Sumsub sells identity verification, AML screening and fraud detection as one flow rather than three vendors. For an operator that matters because the three decisions are actually one decision: whether this person can open an account and move money.
The practical evaluation criteria are pass rate and time-to-verify by country, not the feature list. A verification vendor that is 4% better at catching fraud and 15% worse at approving legitimate Brazilian players will cost you more than it saves. Ask for measured pass rates on Brazilian documents specifically.
Sumsub covers many regulated industries beyond gambling. That breadth funds the document coverage, and it also means gambling-specific rules — self-exclusion register checks, for instance — need to be confirmed rather than assumed.
