How do we enable DLP detection for Slack?
Symantec Data Loss Prevention 15.x, 16.x, 25.x
Slack does not integrate directly with DLP. For Slack monitoring you'll need to integrate DLP with CASB (CloudSOC) using the Slack Gatelet/Securelet.
Note: CASB configuration will require proxy forwarding or the use of the WSS agent.
See CASB documentation for more information
