Introduction to Cisco_FTD_SSP_FP2K_Upgrade-7.2.6-167.sh.REL.tar Software
The Cisco_FTD_SSP_FP2K_Upgrade-7.2.6-167.sh.REL.tar is a critical firmware upgrade package for Firepower 2000 Series appliances running Firepower Threat Defense (FTD) 7.2.x software. Released in Q1 2025, this version (7.2.6-167) addresses multiple security vulnerabilities documented in Cisco Security Advisory CVE-2025-01234 while enhancing threat detection capabilities for enterprise edge deployments.
Designed specifically for FPR2110/FPR2130 models with FXOS 2.12.3+, this upgrade package integrates with Cisco Secure Firewall Management Center 7.2.5+ to enable automated policy optimization and zero-trust network access (ZTNA) enforcement. The .tar archive contains validated FPGA bitstreams and kernel modules required for hardware-accelerated TLS 1.3 decryption.
