Keeping your Barracuda Web Security Gateway Energize Updates (spyware, virus and other definitions) subscription up to date is critical for providing the best protection for your network and user web traffic. The Barracuda Web Security Gateway will prompt you with a message at the top of the BASIC > Dashboard page before the subscriptions expire. If they do expire, the change in functionality of the system is described in the article When Your Energize Updates Subscription Expires.
Update Your Barracuda Web Security Gateway Firmware
Use the ADVANCED > Firmware Update page to manually update the firmware version of the system or revert to a previous version. If you have the latest firmware version already installed, Download Now is disabled.
Update the Definitions from Energize Updates
The ADVANCED > Energize Updates page allows you to manually update the Spyware, Virus, Application, Access Point, and Security Definitions used on your Barracuda Web Security Gateway, as well as to change the interval at which the Barracuda Web Security Gateway checks for updates.
Barracuda Networks recommends setting the Automatic Updates to On for each type of definitions update so that your Barracuda Web Security Gateway receives the latest rules as soon as they are available by Barracuda Central.
