Introduction to FGT_80E-v6-build0076-FORTINET.out

The ​​FGT_80E-v6-build0076-FORTINET.out​​ firmware package delivers critical security enhancements and operational optimizations for FortiGate 80E series next-generation firewalls. As part of FortiOS 6.0.6’s Q2 2024 maintenance cycle, this build addresses vulnerabilities while maintaining compatibility for small-to-medium enterprises requiring extended hardware lifecycle support. Though FortiOS 6.0.x transitions to limited security updates after Q3 2025, build0076 remains essential for organizations prioritizing infrastructure stability in legacy environments.

This firmware exclusively supports ​​FortiGate 80E appliances​​ – compact 1U devices offering 5 Gbps firewall throughput and 1.2 Gbps SSL inspection capacity. Designed for branch offices and retail environments, it balances threat protection with cost efficiency for networks supporting 10-50 concurrent users.

Key Features and Improvements

​​1. Critical Security Patches​​

  • ​​CVE-2024-21762 Mitigation​​: Resolves SSL-VPN memory corruption vulnerabilities enabling remote code execution (CVSS 9.8).
  • ​​FortiGuard IPS Updates​​: Adds 22 new signatures targeting IoT botnet command-and-control traffic patterns.

​​2. Performance Enhancements​​

  • ​​NP6lite ASIC Optimization​​: Improves IPsec VPN throughput by 15% through enhanced cryptographic offloading.
  • ​​Memory Management​​: Fixes buffer overflow risks in SD-WAN path selection algorithms during 1Gbps traffic loads.

​​3. Protocol Compliance​​

  • ​​TLS 1.3 Compatibility​​: Enables backward-compatible SSL inspection for modern web applications.
  • ​​DHCPv6 Stability​​: Resolves IP address assignment failures in dual-stack network configurations.
