Provilla secures the enterprise's data by fingerprinting it and deploying control agents on the desktops. Its LeakProof solution traces files from within the Windows Kernel and monitors all file-handling operations (open, read, copy, dump, attach to a mail, etc...).

LeakProof uses desktops clients and an appliance server to centrally manage what files are deemed sensitive, and to track their use. Provilla developed what it calls "DataDNA", which is essentially a fingerprinting method allowing to track files over the company's network and mobile assets. Provilla claims this fingerprint stays the same even if the file is altered and saved as a new document.

The details of this acquisition is unknown. Trend Micro announced Provilla will keep operating as a subsidiary, with its products still sold as stand-alone solutions for the near term. The technology, of course, will progressively be integrated in Trend's own product line.
