Overview
FortiGate is Fortinet’s next-generation firewall (NGFW) line, running the FortiOS operating system. It combines firewalling, intrusion prevention, VPN, web filtering and SD-WAN, and many models use custom security processors (ASICs) to accelerate inspection. FortiGate is a central part of Fortinet’s broader Security Fabric.

Text description of this diagram
FortiGate inspects traffic between the internet and the internal network, using FortiGuard services for threat intelligence.
Key features
- Firewall, intrusion prevention (IPS), VPN and application control in one platform.
- Integrated SD-WAN for secure, optimised branch connectivity.
- FortiGuard subscription services for threat intelligence and content inspection.
- Custom security processors (ASICs) on many models to accelerate inspection.
- Security Fabric integration across Fortinet products.
Strengths
- Strong performance-per-cost, helped by purpose-built hardware acceleration.
- A broad, consolidated feature set covering firewall, VPN and SD-WAN.
- Wide range of models from small branch to large data-centre appliances.
- Tight integration with the wider Fortinet Security Fabric.
Limitations to weigh
- Managing many devices and policies can get complex at large scale.
- Full capability depends on active FortiGuard subscription services.
- The feature-rich interface has a learning curve for newcomers.
Deployment options
FortiGate is available as physical appliances across many sizes, as virtual machines for private clouds, and as virtual instances in public clouds — so the same operating system and policy model can span the whole estate.
Integrations
- The Fortinet Security Fabric (FortiManager, FortiAnalyzer, FortiSwitch, FortiAP and more).
- Third-party SIEM and automation through APIs and logging.
- Cloud platforms for hybrid and multi-cloud deployments.
Licensing
FortiGate combines the appliance or virtual-machine cost with FortiGuard subscription services for threat intelligence and content inspection. Confirm current model options, service bundles and pricing with the vendor or a partner.
Ideal use cases
- Branch and campus edge security with integrated SD-WAN.
- Organisations wanting a consolidated NGFW rather than separate point products.
- Environments that value hardware-accelerated inspection performance.
