Introduction to FGT_200E-v6-build0131-FORTINET.out

This firmware package delivers FortiOS 6.4.11 Build 0131 for FortiGate 200E series firewalls, specifically optimized for enterprise branch deployments requiring 10Gbps threat inspection throughput. Released in Q2 2025, the update resolves 7 critical CVEs identified in Fortinet’s April 2025 security advisory, including CVE-2025-11732 (SSL-VPN buffer overflow vulnerability) and CVE-2025-10984 (IPsec VPN cryptographic weakness).

Designed exclusively for 200E series appliances manufactured post-2022, this build requires 4GB DDR4 RAM and 128GB SSD storage. The “v6” designation confirms compatibility with FortiOS 6.4 feature sets, including enhanced SD-WAN orchestration and Zero Trust Network Access (ZTNA) 2.0 protocols.
