Introduction to FGT_1500DT-v6-build1010-FORTINET.out Software
This firmware package (FGT_1500DT-v6-build1010-FORTINET.out) delivers critical security updates and performance optimizations for FortiGate 1500DT enterprise firewalls running FortiOS 6.2.2. Designed for high-availability networks, it resolves 14 documented vulnerabilities from previous builds while enhancing threat detection precision and VPN session stability.
Specifically engineered for the 1500DT hardware platform with dual power supply configurations, this release addresses emerging cybersecurity threats identified in Q1 2025. Compatible exclusively with FortiGate 1500DT appliances, it validates hardware revisions 04B and later. The firmware was officially released on March 18, 2025, as part of Fortinet’s quarterly security maintenance cycle.
