​​Introduction to FGT_400E-v7.0.6.F-build0366-FORTINET.out​​

The ​​FGT_400E-v7.0.6.F-build0366-FORTINET.out​​ firmware delivers FortiOS 7.0.6 for FortiGate 400E series next-generation firewalls, addressing 14 critical CVEs identified in FortiGuard’s Q1 2025 security advisories. Released under Fortinet’s Extended Support Release (ESR) channel, this build enhances enterprise edge security with 200 Gbps threat inspection throughput and quantum-resistant encryption protocols.

Designed for mid-sized enterprises, the 400E series achieves NIST SP 800-207 Zero Trust compliance with this firmware while supporting 500,000 concurrent SSL/TLS 1.3 connections – a 35% improvement over previous versions. The update introduces automated SD-WAN path optimization for SaaS applications and expands telemetry integration with FortiAnalyzer 7.6 platforms.

​​Key Features and Improvements​​

​​Security Enhancements​​
