Sumsub launches fraud prevention starter kit

Sumsub has launched a Fraud Prevention Starter Kit that converts signals gathered during onboarding into a single risk level and assigns one of four actions: approve, step-up, review or block. The product is entering a closed launch with limited initial availability.

The kit collects onboarding context such as email and digital footprint, phone risk, IP and network indicators, device intelligence, identifiers repeated across applicants, and confirmed fraud feedback and blocklists. These inputs can be captured through Sumsub’s verification flows, its WebSDK and MSDK, API or pre‑KYC integrations.

Collected signals feed a pre-built risk matrix that weights individual factors, runs cross-consistency checks, applies device and network intelligence, maps connections between applicants and flags known fraud patterns. Each applicant is scored low, medium or high, and the outcome can be forwarded automatically into downstream workflows.

Sumsub’s internal data show the global identity fraud rate fell from 2.6% to 2.2% over the past year while attacks that combine several techniques in a single verification attempt rose 180%. The company reports that many successful attempts now pass identity checks and appear through new markets, referral programmes and growth campaigns as fake accounts, mule accounts and multi‑accounting.

Know‑your‑customer checks confirm identity but do not determine whether an applicant is safe to trust. Building an in‑house fraud function typically requires months of design, testing and tuning plus additional hires, a gap the company says exposes fast‑growing businesses during rapid expansion.

Sumsub positions the Starter Kit as a ready‑made starting point: teams begin with predefined logic and can change rules, thresholds and workflows as their fraud operations mature. For organisations with existing fraud functions, the kit can supply extra onboarding signals and richer applicant context to supplement current processes.

Andrew Novoselsky, chief product officer at Sumsub, described the Starter Kit as a way to provide a working fraud decision on day one and a base for ongoing improvement. The system also links new applicants to known bad actors when they share devices, contact details or other identifiers with confirmed fraudulent accounts; those connections affect later risk assessments.

The closed launch will limit initial availability while Sumsub collects feedback and refines the product.
