How to Download and Install the Barracuda Content Shield Suite for Windows

  • Last updated on
The Barracuda Content Shield Suite for Windows supports Windows 10 (64 bit) and Remote Desktop Services 2012 R2 and 2016. For endpoint computers using Firefox, Barracuda Content Shield Suite requires Firefox 68.0 or later.

The suite is installed either manually or by RMM or GPO to endpoint machines. For information about deploying the suite via RMM tools, see How to Deploy the Barracuda Content Shield Suite Using RMM Solutions. The suite includes the following components:

  • Malware Prevention Component (MPC) – Local file risk analysis, checking against known malware signatures to provide an additional layer of Malware Prevention. Note that this component is disabled if you set Malware Prevention to Disabled on the THREAT POLICY page.
  • Web Filtering Component (WFC) – Content protection for web traffic.

After installing the suite, see How to Use the Barracuda Content Shield Suite for Windows for details about the user interface on the endpoint.

Windows Installation

For manual installation on one of the endpoint machines:

  1. Log into your Barracuda Content Shield account.
  2. Go to the Downloads page.
  3. Click Download to download the Windows Agent installer. The installer file is named BarracudaContentShieldSetup-[version].exe.
  4. Click Account Configuration File to download the configuration file. This file is named bcs.key. The configuration file is picked up by the installer when you run it. Put this file and the installer file in the same folder on the endpoint computer.

  5. Run the BarracudaContentShieldSetup-[version].exe  executable on the endpoint, accept the license agreement, and follow the prompts in the wizard to install.
  6. After browsing for the bcs.key file on the Locate Account Configuration screen, the wizard presents a Setup Type dialog with options for Complete or Custom installations:
    • Select Complete to install both the Web Filtering and Malware Prevention components,   – OR –
    • Select Custom to install either one of the components if you don't want to install both


When you uninstall the suite from the endpoint machine, you will be prompted to either reboot the machine or choose to reboot later. Barracuda recommends rebooting if you want to reinstall the suite at a later time.

Upgrade Using Windows

When you run the Windows installer, if there is a newer version of the Barracuda Content Shield Suite, you will see the Upgrade button in the installer Welcome screen. Click Upgrade and follow the wizard prompts. This will upgrade already installed components.

Automated Installation

You can either use an RMM or GPO to install and distribute to endpoint machines if you don't want to do manual installations. If you use an RMM or GPO, make sure to indicate that the installer (BarracudaContentShieldSetup-[version].exe) and the configuration file (bcs.key) must be in the same folder. See How to Deploy the Barracuda Content Shield Suite Using RMM Solutions for instructions using an RMM tool.

Command Line Installation (silent)

On one of the endpoint machines:

  1. Follow steps 1-4 above.
  2. From the command line, run the appropriate command from the examples in the table below, depending on your scenario.
    Note: For KEYPATH = "path/to/bcs.key" in the examples below, replace the example in italics with the path to the bcs.key file.
