How to Install the Barracuda WSA with the Barracuda Web Security Service

  • Last updated on

Barracuda Networks recommends reading this entire article and associated release notes (see links below) before installing the Barracuda Web Security Agent (WSA). After the Barracuda WSA is installed and configured, your web traffic is protected by the Barracuda Web Security Service automatically. See also:

To route all web traffic from Windows or Mac laptops or desktops through the Barracuda Web Security Service:

Step 1. Create an Authentication Key using the Barracuda Web Security Service that you will enter during the Barracuda WSA installation process.

The Authentication Key enables the Barracuda Web Security Service to identify traffic from your remote computer(s).

  1. In the Barracuda Web Security Service Manager, go to CONFIGURATION > Key Management, and click Add New Key.
  2. Type a Name for the authentication entry.
  3. Select the Barracuda Web Security Service Connector/Web Security Agent option; copy the value in the Key field and save it to a secure place. You will enter the Authentication key during Agent installation. Click Save Changes.

Step 2.  Download either the MSI or EXE installer for the Barracuda WSA for Windows, or the DMG file for Mac from the SUPPORT tab of the Barracuda Web Service Manager. See Windows Installer (MSI) and Windows InstallShield (EXE) documentation for information about Windows command line options.

  • Using the Windows EXE – Installer EXE files can contain any kind of executable code to run, such as a batch file. The Barracuda WSA EXE (bootstrapper) installer runs a check for requirements before installation. You can use the Barracuda WSA EXE installer inside a batch file to install on a Windows PC from the command line, or to install automatically using a GPO.

  • Using the Windows MSI Installer – MSI files are database files, used by Windows Installer and contain information about an application. MSI files are executed by an EXE file that is part of Windows, called msiexec.exe. The Barracuda WSA .msi file does NOT run a check for requirements before installation.

    You must have Microsoft .NET framework installed before you install the Barracuda WSA using the MSI installation method. The MSI file does not install the.NET framework for you. If you do not install the .NET framework before you begin installation with the .MSI file, a message appears prompting you to download and install the .NET framework and then install the Barracuda WSA. For Microsoft .NET Framework and Windows version compatibility, see Requirements for the Barracuda Web Security Agent With Windows.

    To download the installer file:

  1. Log into the Barracuda Web Security Service Manager interface.
  2. Click Barracuda Web Security Service at the top of the Barracuda Cloud Control account screen. The Barracuda Web Security Service Manager interface appears on the screen.
  3. From the SUPPORT tab of the Barracuda Web Service Manager, select the Barracuda Web Security Agent version you want to download to your system. Also note the Service Host URL that appears on the SUPPORT tab, as you will enter this into the Barracuda WSA client so it knows where to direct web traffic. Either the .exe or.msi installer  can be used to install through GPO or manual installation.

Step 3. Install the Barracuda WSA for Windows either from the command line, using the automated installation option with an MSI or EXE file, or using Windows GPO.
