Introduction to FGT_401E-v6-build1723-FORTINET.out.zip Software
This firmware package delivers critical infrastructure protection for FortiGate 401E series next-generation firewalls, designed for mid-sized enterprises requiring advanced threat prevention with SSL/TLS inspection capabilities. The v6-build1723 iteration represents a cumulative security update within FortiOS 6.4 extended support branch, optimized for networks handling 10Gbps+ encrypted traffic through NP6 ASIC acceleration.
Compatible with FortiGate 401E/400E hardware appliances, this build addresses stability concerns in high-availability cluster configurations while maintaining backward compatibility with FortiManager 7.0.3+ for centralized policy management. Though official release notes don’t specify an exact publication date, build sequence analysis aligns with Fortinet’s Q1 2024 security patch cycle.

Compatibility and Requirements
| Supported Hardware | Minimum Requirements | Incompatible Versions |
|---|---|---|
| FortiGate 401E | 8GB RAM | FortiOS 7.x branches |
| FortiGate 400E | 128GB SSD | FGT_400F-v7.x builds |
| NP6 processor |
This firmware requires FortiManager 7.0.3+ for full feature synchronization and FortiAnalyzer 7.2.1+ for log correlation. The build cannot be deployed on devices with NP6-Lite chipsets due to hardware acceleration dependencies.
