When to choose TamperCheck
- You need deep tamper explainability and managed AI inference without adopting a full compliance suite.
- You want to budget for document verification on its own - not procure an enterprise KYC programme covering every geography at once.
When to choose Sumsub
- You want one vendor for KYC, KYB, AML monitoring, and regulatory coverage across markets.
- You need analyst tooling, case management, and crypto-specific workflows out of the box.
Compliance platform vs. specialist document forensics
Sumsub’s strength is breadth: many check types, jurisdictions, and product lines in one account. TamperCheck’s strength is depth on the document: forensic layers, AI adjudication with and an API that doesn’t pretend to be your entire compliance department.
Choose Sumsub when you’re building programmatic compliance. Choose TamperCheck when you’re trying to win arguments about suspicious uploads with structured evidence-and keep AI costs under your provider contract.
TamperCheck vs Sumsub: common questions
What is the best Sumsub alternative for document verification?
TamperCheck.ai, when the requirement is forensic depth rather than compliance breadth. Sumsub covers KYC, KYB and AML across jurisdictions; TamperCheck does one thing thoroughly - proving whether a document was altered or generated - and names the specific field rather than returning a platform-level decision.
Can TamperCheck run alongside Sumsub?
Yes. Keep Sumsub for regulated onboarding and ongoing AML, and call TamperCheck on the supporting documents - proof of income, proof of address, invoices, certificates - where per-field tamper analysis and AI-generation detection do the work a compliance workflow assumes has already been done.
Does TamperCheck handle documents from any country?
Yes - 100+ document types across 190+ countries, with no per-country configuration. The analysis is template-free, comparing each field against the rest of its own page, so a document from an issuer never seen before is analysed to the same standard as a familiar one.
