TÜV Informationstechnik GmbH Certificate is a proof of compliance with eIDAS Regulation in terms of trust services provided.
Since 2002, Certum has been included in a list of Certification Authorities (CA) since 2002 and periodically undergoes compliance audits for the trust services it provides:
- Qualified electronic signature

Certum, as the first Polish entity, was included in the exclusive list of trusted issuers of certificates – Adobe Approved Trust List (AATL).
Every electronic signature issued by Certum is automatically recognized and displayed as valid in PDF documents opened in the Adobe software. Thanks to this, the recipients of such documents worldwide get a clear signal in the form of a prompt at the top of the window, which informs them that the signature they see is compliant with the highest standards of quality and security.
