A Hardware Security Modules (HSM) is a physical computing device that safeguards and manages digital keys for strong authentication and provides crypto processing. These modules traditionally come in the form of a plug-in card or an external device that attaches directly to a computer or network server.

Note: HSM requires a special type of signature certificate known as Class 3 Signature and Encryption certificate. This is different from DSC.

Generally, organization need to migrate on HSM based signing due to several factors. Organization having thousands of documents to sign on daily basis should move in the direction of HSM based document signing.

If an organization is using the HSM, then the certificate and keys would be stored in it and not on any DSC token. When the PDF document signing software needs to sign a PDF document, it would retrieve the certificate and keys from the HSM and will complete the signing operation.
