  1. Check if the correct steps are performed to register Deep Discovery Inspector

    There are two ways to register Deep Discovery Inspector to TrendAI Vision One. One is to use Deep Discovery Director On-Premises and the other one is to use Network Inventory service in TrendAI Vision One. Trend Micro recommends using Network Inventory service to register Deep Discovery Inspector. For more details, check Enabling TrendAI Vision One integration in Deep Discovery Inspector

     
    In case you want to switch the registering way from using the Deep Discovery Director On-Premises to the Network Inventory service, follow steps 1 and 2 (step 3 is optional) described in Deep Discovery Inspector and Service Gateway integration via TrendAI Vision One.
