Overview of OneSpan Sign's esignature workflow

Easy to Use

Provide customers with the most seamless e-signing experience, while keeping the spotlight on your brand

3 Devices Easy To Use

OneSpan Sign is optimized for desktop and mobile signing right ’out of the box’, and enables you to quickly configure the solution for your needs. You can also fully customize the workflows and UX to create a unique customer experience. That includes white-labeling at no extra charge.     

  • Compare a white-labeled signing experience with no white-labeling

    White labeled


    OneSpan Sign’s brand doesn’t appear in any of the interfaces or email notifications.  Your brand remains in the spotlight to ensure the most seamless user experience. This helps drive high adoption and transaction complete rates.

    Not white labeled

    Not White-Labeled

    With some e-signature vendors, their brand is part of the user experience creating confusion and risk of customers dropping off. What’s more, emails are sent from the vendor’s servers, creating the risk of phishing scams,  malware and potential lawsuits as a result.

Notebook - Easy For Dev

Our powerful REST-based open API and SDKs come packed with everything you need to ensure rapid development and deployment. This includes support for common programming languages, including Java, .NET, APEX, Android and iOS, an out of the box UI, sample code, complete documentation, an active developer community, and much more.

Security & Compliance

Prove your compliance and deflect legal disputes with the most comprehensive audit trails

Capture the step-by-step, signing workflow - as seen and experienced by your customers. Our patented ‘visual’ audit trail reproduces all web screens, legal disclosures and documents that were presented, and how long people took at each step. This makes it faster and less costly to prove what happened.

  • Compare Static and Visual Audit Trails

    Static audit trails

    Static Audit Trail

    Captures what was signed

    OneSpan Sign captures standard audit trail information, such as who signed, what document, when (time-stamp), where (IP address), in what order, and how. The static audit trail is embedded directly in the document, making it easier to verify and store e-signed documents as a single, portable file.

    Visual Audit Trail

    Captures all information presented to users during the web transaction

    OneSpan Sign is the only solution to capture active visual audit trail of all information presented to users that helped build their understanding of what there were signing. This includes consenting to OneSpan Sign, all disclosures, and other web screens. This makes it faster, easier and less costly to prove your compliance and build your legal case.

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

Laptop - Error Information

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 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 signatures for each and every signer

    Digital Signature for 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.

    Digital signatures for all

    Digital Signature for ALL Signers

    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.
