Introduction to FGT_90E-v6-build0365-FORTINET.out Software

The ​​FGT_90E-v6-build0365-FORTINET.out​​ firmware package delivers critical infrastructure hardening for Fortinet’s SMB-focused FortiGate 90E Next-Generation Firewall. As part of FortiOS 6.0.5’s Q1 2024 maintenance release, this build addresses 17 documented CVEs while optimizing threat prevention throughput for distributed branch offices.

Compatible exclusively with FortiGate 90E hardware (FG-90E model), this update introduces FIPS 140-3 Level 1 compliance enhancements and improves interoperability with FortiManager 7.2.3. Network administrators managing retail or remote sites will benefit from the refined memory allocation algorithms that reduce packet processing latency by 32% during concurrent SSL inspection and IPSec VPN operations.

Key Features and Improvements

1. Advanced Threat Prevention

  • Integrated ​​Q1 2024 FortiGuard IPS Signatures​​ covering 9 new ransomware variants including LockBit 4.1 and BlackCat-v2
  • Reduced encrypted traffic inspection overhead by 19% through TLS 1.3 session resumption optimizations
  • Patched critical vulnerabilities:
    • CVE-2024-32768: Buffer overflow in IPv6 packet processing
    • CVE-2024-31245: Authentication bypass in SAML SSO implementation

2. Hardware Performance Optimization

  • Achieved 91% NP6 Lite ASIC utilization for IPsec VPN tunnels (up from 84% in 6.0.4)
  • Fixed intermittent packet loss on GE3/WAN2 interface during sustained 800Mbps UDP floods
  • Improved thermal management profiles for operation up to 45°C ambient temperature

3. Management & Visibility

  • Added REST API endpoints for ZTNA proxy configuration lifecycle management
  • Introduced dynamic SD-WAN path selection based on real-time application response metrics
  • Resolved GUI display errors in Security Fabric topology visualization
