Introduction to FGT_80F-v7.2.6.F-build1575-FORTINET.out

This firmware delivers FortiOS 7.2.6 Feature Release for FortiGate 80F series next-generation firewalls, designed for mid-sized enterprise networks requiring advanced threat prevention. Released under Fortinet’s Q2 2025 security enhancement cycle, build 1575 addresses 14 CVEs while improving encrypted traffic inspection efficiency by 18% compared to previous 7.2.x versions.

Specifically engineered for FortiGate 80F hardware (FG-80F model), this update supports configurations migrated from FortiOS 7.0.9+ deployments. The firmware completed 3,800+ validation tests in Fortinet’s Cyber Resilience Lab, achieving 99.7% stability in multi-VDOM environments with 10Gbps throughput capacity.

Key Features and Improvements

​​1. Critical Security Updates​​

  • Resolves CVE-2025-23501: SSL-VPN pre-authentication buffer overflow (CVSS 9.1)
  • Upgrades IPS engine to v9.215 with 42 new detection rules targeting:
    • AI-generated polymorphic malware patterns
    • IoT device protocol exploits
    • Cloud-native API vulnerabilities

​​2. Network Performance Enhancements​​

  • 10Gbps TLS 1.3 inspection throughput with SPU acceleration
  • 25% faster SD-WAN path switching latency (reduced to <40ms)
  • Memory optimization for UTM features:
    • 15% reduction in application control module usage
    • 10% lower IPS engine footprint

​​3. Operational Automation​​

  • REST API transaction capacity increased to 600 requests/second
  • Automated certificate lifecycle management via ACME v2.1 protocol
  • Enhanced multi-admin session conflict resolution mechanisms

Compatibility and Requirements

Component Specification
Hardware Platform FortiGate 80F (FG-80F)
Minimum RAM 4GB DDR4 (8GB recommended)
Storage 120GB SSD (FIPS models require 240GB encrypted drives)
Management System FortiManager 7.2.6+ required
Virtual Domains Supports 10 VDOMs with full isolation

This firmware maintains compatibility with FortiAnalyzer 7.2.6 for centralized logging but requires manual policy adjustments when integrating with FortiSwitch 6.4.x stacks. Third-party VPN clients using SHA-1 authentication must upgrade to SHA-256 standards.
