MANAGING NETWORK TRAFFIC WITH SENSITIVE DATA

Technology related to managing network traffic with sensitive data is disclosed. In one example, a method can include performing a cryptographic transformation of sensitive data of a request from a requestor for a resource. A portion of the cryptographic transformation of the sensitive data of the request can be transmitted to a sensitive data server. One or more possible matches to the cryptographic transformation of the sensitive data of the request can be received from the sensitive data server. A match to the cryptographic transformation can be identified within the one of the one or more possible matches. In response to identifying the match, an access policy for the requestor or the resource can be changed.
