Once you've configured Skyhigh Security Cloud to synchronize classifications from Trellix DLP, you can create policies using those classifications .
Go to Policy → DLP Policies and select Create a new DLP Policy from the Action menu.
For Type, choose API.
For Content, choose Trellix On Prem DLP.
Important
When you choose Trellix On Prem DLP for Content Rule, the rules you use in policies can only be classification rules or collaboration rules.
If you are looking for content matches only (for example, looking for documents with 10 or more social security numbers), then use the classifications rules. If you are looking for content matches, combined with a cloud context (for example, looking for documents with 10 or more social security numbers that are being shared with external users), then use the classifications rules, combined with collaboration rules
For Services, select one or more of the cloud services you selected to use On Prem DLP Classifications.
Define the rest of the policy, including any response actions, and click Save.
