Introduction to FGT_3500F-v7.0.8.F-build0418-FORTINET.out

This firmware update delivers FortiOS 7.0.8 Feature Release for FortiGate 3500F series appliances, designed for hyperscale data center security operations. Released on May 15, 2025 (build 0418), it addresses critical vulnerabilities including CVE-2025-32756 while introducing enhanced threat intelligence capabilities. Exclusively compatible with FG-3500F hardware, this version achieves 25% faster SSL inspection throughput compared to FortiOS 7.0.7.

The update supports organizations requiring 100Gbps+ encrypted traffic inspection with ASIC-accelerated security processing. Backward compatibility extends to FortiOS 7.0.6 configurations, though downgrades from 7.2.x require full hardware reset.
