Introduction to FGT_80F-v6-build1911-FORTINET.out.zip Software
This firmware package delivers enterprise-grade security enhancements for FortiGate 80F series next-generation firewalls, designed for small-to-medium businesses requiring robust network protection with SSL/TLS inspection capabilities. As part of FortiOS 6.4.15 extended support cycle (build1911), this release focuses on operational stability for networks handling 5Gbps+ encrypted traffic through NP6 Lite ASIC hardware acceleration.
Compatible exclusively with FortiGate 80F/81F hardware appliances, this update resolves critical vulnerabilities in multi-WAN configurations while maintaining backward compatibility with FortiManager 7.0.3+ for centralized policy management. The build sequence aligns with Fortinet’s Q1 2025 security maintenance schedule, addressing critical CVEs disclosed in recent security bulletins.
Key Features and Improvements
- Critical Security Patches
- Addresses 3 high-risk CVEs including CVE-2024-21762 (SSL VPN memory corruption)
- Mitigates buffer overflow vulnerabilities affecting IPS engine performance under 10k concurrent sessions
- Performance Optimization
- Achieves 7.5Gbps threat prevention throughput with full UTM inspection enabled
- Reduces HA cluster synchronization latency by 35% during failover events
- Protocol Modernization
- Supports RFC 9440 for quantum-resistant cryptographic handshake protocols
- Implements HTTP/3 traffic classification via enhanced QUIC protocol analysis
- Management Upgrades
- Introduces REST API endpoints for SD-WAN application routing configurations
- Enhances FortiAnalyzer log processing efficiency by 30% through optimized compression algorithms
Compatibility and Requirements
| Supported Hardware | Minimum Requirements | Incompatible Versions |
|---|---|---|
| FortiGate 80F | 4GB RAM | FortiOS 7.x branches |
| FortiGate 81F | 64GB SSD | FGT_80G-v7.x builds |
| NP6 Lite processor |
This firmware requires FortiManager 7.0.3+ for policy synchronization and FortiAnalyzer 7.2.1+ for log aggregation. Installation on devices with NP4 processors is unsupported due to hardware acceleration limitations.
