What are FortiGate and FortiOS?

FortiGate is Fortinet's Next-Generation Firewall (NGFW). Unlike a classic firewall that only inspects IP addresses and ports, an NGFW also identifies the application, the user and the content inside the traffic.

Core components

• FortiOS — the device operating system; every feature (policy, VPN, IPS) lives inside it.
• NP/CP ASICs — dedicated hardware chips that accelerate packet forwarding and encryption.
• FortiGuard — a cloud service delivering antivirus, IPS signature and web-rating updates.
• Security Fabric — links FortiGate, FortiSwitch, FortiAP and FortiAnalyzer into one security picture.

Operation modes

• NAT/Route Mode — the default: FortiGate acts as a router with IPs on its interfaces.
• Transparent Mode — the device behaves like a bridge inside an existing network, without changing addressing.
