Universign, Trust Service Provider, at your service!

Before we define the concept of a Trust Service Provider, let’s take a look at the trust services themselves, which are the DNA of our business. 

What is a trust service ?

Trust services are also defined under Article 3 of the eIDAS European regulation. This is an electronic service which consists of: 

  • The creation, verification and approval of electronic signatures, seals and timestamps, and certification relating to these services;  
  • The storage of electronic signatures and seals, or the certification relating to these services.  

Universign, Trust Service Provider

The 2016 eIDAS European regulation created the Trust Service Provider (TSP) status, offering recognised services throughout the Eurozone. It’s also Article 3 of this regulation which defines the concept of a TSP. This is a natural or legal person who supplies one or more trust services, as a qualified or non-qualified Trust Service Provider”. To become a qualified TSP, you must provide qualified trust services and obtain this status from a supervisory body, like the French ANSSI. Universign is an eIDAS European regulation-qualified Trust Service Provider. As such, Universign guarantees fully compliant, secure and fair digital transactions. 

Universign’s role as a Trust Service Provider is also to provide all security guarantees, including legal guarantees, in order to offer electronic signature services that grant evidentiary value to signed documents. 

Assuring a principle of fairness and protecting users’ identities

Universign is a long-standing actor in the trust services market and has always employed the principle of fairness and neutrality in the processing of signatories and clients. 

Furthermore, Universign fully assumes its role as a Trust Service Provider by ensuring the control of data linked to the identity of users. 

Regulatory compliance is at the heart of Universign’s business strategy


Universign is a TSP, qualified in accordance with the eIDAS European regulation which replaces the 1999 European directive on the electronic signature, and its national transpositions. It supports the deployment of a unified regulatory framework at a cross-European level.
