Trellix constantly enhances and updates its agent software. It is important that you keep the software versions on your agents current to ensure they have the most up-to-date protection. This section describes how to obtain agent software and how to maintain the agent versions available on your Endpoint Security (HX) server.
New agent installation software images are not automatically included with the Endpoint Security (HX) server. After your Endpoint Security (HX) server has been installed or upgraded and the server has connected with Trellix's Dynamic Threat Intelligence (DTI) cloud, the newest versions of the agent software images for each platform (Windows, macOS, and Linux) are automatically downloaded to the Endpoint Security server for you. This automatic download may take up to an hour to occur.
After it has connected to the DTI cloud, your Endpoint Security (HX) server checks for newer agent software every hour. If newer agent software is available, the Endpoint Security (HX) server obtains it, stores it, and makes it available for you to download to your agents.
Previously installed agent software images are retained after you upgrade the Endpoint Security (HX) server.
If you do not automatically link your Endpoint Security (HX) server to the DTI cloud or if you need an earlier version of the agent software, you must obtain the installation image manually from the DTI cloud or the offline portal and upload it to the Endpoint Security (HX) server. See Manually retrieving installation images from the DTI Cloud or Obtaining agent images using the offline portal for more information.
Important
Agent installation images obtained manually must be uploaded to the Endpoint Security (HX) server before they can be deployed to your host endpoints. This ensures that the correct agent configuration file and agent certificates are included in the agent installation package you deploy to your host endpoints.
If agent software has not yet been downloaded to your Endpoint Security (HX) server, the following message appears on the Agent Versions tab:
No agent installation software was found. Agent installation software is automatically downloaded from DTI or can be manually uploaded.
