Our Trust Triangle

Our services form an integrated ecosystem of signature, identity and legitimation tools that together redefine signing and expression of will on the web.

Electronic Signature

The electronic signature makes digital signing in a legally and secure manner possible. It is thus a core element of digitisation and enables the conclusion of any type of contract. No printing, no sending of letters, no scanning – everything is completely digital with an electronic signature.

See Signing Service
Legally compliant

Legitimate for qualified signatures according to EU regulation eIDAS and Swiss federal law ZertES.


Pan-European signature solution with a simple interface for integration into an existing application.


During the signature there is no access to document contents, as only “hashes”, are transmitted.


Electronic identification (eID) is a secure way of identifying a person online. Secure online identification allows many new business opportunities in the web: e.g. for government authorities, in eHealth, for concluding digital contracts in combination with an electronic signature or for opening a bank account.

See Smart Registration Service

With a one-time identification, people can sign electronically multiple times over several years.


Depending on the jurisdiction or signature, you can select the right ID method for your process.


All ID-methods are compliant with the EU regulation eIDAS and the Swiss federal law ZertES.


Wherever you need to digitally conclude important transactions, maximum security and usability are always required. The most secure 2-factor authentications (e.g. Mobile ID) on the market offer both and, as a digital key, enable a secure electronic declaration of intent.

See Authentication Methods

Secure two-factor authentication combines physical and digital protection for the electronic expression of will for signature.


The authentication methods work on all mobile phones.

Legally compliant

All authentication methods are approved for electronic signatures in the EU and Switzerland.
