Document Signing Overview 

As more business is conducted online, digital document signing plays an ever increasing role in authenticating and verifying the integrity of documents and files used in legal, financial, real estate, and other transactions. The convenience, safety, and nonrepudiation of digital signatures is unparalleled. 

This is only possible if cryptographic keys used in document signing are secure and can’t be stolen, lost, or compromised. Unfortunately, they are often stored in the clear and are easy to access or misplace. The consequences can be dire.


As both cyber and physical security attacks increase, the Engage BlackVault Hardware Security Module (HSM) provides best practices document signing security by ensuring only authorized signatures are created and keys are kept safe.
