Is there a way to tune host DLP rules so that it would not count duplicate regex matches in to the threshold? We have a rule in DLP that matches credit card numbers using custom regex. I have given a threshold for this rule and when DLP is scanning emails and documents, it is counting duplicate credit card numbers to the threshold and hence even if a single credit card number is identified in a document which is more than the threshold, it generating an incident. Any idea how can I tune the rules to count unique matches instead of duplicate matches?
Thanks & Regards,
