1. Introduction to FGT_3100D-v6.M-build2030-FORTINET.out

This firmware package delivers FortiOS 6.4.11 for FortiGate 3100D series next-generation firewalls, designed for enterprise data centers requiring extended security maintenance under Fortinet’s Critical Vulnerability Response program. Released in Q3 2024 as build 2030, this update focuses on maintaining operational continuity for NIST 800-53 compliant environments while enhancing backward compatibility with hybrid cloud architectures.

Compatible with FG-3100D hardware in clustered deployments, the software provides critical security hardening for financial institutions and healthcare networks requiring PCI-DSS 4.0 compliance. It serves as the final firmware iteration before FortiOS 7.x migration for this hardware series, prioritizing stability over feature expansion.
