Analyze web presence

Evaluate a business’s web presence quality through automated analysis of their website’s content, domain ownership, compliance information, and other indicators.

Verify business industry classification

Analyze a business’s name, address, and optional website URL to confirm that they do what they claim to do.

Evaluate email risk

Evaluate email addresses submitted on a business and surface risk signals — validity, deliverability, domain reputation, breach exposure, and more — before onboarding.
