​​Introduction to FGT_3601E-v6-build1914-FORTINET.out Software​​

This firmware release (build 1914) is designed for FortiGate 3601E series appliances, targeting enterprise networks requiring high-throughput threat prevention and secure SD-WAN operations. As part of FortiOS v6.4.11 branch updates, it addresses 18 CVEs documented in Fortinet’s Q4 2024 security advisories. The update specifically enhances hardware-accelerated SSL inspection and integrates with FortiManager 7.4.5 for centralized policy management.

Compatible exclusively with FortiGate 3601E hardware (FG-3601E), this build aligns with Fortinet’s lifecycle policy, offering critical security patches until Q3 2027. The “v6” designation confirms compatibility with FortiOS 6.4.x branch, resolving configuration conflicts reported in earlier 6.4.9 deployments.
