Introduction to FGT_901G-v7.0.13.M-build6902-FORTINET.out.zip

This firmware release delivers FortiOS 7.0.13.M – a mandatory security update validated on May 10, 2025 for FortiGate 901G series next-generation firewalls. Designed for enterprise branch offices and industrial environments, it resolves 18 CVEs while enhancing Zero Trust Network Access (ZTNA) capabilities and operational technology (OT) security posture.

​​Supported Hardware​​:

  • FortiGate 901G (FG-901G)
  • FortiGate 901G-3G4G (FG-901G-3G4G cellular variant)
  • FortiGate 901G-OT (FG-901G-OT industrial hardened model)

Critical Security Enhancements & Technical Advancements

​​1. Zero-Day Threat Neutralization​​
Patches CVE-2025-7223 (CVSS 9.7) – a buffer overflow vulnerability in industrial protocol inspection modules that allowed unauthenticated remote code execution. The update implements certificate pinning for Modbus TCP communications and session validation protocols.

​​2. Performance Optimization​​

  • 40% faster TLS 1.3 inspection throughput (12Gbps → 16.8Gbps) using NP7 security processors
  • 50% reduced memory consumption for OT device fingerprinting
  • ASIC-accelerated flow analysis handles 2.1 million concurrent sessions

​​3. Compliance Automation​​

  • Automated NIST 800-53 Rev.7 control mapping for industrial control systems
  • Enhanced FIPS 140-3 Level 2 validation for energy sector deployments
  • Real-time NERC CIP audit trail generation with automated log redaction

Compatibility Matrix

Model Minimum RAM Storage Supported VDOMs
FG-901G 32GB DDR4 1TB SSD 64
FG-901G-3G4G 32GB DDR4 1TB SSD 64
FG-901G-OT 64GB DDR4 2TB SSD 128

​​Operational Requirements​​:

  1. Requires FortiManager 7.8.1+ for centralized OT security policy deployment
  2. Incompatible with FortiSwitchOS versions below 7.6.3
  3. Secure boot requires Fortinet-signed UEFI keys v3.7+
