Imprivata

Imprivata, founded by David Ting, is helping business ditch user names and passwords. The company provides its enterprise-level customers with a variety of single sign-on methods--such as fingerprint analysis and smart identification cards--that employees can subsequently use to access various databases more quickly. Imprivata maintains that its authentication technology is secure, but could take a hit if any of its business customers were to experience a security breach. The security company's customers are primarily health care organizations, but Imprivata also works with banks, energy companies, and government organizations, and is exploring other highly regulated industries that it can service in the future. Note: employee count as of Dec. 31, 2015
