Verify the OS proxy settings in Server & Workload protection and for the agent.

In Server & Workload protection, the option to use the OS proxy is enabled by default and cannot be disabled. TrendAI™ recommends configuring proxy settings on the endpoint operating system to ensure your endpoints can still connect with TrendAI Vision One™ if other proxies are unavailable.

Proxy settings configured in Endpoint Inventory take priority over settings configured in Server & Workload protection.
Server & Workload Protection supports using the OS configured proxy for the following agent versions:
  • Linux: agent version 20.0.0-7303 and later
  • Windows: agent version 20.0.0-3530 and later
  • macOS: agent version 20.0.0-167 and later
Use the following steps to verify the OS proxy settings in your TrendAI Vision One™ console:
  1. In the TrendAI Vision One™ console, go to Endpoint Security → Server & Workload Protection → Administration → System Settings → Proxies.
  2. Under Proxy Server Use, check that Allow agents to apply OS proxy when configured proxy is inaccessible is set to Yes and the drop-down is disabled.
You can also ensure the setting is enabled on the endpoint.
  1. Open the console or command prompt with Administrator privilege and access the Deep Security Agent folder.
    1. For Windows, this is usually C:\Program Files\Trend Micro\Deep Security Agent.
    2. For macOS, this is usually /Library/Application Support/com.trendmicro.DSAgent.
  2. Run the command dsa_control --autoDetectOSProxy 1.
If any errors occur, check the following:
  • The option is enabled in Server & Workload Protection
  • Any policy has successfully deployed to the agent
  • The agent is activated
  • The proxy settings are properly configured in the OS settings
  • The automatic configuration script is set
    If set, verify the script works.
  • If the endpoint is not using the OS proxy, verify if you have configured proxy settings in TrendAI Vision One™
    The endpoint uses the following hierarchy:
    1. Configured in Endpoint Security → Endpoint Inventory → Global Settings → Proxy Settings
    2. Configured in Server & Workload Protection
    3. OS proxy
