Agent & Extension

How much memory and CPU does DefensX agent consume?

DefensX Agent is a super lightweight agent and does not consume >10MB memory or >%0,1 CPU

Will it slow down my computer?

Our agent does not decrypt traffic on the end-point, which is one of the main reasons for slow-down on computers, so you will not feel any slow-down because of our agent.

What is the query response time for a DNS policy lookup from the cloud?

Every DefensX agent is a relay agent, that’s why a cached DNS lookup is less than 1ms.

How can I change Incognito mode for specific users?

In case you would like to enable incognito mode, you will need to have a separate deployment group.

Policies → End Point Deployments → New Deployment

While deploying the agent, you will need to add specific parameters to your install script. 0 will enable the end-user to use incognito mode, 1 will disable the incognito mode. System Default is 1.

  • EDGE_DISABLE_PRIVATE_WINDOW=0

  • CHROME_DISABLE_PRIVATE_WINDOW=0

  • BRAVE_DISABLE_PRIVATE_WINDOW=0

  • VIVALDI_DISABLE_PRIVATE_WINDOW=0

  • CHROMIUM_DISABLE_PRIVATE_WINDOW=0

  • FIREFOX_DISABLE_PRIVATE_WINDOW=0

Tip
DefensX advanced protections are disabled in incognito mode, we recommend to enable incognito for administrators or expert users.

In example, following RMM script will deploy DefensX with incognito mode enabled, for only Chrome browser:

msiexec /i DefensXInstaller.msi KEY=<DEPLOYMENT_KEY> ENABLE_LOGON_USER=1 ENABLE_IAM_USER=0 CHROME_DISABLE_PRIVATE_WINDOW=0

Similarly following will enable incognito for Chrome and Edge:

msiexec /i DefensXInstaller.msi KEY=<DEPLOYMENT_KEY> ENABLE_LOGON_USER=1 ENABLE_IAM_USER=0 CHROME_DISABLE_PRIVATE_WINDOW=0 EDGE_DISABLE_PRIVATE_WINDOW=0
Important
For the changes to take effect, you may need to restart the web browser by exiting from all the open instances.

How can I exclude some browsers from the extension installation?

If you want to exclude some browsers from the DefensX extension, you can un-select the related option when installing it through the installer GUI.

To set this option using a RMM script, you need to append ADDLOCAL property [1] to the MSI installation command.

In this case, you need to provide all of the component names which you want to install. Possible component names are:

Component Name Description
