For more questions about your Barracuda SSL VPN license, contact your Barracuda Networks sales representative.

The Barracuda SSL VPN virtual and physical appliances both have different base licences. For both appliance types, add-on subscription licenses are also available.

Hardware licenses

Hardware appliances are limited only by the performance of the appliance's hardware. There is no limit to how many users can concurrently connect to the appliance. To help you size the appliance, Barracuda Network provides a recommended number of concurrent users. If you are using the appliance with more than the recommended number of users, its performance declines, but users can continue using it.

Vx licenses

Virtual licenses are limited by the number of CPU cores that are licensed for the appliance model. There is no per user license. If you use your Barracuda SSL VPN Vx with more users than recommended, the performance of the appliance declines but no users are blocked. When your user base grows, you can upgrade the license and add additional cores to the virtual machine for increased performance.

Subscription-based licenses

The following subscription-based licenses are available:

Energize updates

Energize Updates offer the latest firmware, application definition, and security updates for your system. It also includes standard technical support (24x5).

Instant replacement

With Instant Replacement, a replacement for your Barracuda SSL VPN hardware ships within 1 day if your appliance fails. Every 4 years, your Barracuda SSL VPN is replaced by a new appliance with the latest hardware for your SSL VPN model. Standard technical support (24x7) is also included.

An active Energize Updates subscription is required for the Instant Replacement subscription.

Premium support

Premium Support subscriptions offer the highest level of 24/7 technical support for mission critical environments. Barracuda Networks is committed to meeting the demands of these environments by providing a dedicated and highly-trained technical support team.

An active Energize Updates subscription is required for the Premium Support Subscription.
