Registering and downloading your license
FortiGate-VM for Azure supports both bring your own license (BYOL) and pay as you go licensing models. If you are deploying a FortiGate-VM in the Azure marketplace with BYOL, you must obtain a license to activate it.
You can obtain licenses through any Fortinet partner. If you do not have a partner, contact azuresales@fortinet.com for assistance in purchasing a license.
