Introduction to FGT_201E-v6-build1175-FORTINET.out
This firmware release addresses critical network vulnerabilities for FortiGate 201E enterprise firewalls deployed in medium-sized business environments requiring uninterrupted security operations. Validated under FortiOS v6.4.10’s Extended Support Track, build 1175 resolves 7 documented CVEs while maintaining compatibility with SD-WAN and multi-VDOM configurations.
Specifically designed for FortiGate 201E (FG-201E) appliances, this update is mandatory for organizations handling PCI-DSS 3.2.1-compliant transactions or operating under HIPAA security rules. The release aligns with Fortinet’s Q2 2025 firmware lifecycle schedule for legacy hardware platforms.
