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.

Verify income, identity, and documents before you hand over the keys
Applicants connect bank and payroll accounts through Plaid so earnings are read from the account itself, with no document in the path to forge. Uploaded documents are also analyzed for deposit frequency and real income.
A government ID photographed front and back is matched against a live selfie using facial recognition, catching borrowed identities before keys are handed over.
Uploaded PDFs are read at the byte level for hidden text layers, metadata mismatches, generator fingerprints, and post-generation edits — evidence that visual inspection misses.
Each application returns one of five verdicts (pass, pass with caution, non-recurring, needs review, fail) with a risk level and the specific signals that produced it.
