Imprivata
A healthcare-focused digital identity and access security company.
Last updated August 26, 2026
Overview
Imprivata is a digital identity and access security company headquartered in Waltham, Massachusetts. Its business is concentrated primarily in healthcare, where clinicians, staff, contractors, and other users must reach many clinical and administrative systems while maintaining strong controls over authentication, authorization, privacy, and auditability. The company’s portfolio addresses this tension by combining single sign-on, multifactor and alternative authentication, identity governance, privileged access management, mobile-device access, and monitoring of access to sensitive patient information. The company was founded by David Ting and Phil Scarfo, who had worked on identity-management technology through a small-business incubator associated with Polaroid Corporation. Imprivata’s first commercial product was the OneSign Enterprise Single Sign-on appliance, which shipped in 2004. OneSign was designed to reduce the operational burden of repeated passwords and application logins while supporting stronger authentication methods. Its capabilities included access to enterprise applications without requiring extensive changes to existing directories or custom scripting, together with authentication options such as biometrics, proximity cards, smart cards, government or national identity cards, one-time-password tokens, and location-based controls. Centralized authentication and access-event records also supported compliance reporting. Imprivata expanded beyond its initial United States base during the mid-2000s. The company expanded into Europe, Africa, and the Middle East in 2005, and by 2006 it had established a broader European presence. Its technology leadership received external recognition when co-founder David Ting was named by InfoWorld among its leading chief technology officers in 2006. By 2017, the company reported more than 1,700 customers and offices across North America, Europe, and Australia. Healthcare organizations remained its principal customer group. The company broadened its platform through acquisitions. In 2009, it acquired assets of IdentiPHI, including the SAFsolution biometric-technology product line. In 2011, it acquired assets of Validus Medical Systems, whose technology was incorporated into Imprivata Cortext. These transactions expanded the company’s authentication, biometric, and secure communication capabilities. In 2019, Imprivata acquired GroundControl to strengthen its mobile offerings. In 2020, it acquired FairWarning, adding technology associated with digital-identity protection and patient-privacy monitoring. It subsequently acquired Xton Technologies and SecureLink, extending its capabilities into privileged access management for both internal users and external parties. Imprivata became a public company on June 25, 2014, with its shares listed on the New York Stock Exchange. Its public-company period ended in 2016, when private-equity firm Thoma Bravo acquired the company. The transaction was announced at a price of $19.25 per share and was reported at an estimated total value of $544 million. Omar Hussain was chief executive when the transaction was announced. Imprivata is now positioned as a specialized identity-security provider for complex, highly regulated environments, particularly healthcare, where secure access must coexist with clinical speed, shared workstations, mobile workflows, privacy obligations, and extensive third-party access.
History
Imprivata originated in identity-management work developed by David Ting and Phil Scarfo while they were associated with Polaroid Corporation’s small-business incubator. The founders established the company around the need to simplify secure access to enterprise applications without forcing organizations to redesign their existing application environments. Its first commercial product, the OneSign Enterprise Single Sign-on appliance, reached the market in 2004. OneSign provided a central mechanism for managing user authentication and application access. In addition to reducing repeated password entry, the system supported stronger authentication methods including fingerprint biometrics, proximity cards, smart cards, government and national identity cards, one-time-password tokens, and location-based authentication. Consolidated access records could also assist organizations with compliance reporting. These capabilities were particularly relevant to healthcare institutions, where staff often move among shared workstations and numerous clinical systems under strict privacy and security requirements. Imprivata began international expansion in 2005, reaching Europe, Africa, and the Middle East, and expanded its European presence further in 2006. In that year, co-founder David Ting was recognized by InfoWorld as one of its leading chief technology officers. By 2017, Imprivata had more than 1,700 customers and offices in the Americas, Europe, and Australia. Its customer base was primarily made up of healthcare organizations. The company used acquisitions to broaden its identity and access portfolio. In 2009, it acquired assets of IdentiPHI, a biometric-technology manufacturer and reseller, including the SAFsolution line. In 2011, it acquired assets of Validus Medical Systems of Santa Cruz, California; those assets were incorporated into Imprivata Cortext. The company later pursued mobile, privacy, and privileged-access opportunities. GroundControl was acquired in 2019 to expand mobile capabilities, while FairWarning was acquired in 2020 to strengthen the company’s digital-identity and patient-privacy offering. Acquisitions of Xton Technologies and SecureLink subsequently extended the platform into privileged access management for internal employees, vendors, contractors, and other external users. Imprivata entered the public markets on June 25, 2014, when it became listed on the New York Stock Exchange. The public-company phase ended in 2016 after Thoma Bravo agreed to acquire the business. The announced consideration was $19.25 per share, with an estimated transaction value of $544 million. Omar Hussain was chief executive at the time. Under private ownership, Imprivata continued to be described as a digital identity security company with a strong healthcare orientation. Its overall development reflects a progression from enterprise single sign-on and authentication toward a broader platform covering identity governance, mobile access, privacy monitoring, and privileged access management.
