#5. Consentry Networks
Milpitas, Calif.-based developer of network access control solutions.
ConSentry raised nearly $80 million in VC funding between 2004 and 2009, in VC funding, including a $9.4 million infusion just this past January. Backers included Accel Partners, DAG Ventures, Invesco Private Capital, Northgate Capital, Translink Capital and Vedanta Capital.
ConSentry shut its doors on August 20, but neither it nor its investors ever explained the failure. The only public comment came from company founder and chief scientist Mario Nemirovsky, who told Computer World that it was “a sad day.”
