We were included in Gartner analyst Debra Logan’s new "Choosing an E-Discovery Solution in 2007 and 2008" report. She covers a wide range of needs and vendors with a pretty comprehensive view of the e-discovery landscape. It is available via the Gartner website.
Although MessageGate is not a pure e-discovery company and we do not provide evidence production and review capabilities, we are seeing the need for smarter ways to sort, classify, and control email under the banner of e-discovery. As companies begin to tally the cost of litigation, it is making more and more sense to prepare for this unfortunate business reality. Beyond litigation preparation, we have helped companies with forensic and investigative review of high volumes of email. Our approach is different than the standard ingest, index, review process of search-oriented solutions. Rather, we effectively "replay" the messages through our policy engine with rules set to detect certain directions, users/user groups, documents, phrases, times, etc.
