Most identity verification platforms do one thing well: they check documents and match faces. When you need AML screening, you add another vendor. Transaction monitoring? Another vendor. KYB for business onboarding? Yet another. Before long, your compliance stack is a patchwork of five or six tools, each with its own dashboard, API, pricing model, and support team. Sumsub's claim is that you can replace all of them with a single platform — and that claim largely holds up.
Sumsub is an all-in-one verification platform covering KYC (Know Your Customer), KYB (Know Your Business), AML/PEP/sanctions screening, transaction monitoring, fraud prevention, and regulatory reporting. Founded in 2015 and headquartered in London, the company serves over 2,000 clients across fintech, crypto, gaming, transportation, and marketplace sectors. The platform covers 220+ countries and territories with 14,000+ supported document types.
What sets Sumsub apart from pure identity verification providers like Onfido or Veriff is breadth. Those platforms excel at document and biometric verification. Sumsub does that too, but then extends into transaction monitoring, ongoing due diligence, business verification, and fraud prevention — creating a unified compliance layer that spans the entire customer lifecycle, not just the onboarding moment.
The platform is accessible to non-technical teams through a no-code workflow builder, while developers get full API and SDK access. A free tier with 50 verifications makes it one of the most accessible platforms in the space for evaluation. The trade-off for this breadth is complexity — the dashboard and configuration options can overwhelm teams with simpler needs.
Sumsub handles both individual identity verification (KYC) and business verification (KYB) within a single platform. KYC covers document verification, biometric matching, liveness detection, and data extraction across 14,000+ document types. KYB adds company registry checks, UBO (Ultimate Beneficial Owner) identification, and corporate document verification. Having both in one platform eliminates the need to stitch together separate KYC and KYB providers.
Sumsub's workflow builder is a drag-and-drop visual tool that lets compliance teams design verification flows without developer involvement. You can create conditional paths — for example, require enhanced due diligence for high-risk countries, skip biometric checks for low-risk transactions, or trigger manual review for edge cases. The builder supports complex multi-step journeys and integrates all of Sumsub's verification capabilities.
This is a significant differentiator. Compliance requirements change frequently as regulations evolve, and the ability to modify verification flows without a development sprint saves weeks of engineering time.
Beyond initial verification, Sumsub monitors ongoing transaction patterns to detect suspicious activity. The rule engine supports custom risk scoring based on transaction amounts, frequency, geography, and behavioural patterns. Alerts can trigger enhanced verification, account freezes, or Suspicious Activity Reports (SARs).
Integrated screening against global watchlists, PEP (Politically Exposed Persons) databases, and sanctions lists runs automatically during verification and can be configured for ongoing monitoring. This eliminates the need for a separate AML screening vendor and ensures that screening results are linked directly to the user's verification profile.
Sumsub includes device fingerprinting, velocity checks, and behavioural analysis to detect fraud patterns. The crosslinking feature identifies when the same person attempts to verify with different identities across your platform or across Sumsub's network. This network-level fraud detection is only possible because of Sumsub's scale across 2,000+ clients.
Sumsub's reusable verification feature allows users to complete identity verification once and share the result across multiple platforms that use Sumsub. This reduces friction for end users and improves conversion rates, while ensuring verification standards are maintained.
Sumsub is one of the few identity verification platforms that offers a genuine free tier — 50 verifications at no cost, with access to core features. This makes evaluation and proof-of-concept work possible without sales engagement, which is unusual in the enterprise-focused KYC market.
Beyond the free tier, Sumsub uses pay-per-verification pricing with volume discounts. The Growth tier offers standard verification at competitive per-check rates, while the Business tier adds transaction monitoring, dedicated account management, and priority support at custom pricing. Enterprise agreements include custom SLAs, on-premise deployment options, and regulatory consulting.
Pricing scales with volume, and high-volume customers report that costs can accumulate significantly. The all-in-one value proposition needs to be evaluated against the total cost of separate point solutions — in many cases, Sumsub's bundled approach is more economical, but this depends on your specific verification mix and volume.
Sumsub offers EU data processing and storage options, with ISO 27001 and SOC 2 Type II certifications. The platform supports GDPR compliance with configurable data retention policies, user deletion capabilities, and data processing agreements.
However, Sumsub is a UK-headquartered company with global operations. Post-Brexit, the UK operates under its own data protection framework (UK GDPR), and while the EU has granted the UK an adequacy decision, this is not permanent and can be revoked. For organisations with strict EU data sovereignty requirements, the UK corporate jurisdiction is a consideration — though not a disqualifier.
Sumsub's support for regulatory frameworks like MiCA (Markets in Crypto-Assets) and 6AMLD (Sixth Anti-Money Laundering Directive) is relevant for crypto and financial services clients navigating evolving European regulation.
Fintech and crypto companies that need KYC, AML, and transaction monitoring in a single platform. Sumsub's all-in-one approach eliminates vendor sprawl in heavily regulated sectors.
Compliance teams without developer resources who need to build and modify verification flows using the no-code workflow builder. The visual tools make Sumsub accessible to non-technical staff.
Companies operating across multiple jurisdictions (220+ countries) that need a single platform covering diverse document types and regulatory requirements.
Startups evaluating identity verification who want to test with the free tier before committing. The 50 free verifications lower the barrier to entry significantly.
Sumsub delivers on its all-in-one promise more convincingly than any competitor in the identity verification space. The combination of KYC, KYB, AML screening, transaction monitoring, and fraud prevention in a single platform genuinely reduces vendor complexity and compliance overhead. The no-code workflow builder and free tier make it accessible, while the API and SDK depth satisfy developer teams. The trade-off is dashboard complexity and UK corporate jurisdiction — but for most regulated businesses, the unified approach is worth both.
Yes. Sumsub provides 50 free verifications with access to core features including document verification, biometric matching, and the workflow builder. No credit card is required. This makes it one of the most accessible identity verification platforms for evaluation.
Sumsub is an all-in-one platform covering KYC, KYB, AML screening, transaction monitoring, and fraud prevention. Onfido and Veriff focus primarily on document and biometric verification. If you need only identity checks, any of the three work. If you need a unified compliance platform, Sumsub covers significantly more ground.
Yes. Sumsub offers EU data processing options and is ISO 27001 and SOC 2 Type II certified. As a UK company, it operates under UK GDPR, which currently has EU adequacy status. Data can be stored in EU data centres.
