Introduction to FGT_3800D-v7.0.2-build0234-FORTINET.out

This firmware release (FGT_3800D-v7.0.2-build0234-FORTINET.out) provides critical security hardening and performance enhancements for FortiGate 3800D enterprise firewalls, targeting organizations requiring robust network segmentation and threat prevention capabilities. As part of FortiOS 7.0.2’s Extended Security Maintenance program, it resolves 8 documented CVEs while optimizing NP6 ASIC utilization for high-density traffic inspection.

Validated exclusively for FortiGate 3800D hardware (SKU FG-3800D-POE-860-24), this build0234 revision addresses vulnerabilities in SSL-VPN services and improves interoperability with 802.3at-compliant PoE devices. Released on March 15, 2025, it requires 8GB DDR4 RAM and FortiManager 7.6.1+ for centralized management.
