DLP content filtering for credit card numbers
We have improved the Remove Sensitive Content action to properly recognize credit card numbers. This option now utilizes the modulus 10 (aka Luhn) algorithm, which validates credit card numbers. As an Exchange administrator, you can set up the program to remove any credit card number from users’ correspondence to protect company data from leakage.
