In recent times, eSignatures have become a new normal and are being used in almost all countries across the globe. However, in certain countries, not all eSignature types are the same. Amongst these, a digital certificate-based signature is a type of eSignature which carries more evidentiary value in a court of law validated by Certifying Authorities. Attaching a digital signature certificate (DSC) is necessary to authenticate the signer’s identity and enable tamper-proofing. These Digital Certificates are issued by a Trust Service Provider, commonly known as TSP.  

You don’t want to form a business agreement, fully execute it, and deliver it, only to learn later that you lack the legal authority to enforce it in the event of a dispute. This is why when making these agreements, you should always use electronic Trust Service Providers (TSPs), which operate under EU regulations for id verification. 

However, for your peace of mind, using a qualified trust service provider (QTSP) should be involved for the highest level of security. 

What is a Qualified Trust Service Provider? 

A TSP becomes a Qualified TSP or a QTSP for that country if it is approved by the national supervisory body to offer one or more qualified trust services. Qualified eSignatures, or QES, are eSignatures that are carried out using digital certificates obtained from QTSPs. Advanced eSignatures, or AES, are used when digital certificates are obtained from TSPs not authorized to offer qualified trust services. TSPs mainly offer digital certificates via USB tokens, Smart Card, Cloud Signature, and National ID. 

What is a qualified trust service provider

Difference between TSP and QTSP 

A trust service provider may provide electronic signatures, electronic seals, timestamps, registered delivery services, certificates for website authentication, and other services. They can offer a single service or a number of them. Trust services come in two types: general and qualified. The qualified version of the services, which can be referred to as a form of “insurance,” can only be provided by QTSP. 

A QTSP is the only type that can provide qualified trust services, which is one of the key differences between a TSP and a QTSP. A QTSP frequently offers both qualified and unqualified trust services. The reversed burden of evidence in any disputes—where it will be up to the QTSP alone to demonstrate the accuracy of the benefits—typically results in higher costs for qualified services. The consumer will then determine whether you require the added value that the qualified services offer.  

A QTSP must go through an independent audit by an accredited institution (i.e., one acknowledged by the national accreditation body) to comply with the EU eIDAS law. This audit looks at things like security, degree of trust, and quality. In other words, QTSP is a high-standard quality stamp. These rules are designed to increase consumer and business trust and to encourage the use of reputable trust services.

It frequently occurs due to compliance: the requirement to follow eIDAS, PSD2, or related legislation. No matter where your company is headquartered, you are obligated to follow European laws if you conduct business within the EU. 

But many additional factors could influence a company’s decision to cooperate with a QTSP in implementing certified certifications. 

  • Trusted Proof and Reduced Liability
    In court, qualified trust services may be used as evidence. Unless shown otherwise, Qualified Trust Services are taken to be utterly reliable evidence. Contrary to how electronic evidence is typically handled, where it is frequently necessary to establish the accuracy of electronic records or procedures before using them.
  • Trust and Assurance
    The highest level of confidence and trust now offered on the market is provided by qualified services. This additional layer of protection is essential for day-to-day operations, particularly in sectors where confidence is paramount, such as the banking sector, education, or utilities.
  • Visual symbols of EU trust
    Businesses that utilize QTSPs can include an EU trust mark on their websites and other materials, giving them a competitive edge and fostering more customer trust.
  • Global Compliance
    The legal requirements for signatures and legal transactions might occasionally differ significantly across various nations. Therefore, an electronic signature must comply with the regulations in each nation if you conduct business across multiple countries, such as in Europe. Often, all that is needed is an advanced electronic signature. However, there are stringent requirements that electronic signatures be qualified if you want to conduct business in Belgium, for instance, and many nations are going toward this paradigm. If you choose a QTSP, you will be free to decide whether to utilize qualified or advanced electronic signatures. Whichever type of signatures you select (AES or QES), QTSP will offer the most effective service as it is identified by trusted certificate authorities  The person executing the signing procedure must still be trusted, and requiring a QTSP would make it simple to accomplish this. A QTSP can also deliver advance signatures, but you can trust that a reputable entity is carrying out the procedure of verifying signatures in that case.


Any business can be certain that an electronic transaction is completely safe by using a Qualified Trust Service Provider.
With a Qualified Trust Service provider your enterprise can: 

  • Reduce the risk of your electronic transactions significantly 
  • Identity Authentication
