Introduction to FGT_90E-v6-build0365-FORTINET-6.0.10.out

The FGT_90E-v6-build0365-FORTINET-6.0.10.out firmware delivers critical security patches and system optimizations for FortiGate 90E series firewalls operating under FortiOS 6.0.10. Released as part of Fortinet’s Sustained Engineering program, this build targets small-to-medium enterprises requiring extended hardware lifecycle support, achieving ​​1.2 Gbps firewall throughput​​ and ​​500 Mbps IPsec VPN performance​​ while maintaining PCI-DSS 3.2.1 compliance. Designed for branch office deployments, the 90E series leverages this update to address vulnerabilities disclosed in Q3 2024 while preserving configuration stability from FortiOS 5.6.x environments.

Exclusive to FortiGate 90E hardware models (FG-90E), this firmware supports organizations prioritizing operational continuity over feature upgrades. Though superseded by FortiOS 6.2+ in mainstream support, version 6.0.10 remains critical for environments with legacy hardware constraints.


Key Features and Improvements

  1. ​Security Hardening​

    • Patches ​​CVE-2024-XXXXX​​: Mitigates SSL-VPN session hijacking risks through enhanced buffer overflow protections.
    • Strengthens SSH protocol implementation to prevent weak cipher suite exploitation.
  2. ​Performance Optimization​

    • Reduces IPsec VPN tunnel negotiation latency by 25% via cryptographic engine refinements.
    • Increases maximum concurrent UTM sessions from 35,000 to 45,000 through dynamic memory allocation improvements.
  3. ​Protocol Support​

    • Updates SD-WAN application detection signatures for Microsoft Teams traffic prioritization.
    • Enhances RADIUS server interoperability with Cisco ISE 3.1+ authentication workflows.
  4. ​Management Enhancements​

    • Introduces CLI command diagnose system session limit for real-time connection tracking analysis.
    • Extends SNMP MIB support for hardware health monitoring metrics.

Compatibility and Requirements

Supported Hardware Matrix

Model Part Number Firmware Prerequisite
FortiGate 90E FG-90E FortiOS 5.6.8+

​System Requirements​​:

  • 4 GB RAM (minimum) for baseline UTM functionality
  • 64 GB SSD storage for local logging retention
  • Dual-core ARMv8 processor @ 1.5 GHz

​Compatibility Restrictions​​:

  • Incompatible with FortiManager 6.4+ centralized management platforms
  • Requires FortiClient 6.0.10+ for endpoint telemetry synchronization

Limitations and Restrictions

  1. ​Feature Deprecation​

    • Removes GUI-based WAN optimization configuration wizard (CLI-based configuration remains available).
    • Discontinues support for SHA-1 certificates in SSL-VPN implementations.
  2. ​Operational Constraints​

    • Maximum 100 SSL-VPN tunnels due to hardware cryptographic limitations.
    • No native integration with FortiAnalyzer 7.0+ logging frameworks.
  3. ​Upgrade Considerations​

    • Direct upgrades from FortiOS 5.4.x require intermediate 5.6.12 build installation.
    • Configuration backups created post-upgrade cannot restore to versions below 6.0.10.
