FG-51G Overview
The FortiGate FortiWiFi 50G series integrates firewalling, SD-WAN, network controller, and security in one appliance, making them perfect for building secure networks at distributed enterprise sites and transforming WAN architecture at any scale.
The 50G series runs on FortiOS, a converged networking and security platform with secure AI controls and quantum-safe protection. This single OS approach enables businesses to gain benefits of operational efficiency and unified protection from the seamless integration of Fortinet solutions within a hybrid mesh firewall architecture.
As a cornerstone of the Fortinet Security Fabric platform, the FortiGate NGFW works seamlessly with FortiGuard AI-Powered Security Services to deliver coordinated, automated, end-to-end threat protection in real time.
The 50G family is built on the patented SD-WAN-based ASIC, which delivers unmatched performance over traditional CPUs with lower cost and reduced power consumption. This application-specific design and embedded multi-core processor further accelerate the convergence of networking and security functions in the 50G family to optimize secure connections and deliver a robust user experience at branch locations.
FortiGate 51G firewall is equipped with 5 GE RJ45 ports including 4 internal ports and 1 WAN port, and built-in 64GB SSD storage for local data storage needs.
