OneSpan Sign vs VeriDoc Sign

Enterprise-grade security and new blockchain storage, but seat pricing and no QR—see where OneSpan shines and where it falls short.OneSpan Sign has decades of PKI heritage and is trusted by banks and insurance giants. In 2023 it introduced a “quantum-safe blockchain storage” option that records signature evidence on a proprietary ledger—but the signed PDF itself still carries no QR code or embedded hash; auditors must open a portal to cross-check documents.Pricing starts at $25 per user per month with 100 envelopes per user per year. Bulk send, SSO, high-volume API calls and advanced branding require the Enterprise tier (custom quote). Seat licences stack quickly: a 25-user compliance team on Enterprise often exceeds $1,000 monthly before overages.Security certifications are strong (FIPS 140-2, SOC 2, ISO 27001, FedRAMP Moderate). OneSpan also offers biometric and hardware-token authentication unmatched by most rivals. Yet authenticity still relies on OneSpan’s custody of the evidence vault, and unused envelopes expire annually—budget friction for seasonal workflows. Teams that require immutable, self-contained proof or flat costs across departments often find VeriDoc Sign’s QR-plus-blockchain model and single-price plan more predictable.
