Add trusted digital signatures and seals to documents

A lot of organizations have created their own electronic document workflows to help transition away from time- and resource-consuming paper processes like onboarding new clients, exchanging contracts, HR tasks, and more.

With Digital Signing Service, companies get an easy-to-deploy and cost-effective way to add digital signatures to these processes, providing higher assurance around signer identity, signature authenticity, and content integrity compared to other types of electronic signatures.

Certifying your documents

Avoid invoice fraud by certifying your documents

Electronic invoicing has gradually become a de facto standard. However, unfortunately, the security level of electronic invoicing remains very poor—paving the way for invoice fraud, which is usually down by changing an account number while in transit.

When you sign your electronic documents using a digital certificate, you protect yourself and your customers against a number of malicious attacks:

If you change as much (or as little) as a comma in a signed document, the recipient will know that the document has been altered. Additionally, he or she will promptly be warned against trusting its content.
