Everything Your Team Needs for Efficient E-Signing

Bulk eSignatures Requests Made Easy

Allows you to send the same eSignature requests to multiple recipients with one click. Each recipient receives their unique copy to sign, ensuring that the process is quick, error-free, and scalable.

Secure Identity Verification

Ensures the signer’s identity through secure methods like government ID proof and biometric face verification, providing enhanced protection for sensitive agreements. This verification process helps businesses meet regulatory standards, prevent fraud, and ensure compliance.

Brand Your Signature Requests

With extensive branding customization options, you can create a fully branded signing experience. Customizing logos, colors, and email templates ensures that every interaction with recipients reflects your company’s identity, offering a more professional and cohesive signing experience.

Track in Real Time

Tracking signature requests gives you real-time updates on the status of your documents from sending to completion. It allows for full visibility in the signing process, providing notifications at each stage and ensuring that no document goes unsigned without notice.

Share Links and Collect Signatures

Embed signature URLs on your website or send secure URLs via email to multiple signers. This is perfect for getting documents like account applications, event registrations, and NDAs signed. No coding required: a user-friendly interface. A great alternative to Docusign’s PowerForms. Start collecting signatures quickly!

Text Signature Requests

The ability to send signature requests via SMS provides a more immediate and accessible option than email. Recipients can quickly receive, review, and sign documents on their mobile devices, making it particularly useful for high-engagement or time-sensitive agreements.

Legally compliant with U.S. and international laws

BoldSign is legally compliant with U.S. (ESIGN, UETA) and international (eIDAS) eSignature laws. We record all major activities that happen during the signing process and provide a downloadable copy of the complete audit trail report. The final document is also digitally signed so that any tampering in the future can be immediately detected.

Your data is protected using bank-grade security standards

We take data security very seriously and have built it into every aspect of the application right from the beginning. All the data stored and transmitted is encrypted using 256-bit AES encryption standards. Your data is completely secure to the point where our own staff do not have access to it even for troubleshooting purposes.

Certified with SOC 2®, GDPR, HIPAA, and PCI DSS compliant

As a company committed to providing secure and trustworthy services to our clients, we are proud to announce that Syncfusion’s BoldSign is certified with SOC 2®, GDPR, HIPAA, and PCI DSS compliant. This means that we have implemented strict security measures and data protection protocols to ensure the privacy, confidentiality, and integrity of our clients’ data.
