Currently, there is no synchronization between Cloud Discovery and the On-Premises version of Lansweeper.
Cloud Discovery scans are stored exclusively in your cloud-based inventory, where they can be leveraged for integrations, used via the Data API, and enriched with features such as Risk Insights.
