Adobe Acrobat is a tool: Adobe Acrobat implements the technical mechanism to sign any document by any user. However, the electronic certificate used in the process is self generated by the computer. In other words, you can trust that signed document as long as you trust the person and the computer who has given it to you. This is normally ok for internal documents with low risk implied. Anyone in Solvay can use this tool under his/her own responsibility about the content and the usage of the tool. DocuSign is a Trust Service Provider under EU legislation: DocuSign (as many other similar services in Internet) implements the same mechanism as Adobe Acrobat, but it also generates and maintain the electronic certificates used during the signature. By using these publicly trusted electronic certificates, contracts signed via DocuSign are automatically accepted as a valid proof in case of trial or disputes. In fact, when you use Adobe Acrobat for viewing a PDF signed by DocuSign, it automatically checks in the background with DocuSign if all the signatures and certificates are valid and trustworthy. You can only use DocuSign to sign documents if your signature represents Solvay company. In a nutshell: Both tools allows you to sign a PDF, however the only one that can be automatically accepted as contractual for agreements between Solvay and other companies is via DocuSign |
