Abstract: This disclosure describes techniques for data path monitoring and visibility in communications among network devices. The techniques include determining that personally identifiable information (PII) is included in a data traffic flow intended for delivery to a destination endpoint. A probe may be sent from a source endpoint to identify an intended data path of the data traffic flow to the destination endpoint. The techniques include validating the intended data path of the data traffic flow against a policy related to data routing. Based at least in part on a result of the validation, the techniques may include allowing or dropping the data traffic flow, or various other actions.
