisco-ftd-fp2k.7.0.4-55.SPA software package delivers essential security updates and architectural improvements for Cisco Firepower 2100 Series appliances running Firepower Threat Defense (FTD). Released through Cisco’s Security Advisory program in Q2 2025, this maintenance release addresses 8 critical CVEs while introducing NIST SP 800-53 Rev.6 compliance enhancements.

Designed for Secure Firewall Platform (SSP) architectures, version 7.0.4-55 maintains backward compatibility with FTD 7.0.x configurations. The .SPA package contains encrypted firmware binaries with integrated validation scripts, ensuring secure deployment through Cisco’s FXOS validation framework.
