Sumsub sells breadth: KYC, KYB, AML monitoring and case tooling across jurisdictions in one account. Teams add or switch to TamperCheck when the actual requirement is depth on the document itself, without adopting a full compliance suite.
Why teams look for a Sumsub alternative
- You don't need KYC, KYB and AML monitoring - you need to know whether a specific document was altered or generated.
- Sumsub's document checks return pass/fail per verification, not an explanation an analyst can defend later.
- The monthly minimum ($149-$299) and per-verification pricing assume a compliance programme, not a lighter document-only need.

What switching gets you
- Forensic explainability without adopting a full compliance suite.
- No monthly minimum - $0.50 per document, however your volume moves.
- Managed AI inference under your control, not bundled into a broader platform bill.
When Sumsub is still the better fit
- You want one vendor for KYC, KYB, AML monitoring and regulatory coverage across markets.
- You need case management, analyst tooling and crypto-specific workflows built in.
Narrowing from a compliance suite to a document check
If Sumsub is your compliance backbone, the realistic move is adding TamperCheck alongside it for the documents that need forensic depth - proof of income, proof of address, invoices - rather than replacing your KYC/AML programme.
A full switch only makes sense if the actual workload was never compliance breadth to begin with - if you were paying Sumsub's monthly minimum just to check documents, a narrower per-document API is very likely cheaper and more direct.
Sumsub alternative: common questions
Can TamperCheck run alongside Sumsub?
Yes. Keep Sumsub for regulated onboarding and ongoing AML, and call TamperCheck on supporting documents where per-field tamper analysis and AI-generation detection do work a compliance workflow assumes is already done.
Is TamperCheck cheaper than Sumsub?
For document-only use cases, usually. Sumsub carries a $149-$299 monthly minimum plus $1.35-$1.85 per verification; TamperCheck has no monthly minimum and costs $0.50 per document. If you need the full KYC/AML suite, the comparison isn't like-for-like.
Does TamperCheck handle documents from any country, like Sumsub?
Yes - 100+ document types across 190+ countries, with no per-country configuration, because the analysis judges a document against its own internal consistency rather than a jurisdiction-specific template.
