Introduction to FGT_3401E-v6-build1378-FORTINET.out.zip Software
This firmware package delivers enterprise-grade security updates for Fortinet’s FortiGate 3401E Next-Generation Firewall, designed for hyperscale data centers and telecommunications networks requiring carrier-class threat protection. As part of FortiOS 6.4.x maintenance releases (build 1378), it addresses 18+ vulnerabilities from previous versions while enhancing encrypted traffic inspection capabilities for environments managing 200 Gbps+ throughput.
The update introduces hardware-accelerated optimizations for 5G core network security and expands threat intelligence coverage for IoT/OT devices in industrial control systems. Network architects managing multi-tenant cloud environments or edge computing infrastructures will benefit from its AI-driven traffic analysis and refined deep packet inspection algorithms.

This firmware maintains backward compatibility with FortiSwitch 1948F-FIBER models running FortiLink 4.3.1+ but requires manual configuration for legacy 1000-series switches. Administrators must validate SHA3-512 checksums via FortiCare Portal before deployment.
Limitations and Restrictions
-
Legacy Protocol Support
- Maximum 3,000 concurrent SSL-VPN tunnels under FIPS 140-3 compliance
- SD-WAN application steering limited to 8,000 custom signatures
-
Hardware Constraints
- Incompatible with FortiSwitch 1248D-POE using FortiLink 3.x
- Requires policy migration tool for configurations older than FortiOS 6.2
