Origin & development of inSign


As a result of an internal research project of iS2, the product inSign emerged in 2011.


inSign was awarded the Service Innovation Prize by Service-Rating GmbH.


Initially, signatures could be placed synchronously during a conversation, for example. Since 2014, asynchronous processing and signing by participants has also been possible.


In 2015, the electronic signature solution received many additional functionalities, such as the choice between signing via app or web browser.


For a long time, inSign was only available as an enterprise solution for large companies and corporations. Since 2018, the cloud solution “inSign smart business” for small and medium-sized enterprises, as well as self-employed persons and freelancers is also available.


In 2020, the product variant “inSign smart business” was renamed to “inSign 365” in connection with an online shop. Furthermore, a new product variant “inSign connect” was launched, which enables easy integration into existing systems.
In the same year, inSign received the BITMI certification “Software Made and hosted in Germany”. Likewise, in 2020 iS2 AG as a whole went through the information security certification “VdS 10000”.


The certificate-based qualified signature according to eIDAS is now also directly available. The desired signature type can be specified separately for each signature field.
