For years, government agencies, banks, and healthcare providers have relied on external platforms to capture signatures, forcing sensitive data to leave secure environments. E-Sign+ changes this architecture by binding signatures directly to submission data within the user's self-hosted technology stack. This approach ensures that information remains under local control, satisfying stringent regulatory requirements that previously made standard digital signature vendors unviable.

The system provides cryptographic verification, meaning any subsequent alteration to signed data automatically invalidates the signature, maintaining an unbroken chain of custody. This is particularly relevant as organizations move toward AI-driven workflows where data integrity is paramount. According to COO Heather Hornor, the solution allows entities with the most rigorous security mandates to modernize their document workflows without compromising ownership of their APIs or cryptographic keys.

By consolidating infrastructure, companies can eliminate the complexity of managing separate vendor relationships and disconnected document processes. While the tool still supports the generation of signed PDFs, it functions independently of document-based dependencies. E-Sign+ is available immediately as a licensed add-on for existing Form.io enterprise deployments.
