About
Exterro is a legal governance, risk, and compliance (GRC) company that provides an integrated platform covering e-discovery, data privacy management, digital forensics, information governance, and legal hold. Headquartered in Portland, Oregon, and backed by private equity, Exterro has raised more than $100 million and has grown through organic product development and strategic acquisitions including Zapproved (legal hold), AccessData (digital forensics and incident response), and Kcura (former Relativity partner). The company serves corporate legal departments, law firms, and government entities that need a unified GRC platform spanning discovery, privacy, and compliance functions.\n\nExterro's differentiated positioning is its breadth across the legal GRC spectrum, offering not just e-discovery but also GDPR/CCPA privacy management, digital forensics for internal investigations and incident response, and information governance tools that help organizations manage data retention and defensible deletion programs. This comprehensive suite appeals to large corporate legal and compliance teams that want to consolidate vendors and manage the intersection of litigation, privacy, and compliance risk in a single platform with shared data and workflows.\n\nThe company competes with specialized vendors in each of its product categories — Relativity and DISCO in e-discovery, OneTrust and TrustArc in privacy management, Magnet Forensics and Cellebrite in digital forensics — and differentiates through integration across these functions. Exterro's PE backing has enabled it to invest in product development and make acquisitions that extend its platform, and the company continues to expand its customer base among Global 2000 corporations and government legal and compliance organizations.
