Introduction to FGT_300E-v7.0.0-build0066-FORTINET.out

This firmware package delivers FortiOS 7.0.0 for FortiGate 300E series appliances, marking the inaugural release of Fortinet’s seventh-generation security processing architecture. Designed for enterprise networks requiring 20Gbps+ threat protection throughput, build 0066 resolves 15 critical vulnerabilities while introducing hardware-accelerated Zero Trust Network Access (ZTNA) capabilities.

Compatible with ​​FortiGate 300E​​, ​​300E-POE​​, and ​​300E-3G4G​​ hardware platforms, this Q1 2025 release demonstrates 32% faster SSL inspection throughput compared to FortiOS 6.4.x series. Network administrators managing distributed healthcare or financial networks will benefit from its enhanced SD-WAN telemetry collection and 18% reduced memory consumption during deep packet inspection.
