Introduction to FGT_3301E-v6-build1263-FORTINET.out Software

This firmware package delivers critical security enhancements and operational optimizations for Fortinet’s FortiGate 3301E Next-Generation Firewall. Released on April 2025 as part of FortiOS 6.2.10 maintenance updates, it addresses vulnerabilities in SSL/TLS inspection engines while improving threat detection capabilities for enterprise edge networks.

The firmware supports FortiGate 3301E devices with hardware revision 09-3301E-xxxx, requiring 8GB RAM minimum for full functionality. It maintains backward compatibility with FortiOS 6.0.x configurations but mandates clean installation when upgrading from versions below 6.0.4.
