Central scanning and Security Servers

Central scanning allows you to reduce the resources needed on your virtual machines by setting up hosts where you can store scan signatures on and perform scans from. To do this, you need to install Security Servers on all your hosts, and link them to virtual machines with the BEST agent installed.

A Security Server is a dedicated virtual machine that de-duplicates and centralizes most of the antimalware functionality of antimalware clients, acting as a scan server.


The feature is designed for virtual machines, but you can also use central scanning on computers. Keep in mind that using the feature on a computer will not count towards the same seat/subscription usage.

You must install BEST on the virtual machines where you want to use this feature using a installation packages with Custom scan modes, and setting the main scan mode to Central Scan. The agent then connects to Security Server over TCP/IP, using details configured at installation or via a policy.


Central Scanning is dependent on the following components:

  • GravityZone Control Center

  • Security agent (Bitdefender Endpoint Security Tools installed on virtual endpoints)

  • Security Server

Deploy the Security Servers and set up Central Scanning

Install the Security Servers

Before installing your Security Servers, please take into consideration the number of virtual machines you want protected using Central scanning. Based on that number, the resources available for the Security Server on the chosen hosts, as well as network connectivity between the Security Servers and the protected virtual machines, establish the number of Security Server instances you will require.

Minimum requirements

You can find the requirements for installing a Security Server here.

Installation methods

You can use one of these methods to install Security Servers:

Deploying the BEST agent with Central Scan

There are three possible scenarios for deploying Central Scan on your endpoints:

Test out Central Scanning

Check deployment and configuration

To make sure all components have been deployed and configured correctly, use one of these methods:

Run a scan on the endpoints you previously deployed central scan and check the results of the task
  1. Log in to GravityZone Control Center.

  2. Go to the Network page from the left side menu.

  3. Select the endpoints where central scanning is applied.

  4. Click the task.pngTasks button at the upper side of the table.

  5. Select Malware scan.

  6. Select the type of scan you want to use.


    For more information refer to Scanning for malware for Windows and Scanning for malware for Linux.

  7. Click Save to confirm the request.


    For more information, refer to ???

  8. Go to the Tasks page from the left side menu.

  9. Click on the one of the endpoints you ran the scan on to view the results.

If the task is successful and scan was performed we can confirm that the deployment and configuration was successful:

View an endpoint's details
  1. Log in to GravityZone Control Center.

  2. Go to the Network page from the left side menu.

  3. Click the name of the endpoint you want to check.

  4. Go to the Protection tab and check the Primary scan engine field and the Associated Security Servers section:


Check Security Server allocation

Test out the Antimalware feature on endpoints with Central Scanning

  1. Log in to GravityZone Control Center.

  2. Go to the Policies page from the left side menu.

  3. Select one of the policies you are using and click Clone Policy.

  4. Click on the new policy to edit it, go to Antimalware > On-Access, and make sure On-access Scanning is disabled.

  5. Save the policy.

  6. Apply the policy to one of your endpoints where you want to test the feature.

  7. Create a test folder on your endpoint.

  8. In the test folder create a .txt file called and paste in the following line:

  9. Save the file.

  10. Create a scan task:

    1. Go to the Network page from the left side menu and select the endpoints you want to run the scan.

    2. Click the Tasks button in the upper side of the page.

    3. Select Malware scan.


      For more information, refer to Malware scan

    4. Under Type select Custom Scan.

    5. Go to the Target tab and add the path of the test folder you created earlier.

    6. Click Save.

The Antimalware On-Access protection feature will automatically detect the EICAR file and move it to quarantine.


Once done testing, re-apply the original policy to the endpoint you used for testing.

Create portlets for Antimalware data for the endpoints that use Central Scanning

Portlets provide you with security event information from your environment. You can customize the portlets and create your own, specifying the protection mechanism you would like the monitor and the time interval you would like to see in the data.

For information on how to create and manage portlets, refer to Dashboard and Executive Summary.


There is a portlet available for each report type provided by the console.
