Fraud Prevention

Fraud Prevention Starter Kit

We have released the Fraud Prevention Starter Kit — a predefined fraud risk package that turns onboarding signals, including email, phone, IP, device, identity data, and applicant linkages, into one actionable fraud risk level, using a pre-built matrix based on Sumsub's fraud detection experience.

This feature gives clients a practical way to start assessing applicant risk without building custom fraud rules or models from scratch, and targets new account fraud such as mule accounts, multi-accounting, bonus abuse, and synthetic identities.

User Verification

Automatic rejection after repeated failed attempts

Applicants who kept resubmitting after repeated failures used to hit a technical attempt cap after 69 tries, and were then referred to Sumsub support to resolve a limitation on our side.

Applicants are now automatically rejected as spam after 50 failed attempts. The system directs applicants back to the client's own support team, where a custom flow can help them complete verification if appropriate.

Rejection reason in resubmission emails

Resubmission emails now include the moderation comment explaining why an applicant needs to resubmit, helping applicants understand what went wrong and return to onboarding.

The comment appears formatted with line breaks and covers both applicant-level and document-specific rejections. Final rejection emails still send no comment, by design.

This update applies to both KYC and KYB applicants.

Dashboard

Device Check redesign

Device Check, part of the verification flow when Device Intelligence is enabled, now gives a clearer picture of device risk and why a device is flagged.

What is new:

• Device risk now factors in the number of connections and any links to fraudulent applicants.
• Medium-risk and high-risk labels use separate colors.
• An inline lookup shows linked applicants, with batch actions such as rejecting them all at once.
• A new Device Map View shows IP address geolocation.
• A Definite vs. Potential Match indicator shows confidence in connected applicants found.
• A new Checked Risk Labels section explains why a device is low risk and which checks ran, which varies by platform.

Self-purchasable steps in Level Settings

Clients can now purchase certain features directly from level configuration, without leaving the flow.

Self-purchasable steps appear in the Add step dropdown with a dedicated icon. Clicking one opens the purchase flow inline, and once the feature is enabled, the step is added to the level automatically.

Business Verification

New country in the KYB Local pack: Venezuela

Business verification now covers Venezuela, with data sourced directly from the Venezuela National Contractors Registry.

The integration returns company name, registration number, and legal form, and supports search by both company name and registration number.
