Entrust

Global leader in digital identity, credentialing, and PKI-based security solutions; adjacent to AdTech through identity verification and authentication infrastructure

Entrust is a Minneapolis-based cybersecurity and digital identity company with deep roots in PKI (Public Key Infrastructure), digital certificates, identity verification, and secure credentialing. Founded in the late 1990s, Entrust has grown through acquisitions to become a comprehensive provider of identity-centric security solutions spanning consumer authentication, enterprise IAM, document security, and payment card issuance. The company serves governments, financial institutions, healthcare organizations, and enterprises globally. In the context of AdTech, Entrust's relevance stems primarily from its identity and authentication infrastructure, which underpins trusted digital transactions and user verification — capabilities increasingly important in a privacy-first, cookieless advertising ecosystem. Its acquisition of companies in the identity verification and digital trust space has expanded its footprint into areas adjacent to AdTech, including consent management, fraud prevention, and authenticated identity signals. Entrust operates as a private company (having been taken private and later acquired by Thales Group in 2019, though it continues to operate under the Entrust brand). With thousands of customers across 150+ countries, Entrust holds a strong market position in digital trust infrastructure, making it a significant player in the broader ecosystem of authenticated, privacy-compliant digital identity that modern AdTech increasingly depends upon.
