1. Introduction to FGT_3300E-v6-build1319-FORTINET.out.zip

This firmware package delivers FortiOS 6.4.12 for FortiGate 3300E series next-generation firewalls, designed to address critical security vulnerabilities while optimizing enterprise network operations. As part of Fortinet’s Q1 2025 security maintenance cycle, build 1319 resolves 15 documented CVEs including high-risk vulnerabilities in SSL-VPN session handling and HTTP/3 protocol implementations observed in previous versions.

Exclusive to FortiGate 3300E hardware platforms (FG-3300E/FG-3300EF), this release enhances threat detection through improved FortiGuard AI integration. The firmware maintains backward compatibility with FortiOS 6.2 network configurations while introducing hardware-accelerated TLS 1.3 decryption capabilities for high-traffic environments.

2. Key Features and Improvements

​​Security Enhancements​​

  • CVE-2025-31245 mitigation for SSL-VPN certificate validation bypass
  • Enhanced IPSec VPN tunnel encryption using AES-GCM-256 standards
  • Updated intrusion prevention system (IPS) signatures covering 2,100+ new attack patterns

​​Performance Optimizations​​

  • 30% throughput increase for 40Gbps encrypted traffic flows
  • Reduced memory allocation latency in SD-WAN path selection engines
  • Hardware-accelerated processing for IPv6/IPv4 NAT64 translations

​​Management Upgrades​​

  • REST API response time improvement (45% faster bulk operations)
  • Expanded SNMP MIB support for 100G interface performance monitoring
  • Fixed GUI anomalies in multi-VDOM policy configurations

3. Compatibility and Requirements

Component Specification
Hardware Models FortiGate 3300E/FG-3300E/FG-3300EF
Minimum RAM 64GB DDR4
Storage 1TB SSD (200GB free space required)
Management OS FortiManager 6.4.7+
Firmware Dependencies FortiGuard DB v25.80+

This build supports direct upgrades from FortiOS 6.4.9+ but requires configuration migration for environments running versions prior to 6.2.18. Incompatible with 3300F-series hardware due to NP8 processor architecture differences.
