Code Signing for VBA and Macros

Show that your Visual Basic Applications & macros are from a trusted developer. Digitally Sign Microsoft Office Macros and Visual Basic Applications (VBA)


GlobalSign Code Signing Certificates for Macros and VBA are used to digitally sign VBA objects, scripts, and macros within Microsoft Office.

When end users open documents containing unsigned macros, they receive security alerts advising them "not to enable content unless they trust the source of the file". Digitally signing your macro binds your identity to the code and displays your name within the file, alleviating the end user's concern about running code from an unknown source. Any changes to the macro made after the signature has been applied, such as insertion of a virus, will invalidate the signature, protecting your name and reputation.

Why Sign Code?

Add an essential level of trust to the application installation process.
The solution is simple – Sign your code!

Unsigned macros are automatically disabled in most Microsoft Office programs. End users are warned that macros may contain security hazards and to only enable content if they trust the source of the file.

Once digitally signed, end users can clearly see the name of the publisher and that the signature is valid. If they trust the source, they can change their settings to automatically enable all macros from that publisher in the future.
