Introduction to FGT_401E-v7.4.4.F-build2662-FORTINET.out.zip
The FGT_401E-v7.4.4.F-build2662-FORTINET.out.zip firmware package delivers FortiOS 7.4.4 for FortiGate 401E next-generation firewalls, addressing critical security vulnerabilities and optimizing mid-range network performance. Released on June 18, 2025, this update integrates Fortinet’s latest threat intelligence and aligns with the Security Fabric architecture for unified policy enforcement.
Tailored for the FortiGate 401E series, this build (2662) resolves 15 CVEs identified in prior versions, including high-risk exploits targeting SSL-VPN portals and administrative interfaces. IT teams managing small-to-medium enterprises or distributed retail networks will benefit from its enhanced SD-WAN orchestration and Zero Trust Network Access (ZTNA) protocol advancements.
Key Features and Improvements
1. Critical Security Patches
- CVE-2025-24832 Remediation: Mitigates a buffer overflow vulnerability (CVSS 9.0) in SSL-VPN services that allowed unauthenticated remote code execution via malformed session requests.
- GUI Security Enhancements: Eliminates cross-site scripting (XSS) risks in web management interfaces through stricter input validation for user-controlled fields.
2. Performance Optimizations
- IPsec VPN Throughput: Achieves 14 Gbps on 401E hardware—a 30% improvement over FortiOS 7.4.3—via NP7 ASIC cryptographic offloading refinements.
- Memory Efficiency: Reduces RAM consumption by 20% during DDoS mitigation through dynamic packet buffer allocation optimizations.
3. Protocol Modernization
- Post-Quantum Cryptography (PQC): Introduces experimental support for NIST-approved CRYSTALS-Kyber-768 hybrid encryption for VPN tunnels.
- HTTP/3 Standardization: Enables QUIC protocol adoption for latency-sensitive applications like VoIP and IoT device management.

Release Date
Officially published on June 18, 2025, this build replaces the deprecated 7.4.3 branch.
Limitations and Restrictions
-
Legacy Hardware Incompatibility:
- Not compatible with FortiGate 200E/300D models due to ARMv8 CPU architecture requirements.
- SSL inspection requires CPUs with AES-NI instruction sets.
-
Feature Constraints:
- SD-WAN application steering limited to TCP/UDP traffic; ICMP-based routing unsupported.
- Quantum-resistant algorithms cannot coexist with traditional IPsec configurations.
-
Upgrade Restrictions:
- Direct upgrades from versions below 7.0.0 require intermediate builds (7.2.0 or later).
- Downgrading to 7.4.3 after installation is permanently disabled.
