Fortinet FG-90G – Next-Generation Firewall

Fortinet FortiGate 90G FG-90G Next-Generation Firewall

Fortinet FortiGate 90G (FG-90G) is a high-performance next-generation firewall designed for distributed enterprise sites, branch offices and security-driven WAN deployments. It combines firewalling, secure SD-WAN, VPN, intrusion prevention, application control and other FortiOS-based networking and security capabilities in a compact desktop platform.

The FG-90G provides 8x GE RJ45 ports together with 2x shared 10GE RJ45/SFP+ media ports. Each shared port can be configured for compatible 10/5/2.5/1GE RJ45 or 10GE/GE SFP+/SFP connectivity, allowing organizations to select the appropriate copper or fiber interface for their network design.

Technical Specifications

Enterprise Network Security

The FortiGate 90G consolidates firewall protection and networking functions in a single FortiOS-based platform. It supports firewall policy enforcement, intrusion prevention, application control, secure connectivity, VPN and secure SD-WAN capabilities for distributed enterprise environments.

Fortinet positions the 90G as part of its Security Fabric architecture, allowing the appliance to work with compatible Fortinet security and networking products. FortiGuard AI-powered security services can provide additional threat intelligence and protection capabilities according to the selected subscription package.

Flexible 10G Connectivity

The FG-90G provides 8x GE RJ45 interfaces for conventional Gigabit Ethernet connectivity and 2x shared media ports supporting 10GE/GE SFP+/SFP or 10/5/2.5/1GE RJ45 connectivity.

This shared-port architecture allows network administrators to select copper or fiber connectivity according to deployment requirements. It is particularly useful for branch and distributed enterprise environments where a compact firewall may need high-speed 10GbE uplinks without requiring a larger rackmount appliance.

SP5 Hardware Acceleration

The FortiGate 90G is built around Fortinet's SP5 security processing architecture. Hardware acceleration helps improve the efficiency of supported networking and security functions while maintaining a compact desktop form factor.

Fortinet's September 2026 product matrix rates the FG-90G for up to 28 Gbps firewall throughput, 4.5 Gbps IPS throughput, 2.5 Gbps NGFW throughput and 2.2 Gbps threat protection throughput. These are published maximum performance figures measured under specified test conditions; actual performance varies with traffic characteristics, packet size and enabled security features.

Secure SD-WAN and VPN

The FG-90G integrates secure SD-WAN capabilities with its next-generation firewall functions. This enables organizations to apply security policies while managing multiple WAN connections and optimizing application traffic across distributed sites.

With published IPsec VPN throughput of up to 25 Gbps, the appliance can support high-capacity site-to-site VPN connectivity. Fortinet rates the platform for up to 200 gateway-to-gateway IPsec tunnels and up to 2,500 client-to-gateway IPsec tunnels.

Compact Deployment for Distributed Networks

The desktop form factor makes the FortiGate 90G suitable for environments where a compact security appliance is preferred over a 1RU rackmount firewall. It can be deployed at branch offices, retail locations, distributed enterprise sites and other network edges requiring 10GbE connectivity.

The appliance measures approximately 42 x 216 x 178 mm and weighs approximately 1.12 kg. It uses an external DC power adapter and can support a second external adapter for optional power redundancy.

FortiGate 90G vs FortiGate 91G

The standard FG-90G provides the same primary interface configuration as the FG-91G. The key hardware distinction is onboard storage: the FG-91G includes a 120GB SSD, while the standard FG-90G does not include that internal storage configuration. Confirm the exact SKU when storage is required.

Compatibility and Configuration Considerations

Before purchasing, verify the exact FG-90G hardware SKU, FortiOS requirements, FortiGuard services, FortiCare support and transceiver requirements. The shared media interfaces must be configured with compatible copper or optical connectivity according to the required network speed and media type.

When using 10GE SFP+ connectivity, select compatible Fortinet-supported SFP+ transceivers or direct-attach cables. For copper connectivity through the shared media ports, verify the supported Ethernet speed and transceiver requirements before deployment.
