Getting started

FortiOS is the operating system that runs on Fortinet’s FortiGate Next-Generation Firewall (NGFW). It supports different platforms, including:

• Physical appliances

• Hypervisors

• Cloud computing platforms

FortiOS delivers security as a hybrid mesh firewall that spans a meshed topology of on-prem and cloud environments. With FortiGuard's AI-powered security services, FortiOS provides protection across the attack surface with IPS, advanced malware protection, web security, inline malware prevention, data loss prevention, and more.

In addition, FortiOS is central to the SD-WAN solution by providing SD-WAN functionality and intelligence in a single FortiGate, a mesh of FortiGates, or integrated into a SASE environment. It is also central to the Zero Trust Network Access (ZTNA) solution by making policy decisions and applying policy enforcement based on security posture input.
