Web Portal

A web portal provides remote users with easy access to their assigned resources. Navigation is so easy that users in the office often prefer use the portal to access their network resources as well.

Multiple User Realms

Administrators use realms when an organization has multiple user databases. Realms let the Barracuda SSL VPN Vx authenticate against multiple domain servers and directories such as LDAP and NIS.

SSL Tunnelling

The Barracuda SSL VPN Vx securely connects remote users through SSL-encrypted tunnels from any web browser. No client software is necessary. However, for richer tunnelling, the Barracuda SSL VPN Vx offers the Barracuda SSL VPN agent, a lightweight Java tunnelling client. This agent supports remote applications such as Remote Desktop Services, Citrix XenApp, VNC, NX, SSH, and Telnet.

Antivirus

The Barracuda SSL VPN Vx automatically scans files uploaded to the network file system and from intranet web applications for viruses, spyware, and other malware. Barracuda Energize Updates keep virus definitions current in real time to prevent even the latest malware from uploading to the network.

Virtual Keyboard

The virtual on-screen keyboard is a security feature that defends against key-logging attacks. The virtual keyboard echoes characters the user clicks on.

Automatic Cache Cleaning

A cache-cleaning utility automatically clears session data from the user's web cache and history when the user logs out or disconnects. Cache cleaning prevents unauthorized exposure of information when users access the Barracuda SSL VPN from public or shared computers.

Site-to-Site Connectivity

The Barracuda SSL VPN Server Agent streamlines connections to services at remote sites without the risks and burden of using a fully routed IPsec connection. The Barracuda SSL VPN Server Agent directly connects to services hosted on remote sites from the Barracuda SSL VPN Vx.
