​​Introduction to FGT_3401E-v6-build0387-FORTINET.out Software​​

The FGT_3401E-v6-build0387-FORTINET.out firmware package provides critical updates for Fortinet’s FortiGate 3401E series, a high-performance security appliance designed for large enterprises and data centers. Part of the FortiOS v6.4.x branch, this build addresses 15 CVEs while delivering enterprise-grade threat prevention and encrypted traffic inspection. Compatible with FG-3401E and FG-3401E-Bypass hardware models, it supports hyperscale network architectures requiring multi-tenant segmentation and AI-driven threat analysis.

​​Key Features and Improvements​​

This firmware resolves vulnerabilities including:

  • ​​CVE-2024-48776​​ (CVSS 9.2): SSL-VPN heap overflow via malformed session cookies
  • ​​CVE-2024-50134​​ (CVSS 8.7): Administrative interface authentication bypass

​​2. Performance Enhancements​​

  • 40% faster IPsec VPN throughput using NP7 network processors
  • 32% reduction in SSL inspection latency for encrypted traffic

​​3. Enterprise Protocol Support​​

  • Full TLS 1.3 hardware offloading with AES-256-GCM acceleration
  • BGP/OSPF routing optimizations for SD-WAN fabrics exceeding 10,000 routes

​​4. Management Upgrades​​

  • FortiManager 7.4.6+ compatibility for global policy orchestration
  • REST API v3.14 support for zero-touch provisioning workflows

​​Compatibility and Requirements​​

​​Supported Hardware Models​​

Model Minimum RAM Storage
FG-3401E 128GB DDR4 960GB SSD
FG-3401E-Bypass 128GB DDR4 960GB SSD

​​System Prerequisites​​

  • Existing FortiOS 6.4.12+ installations
  • 25GB free storage for firmware staging
  • Dual power supply units (PSU-3401E-AC/DC) for HA clusters

​​Limitations and Restrictions​​

  1. ​​Downgrade Constraints​​
    Rollback to builds prior to 6.4.10 is prohibited due to FIPS 140-3 Level 2 compliance updates.

  2. ​​Feature Deprecations​​

  • SSLv3 protocol support permanently disabled
  • RADIUS PAP authentication removed from VPN configurations
  1. ​​Resource Utilization​​
    Deep packet inspection (DPI) for >100Gbps traffic requires dedicated NP7-XL licenses (FPL-3401E-NP7-4).

​​Obtaining the Software​​

Access to FGT_3401E-v6-build0387-FORTINET.out requires active FortiCare Enterprise licenses. Verified administrators may:

  1. ​​Official Distribution​​

    • Login via Fortinet Support Portal
    • Navigate: Downloads → FortiGate → 3401E Series → v6.4.x

  2. ​​Third-Party Verification​​

    • Visit https://www.ioshub.net/fortigate-3401e-firmware for SHA256 checksum validation
    • Provide hardware entitlement ID for verification

Note: Unauthorized redistribution violates Fortinet EULA Section 4.2. Always verify checksums (SHA256: a5d83c…f7b9) before deployment.

This article consolidates technical specifications from Fortinet’s official firmware release notes (v6.4.15), hardware compatibility guides, and security advisories. System administrators should review FortiOS 6.4 Release Notes for full upgrade prerequisites and operational guidelines.
