Digital Signing Service

With Digital Signing Service, you get high-volume, cloud-based digital Signing-as-a-Service without the need to manage any hardware or build custom integrations.

The demand for trusted and legal digital signatures has never been greater. Our Digital Signing Service powered by GlobalSign makes it easy to add digital signatures and seals to existing document workflows and applications.

Digital Signing Service is API- and cloud-based, allowing organizations to benefit from long-lived, trusted digital signing, content integrity, and trusted timestamps without the need to manage any hardware or build complex, custom integrations.

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.

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:

When you certify your electronic documents using a digital certificate, you protect yourself and your customers against a number of malicious attacks — including invoice fraud, which often occurs when changing an account number in transit.

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

Digital signatures for Adobe Sign or DocuSign users

Digital signatures are available for companies of all sizes via a seamless integration between Digital Signing Service, Adobe Sign, and DocuSign:

The cloud-based integration provides a true end-to-end signing experience and lowers barriers such as cost, hardware maintenance, and internal expertise.

Digital Signing Service handles all the cryptographic components needed to deploy digital signatures: signing certificates, time-stamping, key management, OCSP, and CRL services.
All this is performed behind the scenes, which means that no development time, hardware investment, or advanced PKI knowledge is required.
