Yearly Subscriptions


Energize Updates- This subscription will give you spam definition updates, anti-virus updates, firmware updates, and access to Barracuda's technical support during office hours. This is a required purchase with any Barracuda appliance for the first year. After the first year, you have the option of whether to renew or not. If you choose not to, you will probably see a significant decrease in performance with your appliance.


Instant Replacement- This is an optional subscription that will extend the hardware warranty appliance and provide for 24x7 technical support with Barracuda. The Instant Replacement service guarantees overnight replacement of your appliance in the event of failure.


Premium Support- This option is available on the Barracuda 600 and above. It will give you the fastest response time, a dedicated support team, and advanced notification of new repairs and features in upcoming software releases. In order to get premium support, both Energize Updates and Instant Replacement must be purchased as well.
