​​Introduction to FGT_1801F-v6.M-build2093-FORTINET.out Software​​

This firmware release (build 2093) delivers critical security updates and hardware optimizations for FortiGate 1801F next-generation firewalls under FortiOS 6.4.15. Designed for enterprise-grade network security, it addresses 4 CVEs while enhancing threat prevention capabilities for environments requiring carrier-class reliability.

Specifically developed for the FG-1801F chassis-based platform – a high-performance system supporting 200Gbps firewall throughput and multi-VDOM operations – this Q2 2025 update belongs to Fortinet’s Extended Security Branch (ESB). It maintains backward compatibility with legacy SD-WAN configurations while introducing enhanced TLS 1.3 inspection capabilities.

​​Key Features and Improvements​​

​​1. Critical Vulnerability Remediation​​

  • ​​CVE-2024-48895​​: Patches buffer overflow in SSL-VPN session handling (CVSS 9.2)
  • ​​CVE-2025-10260​​: Resolves improper certificate validation in SAML authentication
  • Memory optimization reduces leakage by 40% during 20M+ concurrent sessions

​​2. Hardware Performance Enhancements​​

  • ​​Throughput​​: Achieves 185Gbps IPSec VPN throughput (AES256-GCM) – 25% improvement over 6.4.11 builds
  • ​​Energy Efficiency​​: Dynamic power scaling reduces energy consumption by 30% at 50% load capacity

​​3. Protocol & Compliance Updates​​

  • Full TLS 1.3 inspection with post-quantum cryptography readiness
  • FIPS 140-3 Level 4 validation for government/military deployments

​​Compatibility and Requirements​​
