Legally Binding

Legally compliant with U.S. and international laws

BoldSign is legally compliant with U.S. (ESIGN) 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.

Enterprise-grade data security
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.
