Frequently Asked Questions

Does the Barracuda Web Security Gateway support off-network users?

Yes. The Barracuda Web Security Agent comes with the Barracuda Web Security Gateway 410 and higher models. The Barracuda Web Security Agent is downloadable client software for installation on off-network Windows and Mac computers. The agent provides the same malware protection and policy enforcement as configured on the Barracuda Web Security Gateway appliance. Administrators can configure the agent to either route traffic through a central Barracuda Web Security Gateway or route traffic through a local gateway to lookup policies and enforce rules locally.

Can the Barracuda Web Security Gateway block different sites for different users?

Yes, the Barracuda Web Security Gateway lets administrators customize policies for specific users, groups, and IP address ranges in the organization. Administrators can also establish time ranges for those policies.

Custom policy examples:

  • To prevent users from job hunting while at work, create a policy that gives only the human resources group access to job-board sites.
  • Defining separate access policies for teachers and students.
  • Grant unrestricted web access to compliance officers for investigations.
  • The Barracuda Web Security Gateway integrates with LDAP directory servers for user and group membership information. It also integrates with Windows domain controllers for easy user authentication.

What kinds of directory servers are supported?

The Barracuda Web Security Gateway supports any LDAP compatible directory server, including Active Directory, Domino Directory, eDirectory and Open LDAP.

How are users authenticated?

The Barracuda Web Security Gateway supports three types of authentication:

  • For Windows domains, the Barracuda Web Security Gateway has Barracuda DC Agent software to install on Windows Domain Controllers. This software monitors Windows login events and maps Windows user names and IP addresses to the Barracuda Web Security Gateway to transparently apply user policy.
  • When users try to access a blocked resource, the Barracuda Web Security Gateway displays a page that requests a username and password. This method doesn't require the Barracuda DC Agent or configuring users' browsers.
  • If configured in forward proxy mode, the Barracuda Web Security Gateway can use standard proxy authentication in which browsers send the authentication credentials in the HTTP headers. This form of authentication can require a one-time configuration of users' web browsers. Proxy authentication is not compatible with the Barracuda Web Security Gateway while running in transparent mode.

If I have a proxy server in my network, how would I deploy the Barracuda Web Security Gateway?

The Barracuda Web Security Gateway can work with your proxy server either as a cascading proxy server or in transparent mode. We normally recommend replacing a proxy server with the Barracuda Web Security Gateway.

Can the Barracuda Web Security Gateway operate in VLAN environments?

Yes. The Barracuda Web Security Gateway is fully compatible with VLAN environments.
