1. Introduction to FGT_6000F-v7.4.1.F-build2463-FORTINET.out
This firmware release delivers critical security updates and hardware optimizations for Fortinet’s flagship FortiGate 6000F hyperscale firewall series. As part of FortiOS 7.4.1 Feature Release updates, build2463 addresses 14 CVEs while introducing next-generation threat prevention capabilities for enterprise networks and data centers.
Designed exclusively for FortiGate 6000F appliances running FortiOS 7.4.x, this Q2 2025 release extends hardware lifecycle support through 2028. The firmware maintains backward compatibility with configurations created in FortiOS 7.2.3+ while introducing enhanced Security Fabric integrations and zero-trust architecture components.
2. Key Features and Improvements

- Resolved authentication bypass risk (CVE-2025-29903) affecting REST API endpoints
- Enhanced post-quantum cryptography support for X.509 certificate validation
Performance Optimizations
- 25% throughput increase for 100Gbps interfaces via SP5 security processor optimizations
- Reduced HA cluster failover latency to <50ms (previously 150ms)
- Extended thermal tolerance to 45°C ambient temperature operations
Protocol & Standards Compliance
- Full TLS 1.3 inspection with hybrid quantum-safe cipher suites
- Extended HTTP/3 (QUIC) application control granularity
- FIPS 140-3 Level 4 certification for cryptographic modules
