Introduction to Cisco_FTD_SSP_Upgrade-7.2.4-165.sh.REL.tar

This critical security patch resolves multiple vulnerabilities in Cisco Firepower Threat Defense (FTD) software version 7.2.4, specifically targeting Firepower 2100/4100 series appliances (FPR2110/FPR2140/FPR4140). Released through Cisco’s Extended Maintenance Release (EMR) program in Q2 2025, the upgrade package addresses 9 documented CVEs while maintaining NGFW functionality for enterprise security deployments.

The software preserves existing firewall policies during deployment through Firepower Management Center (FMC) and supports hardware-accelerated threat inspection on FPR4100 series devices. As part of Cisco’s security maintenance lifecycle, this patch extends vulnerability coverage for legacy Firepower appliances through 2026.
