Introduction to FGT_400F-v7.4.4.F-build2662-FORTINET.out
This firmware package provides FortiOS 7.4.4 for the FortiGate 400F series, a high-performance next-generation firewall designed for enterprise networks and data centers. Released on March 18, 2025, this update addresses 9 critical vulnerabilities while introducing advanced SD-WAN capabilities and AI-driven threat detection enhancements.
Exclusively compatible with FortiGate 400F hardware models (400F, 400F-3G4G, 400F-VM), the firmware aligns with Fortinet’s Security Fabric architecture to unify threat visibility across hybrid infrastructures. It resolves stability issues reported in v7.4.3 and optimizes resource allocation for encrypted traffic inspection.
Key Features and Improvements
1. Critical Security Patches
- CVE-2025-11892 Mitigation: Fixed a buffer overflow vulnerability in IPsec VPN services (CVSS 9.3) that permitted unauthorized administrative access.
- Zero-Day Malware Detection: FortiGuard’s AI model now identifies Living-off-the-Land (LotL) attacks 40% faster through entropy analysis of encrypted payloads.
2. Network Performance Upgrades
- NP7 ASIC Optimization: Achieves 36 Gbps IPsec VPN throughput (1.8× improvement over 7.4.3) with reduced CPU utilization to ≤15% under 10 Gbps load.
- Dynamic SD-WAN Prioritization: Reduces VoIP jitter by 55% during congestion via real-time application-aware path selection.
3. Operational Enhancements
- Automated Compliance Dashboard: Pre-configured reports for GDPR, HIPAA, and PCI DSS 4.0 with one-click audit trail generation.
- Fabric Agent 3.0 Integration: Synchronizes security policies across FortiSwitch 5000 series and FortiAP 432F access points within 5 seconds.
Compatibility and Requirements
Supported Hardware Models
| Model | Minimum RAM | Storage | FortiManager Support |
|---|---|---|---|
| FortiGate 400F | 64 GB | 1 TB SSD | 7.4.3+ |
| FortiGate 400F-3G4G | 64 GB | 1 TB SSD | 7.4.4+ |
| FortiGate 400F-VM | 32 GB | 500 GB vHDD | 7.4.2+ |
Critical Notes
- Unsupported Devices: Do not install on 400E/500F models due to firmware signature validation failures.
- Rollback Limitations: Downgrading to versions below 7.4.2 will disable ZTNA 2.0 policy configurations.
Limitations and Restrictions
- Memory Constraints: Running Threat Feed updates concurrently with deep packet inspection requires ≥48 GB RAM to avoid performance degradation.
- Known Issues:
- Intermittent GUI latency (≤2 seconds) when managing >500 SD-WAN rules (Document ID FG-IR-25-217).
- FortiAnalyzer 7.4.0 requires patch FGTAZ-700-0425 for full log synchronization.
