Enable aggressive mode on targeted endpoints to provide more sensitive detection and response.

Important
Important
  • Detection mode and aggressive mode are pre-release sub-features and are not part of the existing features of an official commercial or general release. Please review the Pre-release Sub-Feature Disclaimer before using the sub-features.
  • Enabling aggressive mode raises the sensitivity level of the anti-malware scan and behavior monitoring, which might affect system performance and increase the number of Workbench alerts.
  • Aggressive mode supports a maximum of 20 active endpoints.
  • Aggressive mode currently only supports agents deployed to 64-bit (x86-64) operating systems using the agent installer package downloaded from Endpoint Inventory.
  • Server & Workload Protection agents deployed using the packages downloaded from the Software screen are not supported.
The Detection Mode option in Endpoint Inventory allows you to configure endpoints to utilize normal scanning behavior or to enable aggressive mode. Aggressive mode allows for more strict monitoring and response for situations such as on-going threat investigations, penetration testing, or prioritizing monitoring of sensitive assets.
Aggressive mode currently only applies to endpoints managed by Server & Workload Protection and Standard Endpoint Protection Managers. You must configure the settings in the protection manager before enabling aggressive mode. Use the steps below to prepare your environment and enable aggressive mode.

Procedure

  1. Configure your Standard Endpoint Protection Manager.
    1. In the Trend Vision One console, go to Endpoint SecurityStandard Endpoint Protection.
      If you have more than one Standard Endpoint Protection instance provisioned, navigate to the instance you want to configure.
    2. Go to PoliciesPolicy Management and edit the policy assigned to the endpoints you wish to use to enable aggressive mode.
