Introduction to FGT_2500E-v6-build1911-FORTINET.out
This firmware package delivers FortiOS 6.4.7 for FortiGate 2500E Series hyperscale firewalls, engineered for enterprise data centers requiring multi-100Gbps threat protection with carrier-grade reliability. Released in Q1 2025, the build addresses 21 CVEs from Fortinet’s security advisories while introducing hardware-accelerated TLS 1.3 post-quantum cryptography enhancements for future-proof network security.
Optimized for FG-2500E hardware platforms, the firmware enhances NP7 ASIC utilization efficiency by 35% compared to FortiOS 6.4.6. It supports integration with FortiManager 7.6.3+ for centralized policy orchestration and enables 400Gbps MACsec-enabled network backbones for hyperscale deployments.
