Qualified Electronic Signatures

When your signing processes require the highest levels of enforceability and trust 

The eIDAS Regulation

E-Signature and Digital Signature Standards Driving Digital Transformation

Regulations like eIDAS in the EU, ZertES in Switzerland, and Medida Provisoria 2.200-2 in Brazil provide broad frameworks, which allow for secure digital authentication and the use of electronic and digital signatures. 

There are generally three forms of e-signature recognized around the world:

  1. Simple E-Signature (SES) 
  2. Advanced E-Signature (AES)   
  3. Qualified E-Signature (QES) 

The Advanced E-Signature is the most commonly used signature type and includes higher identity proofing requirements than the Simple E-Signature. The Qualified E-Signature is an Advanced E-Signature backed by a digital certificate issued by a qualified trust service provider. Stringent identification and digital certificate requirements can make Qualified E-Signatures impractical for many business transactions.
