Security and Compliance

Prove your compliance and deflect legal disputes with our audit trail

Audit trail

Captures identity verification, authentication, and e-signature events of the entire agreement process and signing experience in a single, unified audit trail.  Our audit trail provides a more complete picture of the transaction with strong identity assurance to demonstrate compliance for remote processes.

Secure your documents and each person’s signature using military-grade, digital signature technology

OneSpan Sign guarantees document integrity by applying a digital signature and tamper seal after each person has signed, and then automatically detecting if a change is made to the digital document in between signers. And unlike other providers, OneSpan Sign embeds the audit trail directly in the document, enabling you to instantly verify it with just one click.

Compare OneSpan Sign's Security with the Competition

Digital Signature after EACH & EVERY Signer

OneSpan Sign secures each person’s signature in the document using digital signature technology so that if a change is made in between signers, their signature is visibly invalidated. This deters fraud and provides a more reliable audit trail. The audit trail is directly embedded in the document, resulting in a single file that’s easier to verify and manage.


Some other e-signature solutions only apply a tamper seal wrapper at the end of the signing process, enabling the document’s content to be modified without detection in between signers. What’s more, their audit trail is only available as a separate file, forcing you to store two files and making it longer to verify.

Built on leading infrastructure services from Amazon, IBM and Microsoft to ensure high application security

Security compliance

Keep your company and customer data safe using Advanced Encryption Standard (AES) 256-bit encryption. OneSpan Sign complies with SOC 2 Type II, HIPAA, FedRAMP and other stringent industry security and privacy requirements. See the summary of the auditor’s report at the Trust Center.
