Introduction to FGT_4401F-v6-build5868-FORTINET.out Software
This mission-critical firmware package delivers advanced threat prevention enhancements and hardware acceleration optimizations for FortiGate 4401F hyperscale firewalls running FortiOS 6.4.11. Released under Fortinet’s Q1 2025 security maintenance program, build 5868 addresses 15 documented CVEs while introducing hardware-accelerated deep packet inspection capabilities.
Specifically engineered for the FortiGate 4401F platform deployed in carrier-grade networks and financial data centers, this 324MB binary supports direct upgrades from FortiOS 6.4.9 through 6.4.10. The update maintains compatibility with existing SD-WAN and intrusion prevention system (IPS) configurations while implementing new quantum-resistant encryption protocols.

- Active FortiGuard Enterprise Protection subscription
- Disabled HA heartbeat interfaces during cluster upgrades
Limitations and Restrictions
-
Upgrade Path Constraints
Devices running FortiOS 6.2.x must first upgrade to 6.4.9 via build FGT_4401F-v6-build5776-FORTINET.out before applying this update. -
Operational Considerations
- Maximum 85% SSD utilization required for cryptographic verification
- 30% performance degradation when mixing NP6/NP7 ASIC generations
- TLS 1.0/1.1 inspection permanently disabled per PCI DSS 4.1
- Feature Deprecations
- IPSec XAUTH client authentication removed for FIPS 140-3 compliance
- Legacy application control categories discontinued (P2P, gaming, etc.)
