To register your firewall, you can click Register in the web management interface, and then enter your MySonicWall credentials. If you don't have a MySonicWall account, refer to Creating a MySonicWall Account for instructions.
You can also log in to MySonicWall from a browser at https://mysonicwall.com and register your firewall there. When registration is complete, synchronize your licenses from within SonicOS.
Registration in MySonicWall requires your serial number and authentication code, which you can find on the appliance label or on the Device screen of the HOME | Dashboard > System page.
You can purchase additional Security Service licenses by clicking Licenses in the row for your firewall on the My Products page in MySonicWall.
After product registration, be sure to download the latest firmware and upgrade your firewall.
