Confidencial Sign

Because unlike other e-signature tools, we never access or store your data or use sensitive customer documents to train our AI models.


Your documents and agreements remain exclusively within your existing infrastructure 100% of the time, where they belong.

The Confidencial CoSign e-signature solution is easy to use

Why does the world need another e-signature solution?


Ditch the risk.

E-signatures have become a cornerstone of efficiency for organizations and their clients, streamlining the cumbersome processes of document exchange, completion, and signing. Still, the security vulnerabilities inherent to most e-signature SaaS solutions remain a critical oversight. Traditional e-signature service providers often rely on cloud storage for the sensitive documents exchanged and signed electronically, inadvertently opening the door to two things:

These services could use customer documents to train federated large language models.


A significant increase in data exposure risk, given that 80% of data breaches involve cloud-stored data.
