Introduction to Cisco_FTD_SSP_Upgrade-7.1.0-90.sh.REL.tar
This major upgrade package delivers Cisco’s Firepower Threat Defense (FTD) 7.1 platform enhancements for 2100/4100 Series appliances, addressing 12 CVEs identified in Cisco’s Q2 2025 security advisories. The 7.1.0-90 release introduces quantum-resistant cryptography for VPN tunnels and optimizes TLS 1.3 inspection performance for networks handling over 50Gbps throughput.
Designed for enterprises requiring FIPS 140-3 Level 2 compliance, this TAR archive contains both FXOS infrastructure upgrades and Snort 3.1-based threat detection modules. Cisco officially recommends deployment before June 2025 for environments processing healthcare or financial data through IPsec tunnels.
