Signzy vs Onfido Review: Which Identity Platform Wins in 2025?

We get asked about Onfido a lot. Makes sense, they’re a well-known player in identity verification, and if you’re evaluating solutions, you’ve probably got us both on your shortlist.

Here’s the thing: we respect what Onfido has built. They’ve done a solid job establishing themselves in the market, especially in Europe and North America. But when we were building Signzy, we made some different choices about how identity verification should work, choices that we think matter a lot in practice.

This isn’t a hit piece on Onfido. They’re a legitimate option for many use cases. But if you’re comparing us, you should understand where we’re genuinely different, not just where our marketing messages diverge. First, let’s take a quick glance at the Signzy vs Onfido comparison.

Signzy vs Onfido: Quick Glance

Signzy vs Onfido for Document Support: What’s Better?

The Verdict: Onfido wins on raw numbers, but Signzy delivers superior regional expertise where it matters most.

Document Type Support

Onfido supports over 2,500 document types across 195 countries, which is genuinely impressive. Signzy covers 200+ ID types from 180+ countries. Fewer on paper, but here’s what the numbers don’t tell you.

Onfido’s approach is breadth-first: they’ve catalogued thousands of document variations, including historical versions and regional variants. 

Signzy’s approach is depth-first: we focus on the documents that actually matter for modern digital businesses, with deep expertise in how they’re used in practice. Our OCR handles 50+ languages with understanding of document layouts and validation rules, not just text extraction.

Language & Script Support

Both platforms handle multiple languages, but there’s a crucial difference in implementation. Signzy’s OCR, apart from reading text, understands document layouts, spots forgeries, validates expiry dates, and auto-classifies formats.

Onfido covers more script variations, but Signzy’s focus on practical business languages means better accuracy where it counts. When you’re processing thousands of Indian Aadhaar cards or Southeast Asian national IDs, depth of understanding beats breadth of coverage.

Signzy vs Onfido for API & Developer Experience: What’s Better?

The Verdict: Signzy takes the lead with superior flexibility and developer-friendly implementation.

API Marketplace Advantage

Signzy offers 340+ API microservices for validation & verification of both individuals and businesses, while our US API marketplace provides comprehensive KYC, KYB, AML, and fraud prevention solutions. Onfido provides a solid API suite, but it’s primarily focused on identity verification.

The difference is architectural philosophy. Onfido built an identity verification API. Signzy built a comprehensive verification ecosystem where identity is just one component.

Developer Resources

Both platforms provide comprehensive documentation, but Signzy’s approach to developer support is more hands-on. We have a dedicated team of support professionals who are available 24/7 to assist you with any queries or issues, including product training sessions and webinars to help you better understand and utilize our products and services.

Customization Capabilities

Signzy’s platform enables millions of customers daily with the capability to handle a million queries every day. More importantly, customers can manage their own data, privacy, security, storage and retrieval with complete control over their data.

Onfido’s no-code Studio is powerful for standard workflows, but Signzy’s architecture allows for deeper customization without requiring engineering resources.

Signzy vs Onfido for Fraud Detection: What’s Better?

The Verdict: Onfido has a slight edge in AI maturity, but Signzy’s practical approach delivers comparable real-world results.

AI Technology Comparison

Onfido’s Atlas AI is built on over 10,000 micromodels that decipher the slightest nuances of global ID documents, refined on tens of millions of verifications. 95% of checks are processed in less than 10 seconds, a 12x improvement, with year-over-year improvement in fraud accuracy by 54%.

Signzy’s AI takes a different approach entirely. Our Fraudulent Behaviour Detection (FBD) pulls data from social media, news sources, court records, and business registries to build comprehensive risk profiles. When someone applies for verification, we’re analyzing their digital footprint across multiple databases simultaneously to catch fraud that document-only systems miss.

Fraud Detection Approaches

Onfido excels at catching document-level fraud through advanced biometric analysis and synthetic document detection. Their specialized fraud research team continuously develops new techniques to stay ahead of evolving document forgery methods.

Signzy approaches fraud from a business intelligence angle. While we catch document fraud effectively, our strength is identifying suspicious patterns that emerge when you connect identity verification with credit behavior and entity relationships, fraud signals that single-point verification often misses.

Practical Performance

In real-world deployments, both platforms deliver strong fraud detection. The difference is in edge cases and regional variations. Signzy’s fraud detection adapts to new geographies, documents, and risk without requiring model retraining.

Liveness Detection & Deepfake Prevention

Onfido Motion uses iBeta PAD Level 2 compliant liveness technology, protecting against sophisticated digital spoofs, display attacks, and 2D and 3D masks with anti-spoofing performance that’s 10-times more accurate than before.

Signzy’s deepfake detection and liveness checks verify real users in seconds with accurate identity screening. While Onfido’s technical specifications are more detailed, Signzy’s practical implementation delivers comparable protection against spoofing attacks.

Signzy vs Onfido for Cost Effectiveness: What’s Better?

The Verdict: Signzy delivers significantly better value at every business scale.

Pricing Model Comparison

Industry sources suggest the median annual spend for Onfido customers is approximately $60,475, with costs ranging from $6,156 to $945,900 per year depending on the verification volume and scope of services required. 

Users believe that Onfido is only worth it for companies with a high user volume, whereas businesses with fewer users may find it less appealing, with substantial upfront cost that can be a significant financial burden for SMEs or startups.

Signzy’s pricing is accessible for growing businesses while remaining competitive at enterprise scale. We serve 10+ Fortune 30 companies, proving that cost efficiency doesn’t mean compromising on enterprise-grade capabilities.

Total Cost of Ownership

Beyond per-check pricing, consider implementation and maintenance costs. Onfido’s complex pricing model varies based on several factors, including the scale and complexity of your verification needs, making budget planning difficult.

Signzy’s integrated approach means you’re not paying multiple vendors for different verification needs. Our APIs cover everything from KYC and KYB to credit checks, AML screening, and bank account verification.

When Should You Choose Signzy Over Onfido?

In most scenarios, Signzy offers superior value and better alignment with modern business needs. Here are the key situations where Signzy is the clear winner:

• You’re Building a Fintech or Financial Services Product

Signzy provides comprehensive financial verification including bank account verification, credit underwriting, and AML transaction monitoring – capabilities that Onfido simply doesn’t offer. If you need more than just identity verification, Signzy eliminates the need for multiple vendors.

• Budget and Cost Efficiency Matter to Your Business

For growing companies, Signzy’s value proposition is compelling. You get enterprise-grade verification capabilities without enterprise-grade pricing complexity. Our 340+ seamless plug and play API solutions coupled with our global no-code AI platform can digitize your enterprise at any scale.

• Your Want Global Coverage

This is where Signzy’s regional expertise becomes invaluable. While Onfido covers these markets on paper, Signzy understands the practical challenges of verification in emerging markets and has built solutions that actually work reliably.

• You Want a Platform That Grows Beyond Identity Verification

Signzy offers KYC, KYB, and AML APIs with capabilities for digital contracting and AI-first AML transaction monitoring. As your business evolves, Signzy grows with you instead of requiring additional vendor relationships. Our One Touch KYC product has been recognized by Gartner for innovation in streamlined verification processes.

The Two Scenarios Where Onfido Might Make Sense

To be fair, there are specific situations where Onfido could be the better choice:

• You Need Maximum Document Type Coverage Above All Else

If your specific use case requires verifying obscure historical document variants or you process documents from literally every country including rare regional variations, Onfido’s 2,500+ document support might be worth the premium.

• You’re Already Locked into the Entrust Ecosystem

Since Onfido was acquired by Entrust in 2024, if you’re already heavily invested in Entrust’s broader security infrastructure, the integration benefits might outweigh other considerations.

However, for the vast majority of businesses, from growing startups to Fortune 30 enterprises, Signzy delivers superior value, faster implementation, and better long-term strategic alignment with Gartner-recognized innovation.
