DLP rules configured for non-file detection are required to prevent exfiltration of sensitive data to ChatGPT. You can further modify the DLP rule to enforce your organization’s data security standards. The DLP rule has an identical name as the data profile from which it was automatically created.
You can keep
File Based Matched Criteria
enabled or disable as needed. Enabling this setting has no impact on detection of egress traffic to ChatGPT as long as
Non-File Based Match Criteria
is enabled.

Navigate to the Action and Advanced Inspection section, and select the
Profile Group
you created in the previous step.

Configure the Security policy as needed.
The
Action
you specify in the data profile determines whether egress traffic to ChatGPT is blocked. The Security policy rule
Action
does not impact whether matched traffic is blocked.
For example, you configured the data filtering profile to
Block
matching egress traffic but configure the Security policy rule
Action
to
Allow
