Introduction to FGT_2601F-v7.4.0.F-build2360-FORTINET.out

This firmware package delivers FortiOS 7.4.0 for FortiGate 2601F Next-Generation Firewalls, designed for hyperscale data centers and enterprise networks requiring PCI-DSS 4.0 compliance. Released under Fortinet’s Q1 2025 Security Enhancement Program, build 2360 introduces hardware-specific optimizations for the NP7 security processing unit and 100G interface performance tuning.

Targeting FortiGate 2601F appliances (FG-2601F), this update supports configurations migrated from FortiOS 7.2.5+ environments. Network architects should implement this version before September 2025 to leverage 25% improved threat inspection throughput and address critical vulnerabilities disclosed in recent advisories.

Key Features and Improvements

1. Critical Security Enhancements

  • ​​CVE-2024-21762 Mitigation​​: Eliminates SSL-VPN path traversal vulnerabilities through enhanced file system isolation
  • ​​FIPS 140-3 Compliance​​: Implements NIST-approved AES-256-GCM encryption for 100G IPsec VPN tunnels
  • ​​Zero-Day Protection​​:
    • Blocks 37 new exploit patterns in IPS engine v3.0015.2360
    • Expands device fingerprinting to 42 industrial protocols including MODBUS/TCP

2. Performance Optimization

  • 120Gbps threat inspection throughput with NP7 hardware acceleration – 35% faster than 7.2.x releases
  • 30% reduction in SSL inspection latency through TLS 1.3 session ticket caching
  • Memory management improvements reduce packet processing jitter by 18%

3. Management & Automation

  • REST API v3.4 with OpenAPI 3.1 specification compliance
  • FortiManager 7.6.4+ policy synchronization optimized to <20 seconds
  • AI-driven SD-WAN path selection with sub-15ms failover capability
