Boston Business Journal: Imprivata eyes IPO, adds Beth Israel's Halamka to board

Lexington-based Imprivata, a IT security firm focused on the health care industry, is expecting an initial public offering within two years after growing to more than $50 million in revenue in 2012, CEO Omar Hussain said in an interview. The venture-backed company also announced Tuesday that it has added two to its board of directors — Dr. John Halamka, the well-known chief information officer of Beth Israel Deaconess Medical Center, and Rodger Weismann, former CFO of Phase Forward (acquired by Oracle in 2010).
