Sumsub covers a lot of ground. Its Non-Doc Verification page lists:
- Products: ID verification, liveness and deepfake detection, non-document verification, reusable KYC, transaction monitoring, crypto monitoring, Travel Rule, workflow orchestration and case management.
- Speed: its non-document check verifies identity in 4.5 seconds against government, banking and credit sources.
- Audit: FINTRAIL audited the offering for compliance in 20 or more countries.
Breadth is the reason it lands on shortlists.
The reasons teams leave come from other vendors' framing, so read them as such:
- Pricing tied to plans: Allpass.ai's article on Sumsub alternatives, drawing on G2 reviews, says some features such as AML screening and ongoing monitoring sit on higher Sumsub plans, so a team can end up upgrading for one feature.
- Complexity for non-technical staff: the same Allpass.ai article reports reviewers describing a steep learning curve and compliance logic that is hard to interrogate when an auditor asks why a decision went the way it did.
- A shift in the job: AiPrise's guide to Sumsub alternatives names four triggers: business verification becoming the main workload, documents no longer being enough against generated fakes, the full lifecycle mattering more than the onboarding flow, and expansion out of the first vertical.
One trigger neither article covers is that onboarding checks do not stop account resale.
An account that passed KYC can be sold with the passport, selfie and bank account already attached. The original holder passes every onboarding check because they are real.
The control that catches the handover is a fresh face match, compared against the person who onboarded:
- At the first withdrawal.
- On a new device.
- At a payout change.
That is a check at the moment of action, and it is the gap this page is organized around.
