Electronic seals for document security.

Secure the authenticity and integrity of your documents.

What is an electronic seal?


An electronic seal, also known as digital seal or eSeal, is the digital equivalent of the classic company rubber stamp.

An electronic seal is based on a digital signature which is associated with a legal entity (organisations or institutions) and used to ensure the proof of the origin, authenticity and integrity of the entity’s documents.

Your digital seal from DeepSign benefits from integration with our own digital identity app DeepID, which makes it easier for your organisation to be verified and enable the seal.

Your electronic seal in accordance with the law.

With DeepSign you can create two types of electronic seals: advanced and qualified or regulated seals.


Advanced seal

An advanced electronic seal is an advanced electronic signature issued by an organisation or an institution. Advanced electronic seals have high evidential value. They are officially recognised by the EU regulation eIDAS, while are not defined in the Swiss Federal law ZertES.


Qualified seal

A qualified or regulated electronic seal is a qualified electronic signature issued by an organisation or an institution. Qualified electronic seals have a very high probative value. They are officially recognised by both Swiss (ZertES) and EU (eIDAS) regulations.
