Case Study: DocuSign achieves secure, reliable eSignature processing with iText

How DocuSign uses iText in their eSignature electronic signature solution

DocuSign, a pioneering developer of electronic signature technology, faced the challenge of processing a wide variety of PDF documents for its eSignature platform. Many of these PDFs had structural irregularities or were non-compliant with ISO standards, which posed a risk to the reliability and security of their digital signing service. To provide a comprehensive and resilient solution for its customers, DocuSign needed to ensure its platform could handle these malformed documents without error.

iText provided a key component of the solution by being integrated into DocuSign's backend as one of the PDF toolkits used for processing. This created multiple levels of redundancy, allowing the service to automatically fall back to iText to resolve document issues, ensuring a high availability and reliable customer experience. As a result, DocuSign's eSignature platform delivers secure, PKI-based digital signatures that comply with global standards. The vendor iText also provided world-class support, leading to a collaborative relationship where DocuSign even contributed code back to the iText open-source library.
