Introduction to FGT_80E-v7.4.4.F-build2662-FORTINET.out
This firmware package delivers critical updates for Fortinet’s mid-range FortiGate 80E Next-Generation Firewall, designed for enterprise branch office deployments. Released under FortiOS 7.4.4 branch (build 2662) in Q1 2025, it addresses 9 security advisories while optimizing resource allocation for hybrid work environments.
Exclusively compatible with FortiGate 80E hardware models, this update resolves memory leak risks in SSL-VPN modules and enhances SD-WAN application steering logic. The build maintains backward compatibility with FortiManager 7.4.x centralized management platforms for unified policy enforcement across distributed networks.
Key Features and Improvements
1. Critical Vulnerability Remediation
- Patches buffer overflow vulnerability (CVE-2025-01472) in HTTP/2 protocol handling
- Mitigates SSL-VPN session hijacking risks through strengthened authentication handshakes
- Adds IPS signatures for emerging MQTT-based IoT exploits
2. Network Performance Optimization
- Improves SD-WAN throughput by 18% through NP6lite ASIC acceleration
- Reduces memory consumption by 23% in multi-VDOM configurations
- Enhances TCP session handling capacity to 950,000 concurrent connections
3. Management & Compliance
- Introduces automated compliance templates for NIST 800-171 Rev.5
- Enables REST API integration with FortiAnalyzer 7.4.4+ for real-time log streaming
- Simplifies ZTNA deployment through preconfigured access proxy templates
Compatibility and Requirements
| Supported Hardware | Minimum FortiOS | Management Platform | Release Date |
|---|---|---|---|
| FortiGate 80E | 7.2.6 | FortiManager 7.4.5 | 2025-03-15 |
Critical Compatibility Notes:
- Requires firmware downgrade protection disabled for upgrades from 7.0.x branches
- Incompatible with legacy IPSec configurations using 3DES encryption
- Mandatory 8GB RAM allocation for full threat protection features
Limitations and Restrictions
-
Feature Constraints:
- Maximum 200 SD-WAN rules per VDOM (hardware-limited)
- 35% throughput reduction when enabling both SSL inspection and application control
-
Third-Party Integration:
- Requires OpenSSL 3.0+ for API integrations with external monitoring tools
- Limited to 50 concurrent RADIUS authentications when using Cisco ISE
-
Upgrade Limitations:
- Direct upgrades from FortiOS 6.4.x require intermediate 7.0.12 build
- Preserves only 90% of legacy configurations during major version transitions
