Introduction to FGT_1100E-v6-build1190-FORTINET.out.zip

This firmware package delivers mission-critical security enhancements and operational optimizations for ​​FortiGate 1100E​​ next-generation firewalls operating under FortiOS 6.x architecture. Designed for large-scale enterprise networks requiring hyperscale threat prevention, build 1190 resolves 12 CVEs identified in Q1 2025 while improving SSL/TLS inspection throughput by 33%. Exclusively compatible with FortiGate 1100E hardware variants, this release enhances Security Fabric integration and refines SD-WAN application prioritization logic for hybrid cloud environments.

Built on FortiOS 6.4.12 core infrastructure, the update became available through Fortinet’s support portal on May 8, 2025. It requires configurations with ≥48 GB RAM and utilizes NP8 security processors for hardware-accelerated decryption capabilities.
