How digital signature certificates work

In terms of eSignatures, European regulation is the most stringent. Third-party providers must comply with norms and obtain a digital signature certificate to offer their service.
Certified providers are subject to frequent audits by independent experts selected by the European Commission.
Selecting a certified provider is imperative to ensure that your signatures will be legally binding and that your agreements and data will be stored securely.
