Digitally Sign Microsoft® Office Documents

Prove document origin, add approval signatures, and prevent tampering.

GlobalSign's PersonalSign Digital Certificates allow you to digitally sign Microsoft Office documents. A digital signature is the virtual equivalent of a wet ink signature, carrying the signer's identity and assuring the reader of the document's integrity.

Placing a digital signature on a document proves the information originated with the signer and has not been altered, allowing secure electronic document workflows to replace tedious, paper-based processes.

Office Digital Signatures for the Enterprise

Implementing secure Microsoft Office document signing across an organisation is easy with EnterprisePKI (ePKI) for managing multiple PersonalSign Certificates for document signing. ePKI offers significant cost savings over purchasing individual PersonalSign Certificates, along with simplified deployment options and robust reporting features. All organisation information and certificate history is stored within one centralised account so administrators can issue, renew, resissue, and revoke PersonalSign Certificates on demand.
