Introduction to FGT_3300E-v6-build6669-FORTINET.out
This firmware release (6.0.18 build6669) delivers enterprise-grade security hardening and network performance enhancements for FortiGate 3300E next-generation firewalls, specifically engineered for hyperscale data centers and mission-critical infrastructure. As part of FortiOS 6.0 Extended Support Release (ESR), it addresses 3 critical CVEs while maintaining backward compatibility with legacy industrial control systems (ICS) and SCADA architectures.
Exclusively compatible with FortiGate 3300E hardware models (FG-3300E), this update aligns with NIST 800-53 Rev.5 and ISO 27001:2022 compliance requirements. Though the official release date is unpublished, Fortinet’s ESR lifecycle confirms active maintenance for FortiOS 6.0.x until Q2 2027.
