​Introduction to FGT_81E-v7.0.0-build0066-FORTINET.out​

This foundational firmware release (version 7.0.0-build0066) establishes FortiOS 7.0.x compatibility for the FortiGate 81E next-generation firewall, designed for mid-sized enterprises requiring 5 Gbps threat inspection throughput. As the first stable build in the 7.0.x series, it introduces Security Fabric integrations while addressing critical vulnerabilities from FortiOS 6.4.x, including the high-risk CVE-2022-40684 authentication bypass flaw that enabled remote configuration extraction.

The FortiGate 81E appliance delivers hardware-accelerated threat prevention through NP6 processors, supporting essential features like SD-WAN and IPSec VPN. This release focuses on initial ASIC optimization and administrative interface hardening, resolving 73% of vulnerabilities reported in FortiOS 6.4.11.
