Introduction to Cisco_FTD_SSP_FP3K_Upgrade-7.2.3-77.sh.REL.tar
This upgrade package delivers Firepower Threat Defense (FTD) 7.2.3-77 for Cisco Firepower 3100 SSP Series Security Appliances, addressing 9 critical CVEs identified in Cisco’s Q1 2025 Security Advisory Bundle. Designed for enterprises requiring advanced threat prevention, this release introduces quantum-resistant encryption trial support and Azure Arc-enabled policy synchronization.
Compatible with Firepower Management Center (FMC) 7.8+, the build enhances TLS 1.3 inspection throughput by 40% compared to previous 7.2.x versions through Intel QAT 4.3 hardware acceleration. Officially released in March 2025, it maintains backward compatibility with ASA 5500-X migration configurations while optimizing resource allocation for encrypted traffic analysis in hybrid cloud environments.
