1. A computing device to provide access blocking as part of data loss prevention (DLP) within a collaborative service environment, the computing device comprising: a memory configured to store instructions; and a processor coupled to the memory, wherein the processor is configured to: detect an action associated with content processed by a collaborative service; determine if the action matches access blocking criteria defined by one or more DLP policy rules; in response to a determination that the action matches at least one access blocking criterion defined by the one or more DLP policy rules, activate a block access tag associated with the content, ignore previously defined permissions associated with the content, and restrict access to the content to users; and in response to a determination that the action does not match at least one of the access blocking criterion, provide a notification to the users through a user experience of the collaborative service, wherein the notification includes a link to a DLP policy document that includes the one or more DLP policy rules, a link to a location of the content, and control elements associated with one or more actions; and enable one or more of the users to execute one or more of the control elements to deactivate the block access tag, reinstate the previously defined permissions associated with the content, and revoke the restricted access to the content.
