  • Security Agents update from the Security Server, Update Agents, or the Trend Micro ActiveUpdate server.

    Messaging Security Agents update only from the Security Server.

    For details on the update process, see Update Overview.

    Similarly, a pure IPv4 agent cannot obtain updates directly from a pure IPv6 Security Server/Update Agent.

    In these situations, a dual-stack proxy server that can convert IP addresses, such as DeleGate, is required to allow the agent to obtain updates.

  • For details on the components that agents update, see Updatable Components.

  • In addition to the components, agents also receive updated configuration files when updating from the Security Server. Agents need the configuration files to apply new settings. Each time you modify agent settings through the web console, the configuration files change.
