• Enables access to corporate intranets, file systems or other Web-based applications
• Tracks resource access through auditing and reporting facilities
• Scans uploaded files for viruses and malware
• Leverages multi-factor, layered authentication mechanisms, including RSA SecurID and VASCO tokens
• Integrates with existing Active Directory and LDAP directories
• Utilizes policies for granular access control framework
• Supports any Web browser on PC or Mac

Easy to Use:

With no client software to install and minimal configuration of the firewall, installation of the Barracuda SSL VPN Vx is quick and easy. It is designed to fit in a variety of network environments and is supported on most popular virtual hypervisors like VMware ESX and VMware ESXi. The entire virtual appliance, including hardware configuration, operating system and application modules are encapsulated for easy deployment. Once the virtual appliance is installed, configuration and administration is through the same intuitive Web based user interface as that on the hardware appliance.

With Barracuda Energize Updates, the Barracuda SSL VPN is continuously updated with the latest virus and application definitions every hour keeping maintenance at a minimum and eliminating administrative overhead. Updates are provided by Barracuda Central, an advanced 24x7 security operations center that works to continuously monitor and block the latest Internet threats.

Affordable:

With no per user fees, the Barracuda SSL VPN Vx provides the same flexibility and affordability as the Barracuda SSL VPN hardware appliance.

Compare Editions:

The Barracuda SSL VPN Vx is available in 4 editions capable of handling from 15 to 500 concurrent users. Multiple virtual appliances can be clustered for greater capacity and high availability. Also, the capacity and performance of the 600Vx can be easily expanded by licensing it to run on additional CPU cores on the virtual host cluster.

Deployments:

The screen-shots below illustrate deploying the Barracuda Virtual Appliance on a VMware ESX/ESXi hypervisor. Other deployment options are available. Please refer to the Setup Guide or contact Barracuda Networks.

	Connect to the VMware ESX/ESXi server from the vSphere client		Chose "Deploy OVF Template" and copy and paste the supplied URL.
	Ensure the OVF details are accurate and click "Next"		Read the End User License Agreement and indicate Acceptance
	Specify a name for the OVF instance and click on "Next"		Map the appropriate network in your virtualization inventory and click on Next
	The installation process for the Virtual Appliance will begin. This will take a few minutes.		Screenshot 8: Once installed, Barracuda Networks Virtual Appliances appear in virtualization environments just like any other virtual server. Administrators can configure network settings through the virtualization environment's console interface and then complete setup and configuration through a familiar Web interface.

A virtual appliance is a software image designed to run inside a virtual machine. When deployed inside a virtualization platform, such as VMware, multiple virtual appliances can share the physical resources of a single host computer while remaining logically isolated from each other. Barracuda Networks currently offers virtual appliance versions of many of its popular hardware appliance solutions to leverage the benefits of virtualization.

Barracuda Virtual Appliances provide the same technology found in the Barracuda Networks hardware solutions and are ideal for enterprises that are standardizing hardware platforms or with existing virtual environments. Barracuda Virtual Appliances can be deployed on standard virtualization platforms and can co-exist with other virtual machines, thereby enabling optimal usage of hardware resources. As the organization grows, virtual appliances can be scaled for capacity without changing any hardware or software configurations. Also, virtual appliances can be easier to backup and restore using standard mechanisms for disaster recovery.

Currently, Barracuda Virtual Appliances are supported on VMware ESX/ESXi 3.5 Update 2 and higher with a minimum of 512 Mb RAM (1 Gb recommended) and 40 Gb available hard disk space. For information regarding other hypervisors or virtual infrastructures (like VMware Server, CITRIX XenApp, Microsoft Hyper-V), please contact us.

Yes. Barracuda Virtual Appliances are specifically designed for ease of deployment in new or existing virtualization environments. The virtual appliances are fully encapsulated with the virtual hardware configuration and the setup process is simple. Once the virtual appliance is installed, configuration and administration is through the same intuitive Web based user interface as that on the appliance. Instructions can be found in the online setup guides available as part of the download or under the Documentation section atwww.barracuda.com/virtualization.

Yes. The Barracuda Networks Energize Updates subscription provides the latest security updates and is an essential part of purchasing either a Barracuda Networks hardware solution or a virtual appliance.

Once deployed, Barracuda Virtual Appliances are administered through the same simple Web based user interface found on the hardware equivalents. This makes it very easy for administrators of Barracuda Networks hardware appliances to support Barracuda Virtual Appliances without learning a new usage model.

Every active instance of a Barracuda Virtual Appliance must be supplied a unique license token that is obtained during the process of requesting an evaluation. If you choose the ZIP deployment method, the same ZIP file can be used for multiple deployments, but each deployment must be provisioned with a unique token. Cold backups, snapshots, host migration and other backup or disaster recovery operations are fully supported.

Yes. The “Linked Management” feature can be used to cluster a combination of Barracuda Virtual Appliances and hardware equivalents as appropriate.

Open Virtualization Format (OVF) is a standard to package and distribute virtual machines. It is a portable, platform independent file format that is supported by several hypervisors. An OVF file encapsulates the complete specification of a virtual machine including all the virtual disks, virtual hardware configuration (CPU, memory, networking) and storage. Barracuda Virtual Appliances are distributed as OVF templates that facilitate quick provisioning with little or no manual intervention.

New firmware releases will be available periodically and are included in the Energize Updates subscription. Once the virtual appliance is deployed, administrators can check for available firmware releases and upgrade as appropriate.

Barracuda Virtual Appliances do not involve any per user or setup fees. A Barracuda virtual appliance is licensed for a certain number of cores. As the organization grows, administrators can easily expand the capacity of these virtual appliances by licensing them for additional cores as needed without the overhead of provisioning any additional hardware or software.

A 30-day evaluation copy of any Barracuda Virtual Appliance can be obtained by filling the evaluation request form online at www.barracuda.com/virtualization. This will generate an email with download and activation instructions.
