The DocuSign Security Appliance is a software application that enables you to store and manage DocuSign eSignature encryption keys within your data center—in the application or in your Hardware Security Module (HSM). It is a premium add-on for DocuSign eSignature, utilizing the same core data encryption technology as DocuSign’s ISO 27001-certified encryption systems, and delivering the same easy-to-use eSignature experience. Customers can design their security and maintenance processes around the appliance and are responsible for appliance maintenance and updates.
