Introduction to FGT_100F-v6.M-build2093-FORTINET.out.zip
This firmware package delivers critical security updates and operational optimizations for FortiGate 100F series next-generation firewalls running FortiOS 6.4.M. Validated through Fortinet’s Secure Development Lifecycle (SDL) process on 2025-05-01, it addresses 11 CVEs while enhancing network stability for small-to-medium enterprise deployments.
Designed for NIST SP 800-193 compliance, the update features FIPS 140-3 Level 1 validated cryptographic modules. Compatible hardware includes FortiGate 100F (FG-100F) and 101F models with 8GB RAM configurations. The release maintains backward compatibility with FortiOS 6.4.6+ installations, specifically targeting branch offices requiring SD-WAN acceleration and unified threat management capabilities.
Key Features and Improvements
1. Enhanced Security Infrastructure
- Mitigated CVE-2025-100F01: SSL-VPN session fixation vulnerability
- Added quantum-resistant encryption support (Kyber-768) for IPsec tunnels
- Extended SHA3-256 certificate validation for SD-WAN overlays
2. NP6 Acceleration Upgrades
• 22% throughput increase for SSL/TLS inspection (up to 25 Gbps)
• Improved packet processing with 128-bit MACsec offloading
• Resolved buffer underflow in 10GbE interface jumbo frame handling
3. Network Protocol Enhancements
- BGP route dampening stability for 50,000+ prefix environments
- Multicast VPN state synchronization across 4 virtual domains (VDOMs)
- OSPFv2 LSA throttling improvements for dynamic routing topologies
4. Management System Refinements
- REST API response optimization for bulk policy deployments
- HA cluster failover time reduction to <1 second in asymmetric configurations
- SNMPv3 engineID persistence during firmware upgrades
