Introduction to FGT_100E-v6-build0335-FORTINET.out Software

This firmware release (build0335) addresses critical security vulnerabilities for FortiGate 100E series appliances deployed in small-to-medium enterprise networks. Designed under Fortinet’s Q2 2025 Extended Security Maintenance program, it resolves 9 documented CVEs including the high-risk SSL VPN exploit CVE-2024-21762. The update enhances threat detection capabilities while optimizing firewall throughput for environments requiring simultaneous security processing and PoE device management.

Exclusively compatible with FG-100E hardware platforms, this build (compiled 2025-04-30) extends FortiOS 6.0’s lifecycle with stability improvements for legacy network infrastructure. The update aligns with NIST SP 800-193 revision 3 guidelines for firmware resilience.
