The Enforced Allowlists feature allows you to send properties classified as PHI to your HIPAA-compliant destinations, and send only non-PHI properties to non-HIPAA compliant destinations. Freshpaint does this by allowing you to specify a list of properties that are known to not contain PHI. Whenever Freshpaint sees an event or user property that is not in this allowlist, Freshpaint will remove the property before sending the event or identify request to non-HIPAA compliant destinations.
