Introduction to FGT_2000E-v6-build0163-FORTINET.out Software

This firmware package delivers FortiOS 6.4.15 for FortiGate 2000E hyperscale firewalls, designed to address critical vulnerabilities in enterprise network security while optimizing performance for high-density data center environments. As a maintenance release, it focuses on stability improvements for organizations requiring 800Gbps+ threat inspection throughput with multi-terabit routing capabilities.

Compatible exclusively with FortiGate 2000E chassis manufactured after Q4 2023, this build supports octa NP7XLite security processors and hyperscale SSL inspection workloads. The firmware became generally available on March 15, 2025, following validation with major cloud service providers and SDN ecosystems.
