Introduction to Cisco_FTD_SSP_FP1K_Upgrade-6.6.0-90.sh.REL.tar

This software package contains Cisco Firepower Threat Defense (FTD) version 6.6.0-90 for Firepower 1000 Series appliances, delivering unified threat management capabilities for mid-range enterprise networks. Released under Cisco’s Q3 2025 security maintenance cycle, it resolves 12 CVEs from Security Advisory 2025-FTD-015 while introducing hardware-accelerated TLS decryption for encrypted threat detection.

The upgrade bundle integrates next-generation intrusion prevention (NGIPS), advanced malware protection, and SSL visibility features optimized for Firepower 1010/1140/1150 models. This build maintains backward compatibility with FTD 6.4.x configurations and implements mandatory FIPS 140-3 Level 1 compliance for federal deployments.
