Choosing a document verification partner is a significant decision. These pages help procurement and operations teams understand how TamperCheck compares to the tools they're evaluating — on pricing, privacy posture, and what it actually takes to get started. Note that TamperCheck works on digital PDFs and scanned hard copies alike — including physical stamp verification and handwritten signature analysis, not just native digital files.

TamperCheck vs Sumsub: tamper API vs. full compliance & verification platform

TamperCheck is a focused document fraud API with BYOK and simple economics. Sumsub is a broad compliance platform—KYC, KYB, transaction monitoring, crypto travel rule—where document checks sit inside a much larger verification and AML story.

Transparent pricing: TamperCheck publishes $0.50 per document after your $5 credits — pay-as-you-go, no seat fees, no opaque tiers. Full pricing →

When to choose TamperCheck

  • You need deep tamper explainability and BYOK without adopting a full compliance suite.
  • You’re a product/engineering team pricing a single API—not procuring enterprise KYC for 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. forensic microservice

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 BYOK, 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.
