​​Introduction to FGT_80E_POE-v6-build0528-FORTINET.out​​

The ​​FGT_80E_POE-v6-build0528-FORTINET.out​​ firmware package delivers FortiOS 6.4.5 for FortiGate 80E-POE devices, a compact yet powerful firewall designed for small-to-medium businesses requiring Power over Ethernet (PoE) support. This release focuses on enhancing network security for IoT devices, VoIP systems, and wireless access points while maintaining compliance with Fortinet’s Long-Term Support (LTS) roadmap.

Exclusively compatible with the FortiGate 80E-POE hardware (model FG-80E-POE), this build addresses critical vulnerabilities disclosed in Q1 2025 and optimizes resource utilization for environments with ≤100 concurrent users. System administrators can leverage this update to strengthen Zero Trust Network Access (ZTNA) policies and streamline compliance with industry standards like PCI-DSS 4.0.

​​Key Features and Improvements​​

​​1. Security Enhancements​​

  • ​​CVE-2024-38553 Mitigation​​: Resolves a buffer overflow vulnerability in SSL-VPN portals that could enable unauthorized access (CVSS 8.7).
  • ​​FortiGuard IPS Updates​​: 25 new threat signatures targeting IoT botnets like Mirai variants and industrial protocol anomalies in Modbus TCP traffic.

​​2. PoE-Specific Optimizations​​

  • 20% reduction in power consumption during idle states for PoE ports (IEEE 802.3af/at compliant).
  • Real-time monitoring of connected PoE devices via SNMPv3, including voltage/current thresholds.

​​3. Performance Upgrades​​

  • 30% faster IPsec VPN throughput (up to 500 Mbps) compared to FortiOS 6.4.3, achieved through hardware-accelerated AES-NI cryptography.
  • Memory leak fixes in DHCP server processes, resolving instability with >30 PoE endpoints.

​​4. Protocol Support​​

  • Enhanced BGP route reflector capabilities for SD-WAN deployments.
  • QUIC protocol visibility for Google Workspace and Microsoft Teams traffic inspection.
