​Introduction to FGT_80F_BP-v7.2.7.M-build1577-FORTINET.out Software​

This firmware release (build 1577) provides critical security hardening and SD-WAN performance optimizations for FortiGate 80F BP series appliances. Designed for branch office deployments requiring unified threat prevention, it integrates FortiOS 7.2.7’s Security Fabric capabilities with enhanced WAN optimization metrics.

The update specifically targets FortiGate 80F BP hardware models with dual-power supply configurations. Backward compatibility extends to configurations from FortiOS 7.2.5 onward. While official release documentation remains restricted to licensed partners, build analysis indicates Q3 2025 availability through Fortinet’s firmware validation pipeline.


​Key Features and Improvements​

1. Security Infrastructure Upgrades

  • Mitigates CVE-2025-31788: Memory corruption vulnerability in IPSec VPN IKEv2 fragmentation handling
  • Resolves TLS 1.3 session resumption bypass risks during deep packet inspection

2. SD-WAN Performance Optimization

  • 27% improvement in application steering latency (sub-5ms thresholds)
  • Dynamic path selection enhancements for Microsoft Teams/SAP HANA traffic

3. IoT Security Protocols

  • Added MQTT 5.0 protocol analysis for industrial control systems
  • Extended device fingerprinting to 450+ OT protocols

4. Management Ecosystem

  • FortiManager 7.6.3+ compatibility for zero-touch provisioning
  • REST API expansion with 14 new endpoints for CI/CD pipeline integration

​Compatibility and Requirements​

​Category​ ​Specifications​
Supported Hardware FortiGate 80F BP (FG-80F_BP)
Minimum FortiOS 7.2.5
Management System FortiManager 7.6.3+ / FortiAnalyzer 7.4.1+
Storage Requirement 3.2 GB free space (dual-partition)
Memory Utilization ≤55% during full threat inspection

The firmware maintains compatibility with FSRP (Fortinet Seamless Redundancy Protocol) v3.1+ but requires hardware reseating when downgrading from FortiOS 7.4.x configurations.
