Authonex vs Sumsub

Authonex is an identity verification platform available through the web, an API, or self-hosting. It scans identity documents, screens watch lists, compares faces with ID photos, and issues digital IDs. Document checks cover format, barcode integrity, security features, expiry, revocation, field consistency, and fraud indicators. Digital IDs are cryptographically signed and can be shown as QR codes that refresh every 60 seconds. Zero-knowledge proofs can confirm claims such as age without exposing the underlying personal data. Risk tools include behavioral analysis, device fingerprinting, threat intelligence, real-time scoring, custom rules, and blocklists. The security page describes AES-256 encryption at rest, TLS 1.3 in transit, and hybrid Ed25519 and Falcon-512 signatures. Authonex states it is SOC 2 Type II and ISO 27001 certified and GDPR compliant. Its open-source software is available under the MIT license for customer servers. Cloud verification costs $0.05, paid once. The free allowance is unclear: the homepage lists 100 verifications per month, while developer documentation lists 1,000.

Sumsub is a verification and compliance platform for checking users, businesses, and transactions, detecting fraud, and resolving cases from one dashboard. Its ID Verification supports more than 14,000 document types across 220+ countries and territories, with checks described as completing within 20 seconds. Teams can define verification levels combining documents or selfies, liveness and face matching, questionnaires, payment methods, and other checks. Integration options include a REST API, browser-based WebSDK, and MobileSDK for native iOS and Android. Sandbox and production environments are available, but production API access follows Sumsub’s verification that the integration works as expected. Listed marketplace connections include Okta, Chainalysis, and ComplyAdvantage. A 14-day free trial includes 50 checks, and customers are charged for successful verifications only. Basic starts at $1.35 a month with a $149 minimum monthly commitment; Compliance starts at $1.85 a month with a $299 minimum monthly commitment. Basic and Compliance verification is charged at full cost even if included features go unused. Sumsub was founded in 2015 and is headquartered in London, England.
