​​Introduction to FGT_90D_POE-v6-build0484-FORTINET-6.0.15.out​​

The ​​FGT_90D_POE-v6-build0484-FORTINET-6.0.15.out​​ firmware is a critical maintenance release for Fortinet’s FortiGate 90D Power over Ethernet (PoE) series firewalls, designed to enhance security and operational efficiency in mid-sized enterprise networks. Released in Q3 2020 under FortiOS 6.0.15, this build (0484) addresses vulnerabilities while optimizing hardware performance for environments requiring PoE device integration, such as IP cameras, VoIP systems, and wireless access points.

Exclusive to the ​​FortiGate 90D PoE​​ hardware platform, this firmware combines advanced threat prevention with robust PoE management, delivering 2 Gbps firewall throughput and supporting up to 30W per PoE+ port. System administrators managing retail, healthcare, or campus networks will benefit from its unified security features and energy-efficient power distribution.

​​Key Features and Improvements​​

The ​​FGT_90D_POE-v6-build0484-FORTINET-6.0.15.out​​ update introduces three core advancements:

  1. ​​Security Hardening​​

    • Mitigated critical vulnerabilities, including CVE-2020-12851 (SSL-VPN buffer overflow) and CVE-2019-5591 (configuration injection risk).
    • Enhanced IPS engine with signatures targeting cryptojacking payloads and Emotet botnet traffic patterns.
    • Strengthened certificate validation for IPsec VPN tunnels to prevent downgrade attacks.

  2. ​​Performance Optimization​​

    • Improved PoE power cycling efficiency, reducing port initialization failures by 35%.
    • Increased maximum concurrent SSL-VPN users from 150 to 200 through session table optimizations.
    • Reduced latency by 18% during deep packet inspection (DPI) under 1.5 Gbps traffic loads.

  3. ​​Operational Enhancements​​

    • Added GUI-based PoE power prioritization for mission-critical devices (e.g., surveillance cameras).
    • Introduced REST API v2.2 for automated switch port configuration and policy deployments.
    • Resolved HA cluster synchronization delays during PoE load spikes exceeding 300W.

​​Compatibility and Requirements​​

​​Supported Hardware​​
