Sumsub provides identity verification for online services that must know who their customers are. A user photographs an ID document and takes a selfie, and Sumsub checks that the document is real, matches the person, and that a live person is present, which helps block stolen identities and deepfakes. Results come back in seconds or minutes.
Beyond onboarding, the platform covers compliance. It screens users against sanctions and politically exposed persons lists, monitors transactions for suspicious behavior, and supports business verification for companies. Fraud prevention features detect fake documents, duplicate accounts, and bots, and a case management dashboard lets compliance staff review flagged applicants.
Sumsub is sold per verification and by plan, to companies in fintech, crypto, gaming, and marketplaces across many countries. Strict verification can cause some legitimate users to drop out, and requirements differ by jurisdiction. Competitors include Onfido (Entrust), Persona, Jumio, Veriff, and Socure. Sumsub suits regulated businesses that onboard customers online.
