}'OneSpan Sign vs Signbee: Military-Grade Security vs Developer-Grade Simplicity
OneSpan Sign is the e-signature platform of choice for financial institutions, government agencies, and healthcare organisations that require the absolute highest level of document security. Its AES 256-bit encryption, embedded cryptographic audit trails, and identity verification with liveness detection represent the gold standard in high-stakes signing. The question is whether your use case requires that gold standard.
Embedded vs External Audit Trails
OneSpan's defining feature is embedding the cryptographic audit trail directly into the signed document. If someone alters a document between signers, prior signatures are visibly invalidated. This is powerful for sequential multi-party signing in regulated industries. Signbee takes a simpler approach: a SHA-256 signing certificate attached to each document provides tamper-proof verification. For two-party signing (the vast majority of developer use cases), this is equally legally binding.
Identity Verification
OneSpan offers FIDO hardware authentication and facial liveness detection. These are essential for high-value financial transactions and government documents. For a SaaS developer sending NDAs, freelancer contracts, or employee offer letters, hardware authentication is unnecessary friction. Signbee verifies identity through email-based OTP — sufficient for standard commercial signing.
Pricing Complexity
OneSpan's pricing is modular: base subscription ($22+/user/month), SMS authentication ($0.10-$0.50 per verification), bulk send fees, and API integration fees are all separate line items. The total cost of ownership becomes unpredictable at scale. Signbee's pricing is flat and transparent — you know exactly what you'll pay before you send a single document.
Notarisation
OneSpan offers In-person Electronic Notarisation (IPEN) and Remote Online Notarisation (RON) — features Signbee does not provide. If your workflow requires notarised documents, OneSpan is one of the few platforms that handles this natively.
