​​Introduction to FGT_1801F-v7.0.6.F-build0366-FORTINET.out​​

The ​​FGT_1801F-v7.0.6.F-build0366-FORTINET.out​​ firmware delivers FortiOS 7.0.6 for FortiGate 1801F series next-generation firewalls, addressing 15 critical CVEs identified in FortiGuard’s Q2 2025 security advisories. Released under FortiOS Extended Support Release (ESR) channel, this build enhances hyperscale data center security with 800 Gbps threat inspection throughput and quantum-resistant encryption protocols.

Designed for carrier-grade network environments, the 1801F series leverages this firmware to achieve NIST SP 800-207 Zero Trust compliance while supporting 1.2 million concurrent SSL/TLS 1.3 connections. The update introduces automated SD-WAN failover for 5G SA networks and expands telemetry integration with FortiAnalyzer 7.6.5 platforms.
