A prop firm's KYC problem looks different from a broker's. Thousands of people can buy an evaluation without ever being asked for a document, because most challenge purchases run on demo accounts with no deposit and no client money to protect. The identity check only becomes mandatory the moment someone passes and a payout is due, which means a firm can go from zero verified traders to hundreds needing a check in the same week a cohort of challenges completes. That timing, plus the incentive to game a funded account, makes the KYC choice for a prop firm about speed at volume and about catching one person behind several funded accounts, more than about the broad country coverage a retail broker worries about first.
This piece compares the same four named vendors as our broker guide, Sumsub, Onfido (now part of Entrust as Entrust Identity Verification), Veriff and Jumio, but from the prop firm's angle: onboarding a payout cohort fast, and stopping multi-accounting before a payout goes out twice. What we describe comes from what each vendor publishes; we have not run our own side-by-side test. SGHK's Prop Firm CRM integrates any of these by API, including manual review as a fallback, so the choice here is between vendors, not a pitch for one over the others.
Why prop firm KYC timing is different
A retail broker verifies a client before the first deposit. A prop firm typically verifies a trader only at payout, after they have passed an evaluation on a demo account, which means the KYC vendor has to absorb a spike rather than a steady trickle. If your firm runs monthly challenge cohorts, a batch of a few hundred traders can all need a check in the same 48 hours. A vendor's average verification time matters more here than its raw country count, because a slow queue at payout time is what turns into support tickets and public complaints about withheld payouts.
The short version
| Vendor | Speed at volume | Multi-accounting detection | Notable for a prop firm |
|---|---|---|---|
| Sumsub | Around 20 seconds average verification across 14,000+ document types and 220+ countries and territories | Device Intelligence reads browser, hardware and network signals to flag the same device or network behind more than one account | Non-documentary verification and video identification as extra paths when a document scan stalls |
| Onfido (Entrust) | Document and biometric checks with orchestration across data sources | Liveness detection built to catch deepfakes, video injection and masks | Now sold as Entrust Identity Verification following Entrust's 2024 acquisition of Onfido |
| Veriff | Around 6 seconds average verification, 98% check automation, across 12,500+ documents and 230+ countries and territories | Fraud Protect blocklists by face, device and network; IP and device fingerprinting to link accounts | Passive liveness with no head turns or blinking required, useful for a mobile-heavy trader base |
| Jumio | Document authentication and biometric selfie match, over 1 billion identity verifications processed on its own figures | Computer vision forgery and tamper detection, including physical tampering such as hole punches | Multiple integration paths (iOS, Android, API, SDK, webcam, SMS) for firms with traders on different devices |
1. Sumsub
Sumsub's headline figures are 14,000+ document types across 220+ countries and territories, at an average verification time it puts around 20 seconds. For a prop firm, two features matter beyond the basic document check. Non-documentary verification cross-checks a trader's identity data against government or other databases rather than requiring a document photo, which helps when a payout queue is backed up and a trader's phone camera is the bottleneck. Device Intelligence reads browser, hardware and network-level signals to recognize the same device or network across sessions, which is the mechanism a firm would actually use to catch one trader funding several evaluation accounts under different names to multiply payouts.
2. Onfido, now Entrust Identity Verification
Entrust completed its acquisition of Onfido in 2024, and the identity verification technology now trades as Entrust Identity Verification. It combines document verification, biometric face matching and liveness detection built to catch deepfakes, video injection and masks, and it can chain document, biometric and data-source checks into one flow. A prop firm already under an Onfido contract should confirm current terms and support channels under the Entrust name, since the standalone Onfido brand is being retired.
3. Veriff
Veriff publishes 230+ countries and territories and 12,500+ supported documents, with an average verification time around 6 seconds and a 98% check automation rate on its own figures. Its liveness check is passive, meaning a trader does not have to turn their head or blink on command, which matters when your funded traders are verifying from a phone between trading sessions rather than at a desk. Veriff's fraud analysis draws on more than 1,000 device, network and behavioral data points per check, and its Fraud Protect package blocks a returning bad actor by face, device or network, which is the direct answer to a trader who was already caught gaming one funded account and tries to come back under a new email for a second one.
4. Jumio
Jumio covers more than 5,000 physical and digital ID document types across 200 countries and territories, and it authenticates a document by checking security features such as holograms, fonts and machine-readable zones before comparing a live selfie to the photo. Its computer vision is built to catch forgery and tampering that some scanners miss, including hole punches on a physical licence or passport, a detail that matters if your firm still accepts an older or worn document from a trader in a market where digital ID is not universal. Jumio publishes over 1 billion identity verifications processed and supports integration through iOS and Android SDKs, a web API, webcams and SMS-based flows, useful for a prop firm whose traders sign up from a mix of devices and regions.
The one-person, many-accounts problem
The single biggest KYC-adjacent risk for a prop firm is not a fake document, it is one real person running several funded accounts to draw multiple payouts from what should be one evaluation. Document and biometric checks alone do not catch this, because each account can carry a genuine document from a genuine person, just the same person twice. This is where device fingerprinting and network analysis do the actual work: Sumsub's Device Intelligence and Veriff's Fraud Protect blocklists are both built around linking accounts by device and network signals rather than by document content. Ask any vendor you evaluate to show this specific capability rather than stopping at their document pass rate, since it is the feature a prop firm's rules engine actually depends on.
Where this fits with the rest of your rules engine
KYC at payout is one control among several a prop firm runs: consistency checks, prohibited-strategy detection, drawdown and profit-target rules all sit alongside it. See prop firm rules engines compared for how those pieces work together, and KYC verification levels for how firms typically tier a demo-stage check against a full payout-stage check. SGHK's Prop Firm CRM runs the rules engine and the payout flow in one place and connects to Sumsub, Onfido, Veriff or manual review by API, so the KYC vendor decision does not have to be made at the same time as the CRM decision.
How to choose
Model your actual payout cadence before you sign anything: if your biggest evaluation cohort clears on the same day each month, ask each vendor what their queue and pass rate look like at that volume, not their average across a steady trickle of applicants. Confirm device or network fingerprinting is included, since that is the control most directly tied to stopping duplicate funded accounts. And keep manual review as a fallback for the edge cases every automated vendor will occasionally miss. Book a call if you want to see how a KYC vendor connects into the Prop Firm CRM's payout flow.
"A prop firm's real KYC test is not the first document, it is catching the same trader behind a second funded account. That is a device and network problem as much as a document one."

Key Takeaways
- Prop firm KYC usually happens at payout, not signup, so a vendor's speed under a cohort spike matters more than its average across a steady trickle.
- Document and biometric checks alone do not catch one trader running several funded accounts; device and network fingerprinting does.
- Sumsub's Device Intelligence and Veriff's Fraud Protect blocklists are both built to link accounts by device and network signals.
- SGHK's Prop Firm CRM connects to any of these vendors, or manual review, by API, so the KYC choice stays independent of the CRM choice.
Frequently Asked Questions
When should a prop firm run KYC, at signup or at payout?
Most prop firms verify identity when a payout is due rather than at evaluation signup, since evaluations typically run on demo accounts with no client money involved. Some firms add a lighter check earlier to deter obvious fraud. Either way, plan for the check to arrive in a spike tied to your challenge cohort schedule, not a steady daily trickle.
How do KYC vendors stop one trader from running multiple funded accounts?
Document and selfie checks alone will not catch this, since a genuine person's real document passes every time even on a second or third account. Device fingerprinting and network analysis, such as Sumsub's Device Intelligence or Veriff's Fraud Protect blocklists, link accounts by browser, hardware and network signals instead, which is the mechanism that actually flags a repeat trader.
Is Onfido a good option for a prop firm in 2026?
Onfido's identity verification technology is now sold as Entrust Identity Verification, following Entrust's 2024 acquisition of Onfido. The underlying document, biometric and liveness checks are the ones to evaluate; confirm current contract terms under the Entrust name.
Can a prop firm use more than one KYC vendor?
Yes, and some firms do, using an automated vendor for most payouts and manual review for flagged or unusual cases. SGHK's Prop Firm CRM connects to Sumsub, Onfido, Veriff or manual review by API, so a firm is not limited to one vendor across its whole payout flow.
