After 2 years of active use, I can recommend a-trust.at for Qualified Electronic Signatures (QES) connected to your EU identity. I am a German passport holder. But, unfortunately, all QES Services are so expensive and user-hostile in Germany that I decided to use an #Austrian service for this. The a-trust app and website are well designed and signing PDFs worked always flawlessly. They are also pretty transparent about data use. They are listed as a certified provider by the #BSI [1].
Having documents signed by QES is a great help in many digital processes today, as it provides proof that they were signed at a specific time and have not been modified since.
