Thoma Bravo, a software investment firm, has made an additional strategic investment in its portfolio company Imprivata, a digital identity company for mission- and life-critical industries. The investment will be used to fund Imprivata’s previous acquisition of SecureLink.

Thoma Bravo initially acquired Imprivata in September of 2016 and has since supported the firm through operational, strategic, and sector expertise to continue advancing the firm’s growth as a provider of digital privacy. Going forward, Imprivata and SecureLink will provide a single source to enable and protect digital identities for enterprise and third-party customers.

“Our long-term partnership with Imprivata reflects our passionate belief in the business-enabling power of security in the digital future,” said Scott Crabill, a managing partner at Thoma Bravo. “With the addition of SecureLink’s capabilities, Imprivata is creating a new class of cybersecurity providers that unlocks digital freedom across platforms and applications by seamlessly securing identity interactions at every access point.”
