Introduction to FGT_1000F-v7.4.4.F-build2662-FORTINET.out

This firmware release (build 2662) delivers hyperscale security updates and infrastructure optimizations for FortiGate 1000F Series next-generation firewalls, engineered for enterprise data centers and cloud service providers requiring terabit-level threat prevention. As part of FortiOS 7.4.4, it addresses 28 documented vulnerabilities while introducing hardware-accelerated zero-trust network access (ZTNA) capabilities for 800Gbps environments.

The software officially supports FortiGate 1000F hardware (FG-1000F) with Security Processor Unit (SPU) 7.0 clusters. Configuration backward compatibility is confirmed for environments running FortiOS 7.2.9 or later through automated migration tools.
