Every serious trading firm ends up asking the same question: Sumsub, Onfido or Veriff? All three are mature, widely deployed identity-verification platforms that will check documents, match faces and flag fraud competently. Choosing between them is less about "which one works" and more about scope, automation philosophy, geography and price structure — and, just as importantly, about not letting the choice calcify into your infrastructure.
Here is an honest comparison from the perspective of a prop firm or broker, followed by the architectural point most firms learn too late: the provider should be a plug, not a foundation.
What a KYC Provider Actually Does for You
Strip the branding and all three deliver the same core loop: a trader submits a government ID and a selfie; the provider checks document authenticity, matches the face, screens against watchlists where configured, and returns an approve, reject or review verdict. The differentiators live around that loop — how many document types and countries are covered, how much of the verdict is automated versus human-reviewed, what fraud signals are consulted, and how the pricing scales with your volume.
For a trading firm, KYC is not paperwork theatre. It's the gate in front of money: in the Singuard Prop Firm CRM and Broker CRM, no payout or withdrawal moves without a verified identity. Your provider choice determines how fast and how accurately that gate opens for legitimate traders — and stays shut for the rest (see identity fraud in prop firms).
The Three, Fairly
Sumsub — The Broad Platform
Sumsub positions itself as an all-in-one verification platform: document and biometric KYC, AML screening, ongoing monitoring and case-management tooling in one place. Its document and country coverage is among the widest in the market, which matters for firms selling globally — a prop firm's buyers can arrive from anywhere, with anything from a passport to a regional ID card. The trade-off of breadth is that you're adopting a platform, not just a check; firms that only need the core loop may not use half of what they're paying for.
Onfido — The Enterprise Document-and-Biometric Specialist
Onfido, now part of Entrust, built its reputation on document verification and facial biometrics, with heavy investment in machine-learning fraud detection and a long enterprise client list in banking and mobility. It's a strong choice for firms that want a specialist with an enterprise pedigree. The considerations: enterprise focus can mean enterprise-style onboarding and pricing, which a lean two-person launch team should weigh against its actual volume.
Veriff — The Automation-First Engine
Veriff leans hardest into automated decisioning — fast verdicts driven by device and behavioural signals alongside the document itself, with strong video-based capture. For a prop firm optimising signup-to-purchase conversion, decision speed is genuinely valuable: every hour a trader waits for verification is an hour to change their mind. The consideration is the mirror image: heavily automated flows must be tuned so legitimate edge cases (worn documents, older devices) route to review rather than rejection.
| Sumsub | Onfido | Veriff | |
|---|---|---|---|
| Character | Broad all-in-one platform | Enterprise document + biometric specialist | Automation-first decision engine |
| Standout | Coverage breadth; KYC + AML + monitoring in one | Mature ML fraud detection; enterprise pedigree | Decision speed; strong automated capture |
| Weigh up | Platform scope you may not fully use | Enterprise-style onboarding and pricing | Tuning needed for edge-case documents |
| Best fit | Global firms wanting one vendor for KYC + AML | Firms prioritising a specialist with bank-grade references | Conversion-focused firms optimising time-to-verified |
The honest summary: none of the three is a mistake. Match the provider to your geography, volume and appetite for platform breadth — and revisit the choice as your firm grows, because the right answer at 100 traders and at 10,000 traders may differ.
The architectural point: in the Singuard CRMs, Sumsub, Onfido, Veriff — or virtually any identity provider you prefer — connect in one click via the integrations hub. Switching providers later is a configuration change, not a migration project. Choose freely, because you're never locked in.
The Fourth Option: Manual Review
Both CRMs also support manual document review — traders upload IDs privately (never on a public link), and your compliance staff approve or reject each document with recorded reasons in a review queue. Manual review makes sense at low volume, in niches where automated providers underperform, or as the fallback lane behind an automated provider. Many firms run hybrid: automated verification for the 95% of clean cases, manual review for the rest. Every decision — automated or human — lands in the same permanent audit log.
What Matters More Than the Logo on the Check
Whichever provider you pick, the outcomes that protect your firm come from how KYC is wired into the platform, not from the provider brand:
- Identity gates money, structurally. No verified identity, no payout — enforced by the server, not by staff memory.
- Verdicts flow automatically. Approval unlocks the trader's next step without a human copying statuses between dashboards.
- Everything is recorded. Who was verified, when, by which method, and who overrode what — a permanent, searchable record (see audit trails).
- KYC is one gate of several. It sits alongside KYB for your own firm's onboarding (KYB explained) and your broader obligations covered in AML basics.
And to keep responsibilities clean: Singuard is a software-only vendor. It wires your chosen provider into your workflows — your firm owns its compliance program, its provider contract and its decisions.
"The best KYC provider is the one your actual clients pass smoothly. Choose by market coverage first, price second."

Key Takeaways
- Sumsub, Onfido and Veriff are all credible — they differ in breadth, enterprise focus and automation philosophy, not in basic competence.
- Match the provider to your geography, volume and conversion goals — and re-evaluate as you scale.
- The Singuard CRMs connect any of them — or manual review — in one click, so the decision is reversible configuration, not architecture.
- The protection comes from the wiring: identity gates payouts server-side, verdicts flow automatically, and every decision is audit-logged.
Frequently Asked Questions
Which KYC Provider Is Best for a New Prop Firm?
For most new firms, start with whichever provider best covers your buyers' countries and gives you acceptable per-check economics at low volume — then let real rejection and conversion data guide you. Because the CRM connects any provider in one click, an early choice is never a permanent one.
Can I Start with Manual KYC Review and Add a Provider Later?
Yes. Manual review is fully supported — private uploads, a compliance queue, recorded approval and rejection reasons — and you can wire in Sumsub, Onfido, Veriff or another provider whenever volume justifies it, without changing your workflows.
Does Singuard Do the KYC Itself?
No. Singuard provides the software that integrates your chosen identity provider (or your manual process) into onboarding, payouts and the audit log. The compliance program, the provider relationship and the verification decisions belong to your firm.
