NEWTON, MA – August 11, 2008 – ChosenSecurity, Inc., the leading provider of on-demand digital certificate management services, today announced $6 million in new financing to accelerate the company’s expansion as it continues to gain momentum in the on-demand certificate management market.

Funding will be used to capitalize on first-half momentum to accelerate North American and European sales, increasing the strategic investment in its infrastructure and new product offerings. The funding follows a highly successful first half for the company in 2008, with significant highlights in the following areas:

This funding, coupled with a strong subscription base from our SaaS model, will accelerate our momentum.”
