Executive Summary
ZoomInfo (formerly DiscoverOrg) is a publicly-traded B2B intelligence platform headquartered in Vancouver, WA. While marketing as a business data provider, ZoomInfo is officially registered as a California data broker and explicitly sells personal information including names, emails, and phone numbers. Despite claiming SOC2 Type II, ISO 27001, and GDPR/CCPA compliance, BLACKOUT runtime scans detect ZoomInfo on 60 websites with a 26.6% pre-consent firing rate, indicating systematic tracking before user consent. This creates material compliance gap between their certifications and actual runtime behavior.
Revenue Threat Profile
4 COLLAPSE VECTORSHow this vendor creates financial exposure. Each score (0-100) reflects observed runtime behavior and documented business practices.
CAC Subsidization
ZoomInfo corrupts measurement by harvesting contact data from email integrations and third-party sources, creating shadow profiles that influence sales targeting without accurate consent provenance. Organizations using ZoomInfo-sourced leads may be making decisions based on data obtained through undisclosed collection methods.
Signal Corruption
As a registered data broker, ZoomInfo aggregates and resells business contact information to competitors and third parties. Companies whose employees appear in ZoomInfo database effectively leak demand signals - who they are hiring, their tech stack, growth patterns - to anyone paying for access.
Legal Tail Risk
ZoomInfo creates attack surface through extensive data aggregation. Their database of 300M+ business professionals provides reconnaissance value to threat actors. The 26.6% pre-consent tracking rate exposes client websites to regulatory enforcement risk.
GTM Attack Surface
Critical consent liability: ZoomInfo claims GDPR and CCPA compliance while operating as a registered data broker with documented pre-consent tracking. California AG registration confirms personal data sales. Organizations using ZoomInfo face vicarious liability for their data collection practices.
