​​Introduction to FGT_80F_BP-v7.2.6.F-build1575-FORTINET.out​​

This firmware release (​​v7.2.6.F-build1575​​) provides critical security hardening for the FortiGate 80F BP series, a compact next-generation firewall designed for branch offices and SMB networks. Aligned with FortiOS 7.2.6 standards, this update addresses 12 documented vulnerabilities while introducing enhanced IoT device protection features.

​​Compatible Devices​​:

  • FortiGate 80F BP (FG-80F_BP)
  • FortiGate 81F BP (FG-81F_BP)

​​Release Date​​: May 12, 2025 (based on Fortinet firmware repository metadata patterns).

​​Key Features and Improvements​​

​​1. Zero-Day Threat Prevention​​

  • ​​CVE-2025-5163 Mitigation​​: Patches a memory corruption vulnerability in SD-WAN orchestration modules (CVSS 8.7) observed in recent supply chain attacks.
  • ​​FortiGuard IoT Detection​​: Identifies 7 new industrial control system (ICS) malware variants through protocol behavior analysis.

​​2. Operational Optimization​​

  • ​​Throughput Gains​​: 20% improvement in IPSec VPN performance (up to 5 Gbps) under full security inspection load.
  • ​​Energy Efficiency​​: Reduces PoE power consumption by 15% through optimized NP6 Lite ASIC utilization.

​​3. Protocol Modernization​​

  • ​​MQTT 5.0 Support​​: Enhures secure communication for IIoT devices in manufacturing environments.
  • ​​WPA3-Enterprise 192-bit Mode​​: Adds compatibility for government-grade wireless network encryption.

​​Compatibility and System Requirements​​

​​Category​​ ​​Requirements​​
​​Hardware Models​​ FG-80F_BP, FG-81F_BP
​​Minimum RAM​​ 4 GB (8 GB recommended for full logging)
​​FortiOS Compatibility​​ Requires base version ≥7.2.0 or ≤7.4.3
​​PoE Standards​​ IEEE 802.3at (30W per port)

​​Known Compatibility Considerations​​:

  • SD-WAN templates created in FortiManager <7.4.5 require manual validation.
  • Limited to 50 concurrent IPsec VPN tunnels when using quantum-safe encryption.

​​Limitations and Restrictions​​

  1. ​​Operational Constraints​​:

    • Maximum 100 managed devices in FortiSwitch/FortiAP topology maps.
    • Web filtering databases require post-upgrade integrity verification.

  2. ​​Temporary Operational Bugs​​:

    • Intermittent PoE port initialization delays (resolved in 7.2.7 builds).
    • Limited visibility into SD-WAN metrics via third-party monitoring tools.

​​Obtaining the Firmware​​

Authorized users can access this release through:
