Sign large volumes of documents on behalf of your company

Do you need to sign and send documents to a large number of customers (quotas, purchase orders, invoices, standard contracts)?

Automate this process using our eIDAS electronic seals. They guarantee the integrity and origin of your documents and limit fraud attempts.


Addressing companies’ needs for automation and scalability

An electronic seal is the modern, richer equivalent of a company rubber stamp. Companies (in fact all legal entities) apply it manually or automatically to quickly secure massive volumes of documents in just a few minutes:

  • electronic invoices
  • statements, reports, evaluations
  • medical reports and tests
  • software codes or servers

Our expertise at your service

We make sure that your company's digital documents remain protected and compliant over longer periods of time.

Meeting eIDAS strictest requirements, documents secured with a LuxTrust e-seal will gain an irrefutable legal value across EU member states.

LuxTrust is the most recognised player in Luxembourg when it comes to secure authentication. Our IT department works closely with the LuxTrust team for all our applications that require strong authentication. We also use their COSI platform to facilitate the electronic signature and e-sealing of our documents. It was reassuring to implement the e-sealing of digital diplomas using this platform that we already knew well. In addition, we knew that LuxTrust would help us, that they are responsive when required. It was a good choice.
