1. A method of protecting a document at a first computing machine, comprising:
instrumenting a calling application of the first computing machine with a document protection mechanism, the document protection mechanism having a document protection mechanism interface, wherein the calling application is a data leak protection (DLP) application and has a policy associated therewith, wherein instrumenting the calling application with the document protection mechanism interface transforms the calling application to provide a secure document exchange function between the first computing machine and a second computing machine located remote from the first computing machine; and
upon a given occurrence and using the document protection mechanism interface, invoking an encryption utility to encrypt the document prior to its transfer to and receipt at the second computing machine, the encryption utility located in a processing environment distinct from the first computing machine and configured to encrypt the document according to the policy.
