Identity verification that stops deepfake impersonation and account takeover
Detects AI-generated faces, synthetic video and digital injection attacks during the identity verification flow so that a stolen photo or deepfake cannot pass as a live employee or customer.
A mobile-native verification experience that confirms the person in under 30 seconds, with a returning-user path that re-verifies via a single selfie.
Verifies callers before agents act on password or MFA resets, and lets verified users perform their own resets under customizable group-based permissions.
Connects to Okta, Microsoft Entra ID, Duo, Cloudflare, ServiceNow, Zendesk, Workday, Greenhouse and Beyond Identity to create a persistent verified identity across systems.

Privacy-first bot detection and fraud prevention for the web
Multi-layered detection delivers risk scores and near-zero false positives, with passive and no-CAPTCHA modes.
Stop transaction fraud, account takeovers and multi-accounting with privacy-preserving signals and no PII.
A stronger, toll-free alternative to SMS MFA that reduces fraud while simplifying the user experience.
Build custom risk models with adaptive learning and enrich your own ML using blinded, compliant signals.
