Sumsub alternatives: Comparing 8 identity verification solutions

High drop-off during onboarding often comes down to one metric: match rate. If your verification system fails to match genuine applicant data on the first try, your users could end up in manual review queues – or walk away to a competitor. Therefore, your challenge is maximizing first-time pass rates without compromising security or regulatory standards.

But security and compliance are only part of the equation. Plug-and-play Know Your Customer (KYC) tools often work fine when you’re starting out, but as you scale, rigid rules and surface-level data checks can stall growth. 

This is where risk orchestration comes in: you can apply different verification rules and  thresholds depending on factors like geography, transaction type, or customer risk level instead of putting everyone through the same one-size-fits-all journey.

In this article, we compare seven leading Sumsub alternatives to help you select the best identity verification solution for your business. We’ll cover:

• GBG
• Persona
• Veriff
• Entrust
• Jumio
• Shufti Pro
• Trulioo

Higher match rates mean fewer manual reviews, less friction, and more genuine customers making it through onboarding. Book a demo to see how our end-to-end identity verification solution, GBG Go, can help you get there.

GBG: Tailored identity verification for high-risk industries

If you’re operating in a tightly controlled industry, standard verification tools may not be able to keep pace with your risk exposure or compliance regulations. You likely need a verification system built around your specific requirements.

With more than three decades of identity verification experience across gaming, financial services, and other regulated industries, we’ve built our platform around complex verification and compliance demands. Trusted by tier-one banks and FCA-regulated institutions, we often work with clients that adhere to high compliance standards.

As the author of this post, we’ll introduce ourselves before diving into other leading alternatives to consider. Here are three reasons 20,000+ customers, including Metro Bank, Betway, and Lottoland, choose to partner with us:

Achieve higher match rates through authoritative multi-source data coverage

A provider may claim coverage across hundreds of markets, but one thing to note is that broad reach doesn’t guarantee strong verification performance. The truth is, matching success depends on data source quality, matching logic, regional expertise, and multi-sourcing capabilities, to name a few. 

For example, when a customer’s records are incomplete, single-source verification could fail –  and force them into step-up checks or manual reviews, slowing down the process.

 

That’s why we combine identity data from multiple authoritative sources across 195+ countries, drawing on hundreds of global and local databases, with access to identity data for 4.4 billion people. We standardize and normalize identity data across providers to maximize accuracy, and by combining traditional and alternative data, boost pass rates by 9%.

The impact of multi-source verification is clear in side-by-side performance tests. For instance, when a financial services company evaluated our identity verification solution – which draws on multiple credit reference agencies – against its incumbent provider, it saw significantly higher UK data-verification match rates. 

Match rates improve further when you look beyond traditional databases. Layering passive signals like mobile, device, and geolocation intelligence helps create a fuller risk picture, and it’s how we’re able to match 300 million consumers using mobile and email data alone. 

This matters most for thin-file applicants: about 35% of traditional verifications fail for Gen Z, whose limited credit and data histories don’t fit standard matching models. Passive signals help reliably verify these users, along with international customers, without driving drop-offs or compromizing on compliance. 

Customize onboarding journeys with flexible workflows and risk rules

Picture a low-risk customer stuck going through the same checks as a high-risk user because your platform can’t tell the difference between the two. Genuine customers abandon the process or your team ends up buried in false positives instead of focusing on users who actually warrant a closer look. 

This is why, while basic plug-and-play platforms work for simple setups, they could become restrictive as compliance obligations and risk models grow more complex.

 

Our GBG Go platform features a no-code, drag-and-drop workflow builder that allows you to design dynamic, risk-adaptive onboarding journeys without engineering support. You can combine more than 110 identity verification and fraud prevention modules to tailor workflows by geography, customer segment, or risk profile.

Low-risk applicants move through sign-up instantly, while secondary checks, such as age validation, affordability assessments, vulnerability indicators or PEP and sanctions screening against 450+ watchlists, are triggered only when risk scores warrant them. 

Beyond building the journeys themselves, GBG Go gives you a performance dashboard with real-time, visual feedback on how your identity and fraud strategy is actually performing. You can see exactly where applicants are dropping off or getting flagged, then make data-driven adjustments to reduce friction and lift pass rates instead of guessing which rule is costing you customers.

This gives you the granular control you need to scale rapidly in regulated sectors like gaming, crypto, fintech and banking.

Detect sophisticated fraud with layered identity verification and advanced fraud signals

Fraudsters now have AI-generated identities, deepfakes and document manipulation tools at their fingertips – and a single verification check won’t catch them. If you’re only checking one signal, whether it’s a document scan or a database match, you’re leaving gaps that sophisticated fraudsters know how to exploit. Closing those gaps requires layering multiple identity and risk signals throughout the onboarding journey.

 

We address this by building multi-layered defense directly into the verification flow. 

Our document verification solution supports more than 8,500 identity document types, including 25+ US state licenses and Digdigitital IDs and executes more than 50 real-time forensic checks with 99% accuracy in detecting photo manipulation. Integrated liveness checks and face matching ensure the applicant is physically present and matches the ID document.

Passive risk signals like SIM-swap detection, email domain scoring and IP geolocation add important context behind the scenes without introducing user friction.

And to stay ahead of emerging threats, our GBG Trust solution analyzes millions of cross-industry identity interactions to spot anomalous behavior, velocity attacks, and multi-accounting in real time. 

How a gaming operator increased its pass rate by 30% with GBG’s identity and address verification solutions

In the crowded online poker market, one operator struggled to balance player due diligence, protection of minors and customer experience while remaining competitive. 

To solve this, they implemented our identity, address and age verification solutions. 

Address verification was the first step, automatically standardizing user data to optimize match rates against authoritative sources like the UK Electoral Roll. Next, age and identity checks were deployed to block underage sign-ups and satisfy strict compliance requirements. Finally, to catch genuine players who fell through the cracks, the client used our multi-source solution to verify customer records against all three of the UK’s credit reference agencies.

This layered approach helped the client increase its new player pass rate by 30% and reduce its player cost-per-acquisition.
