Our USPs - what do we do better than others?
Our company is 100% German also with servers in Germany. We comply with high standards of data protection and legal compliance; these are topics we treat with the highest sensitivity.
inSign has already been on the market for 10 years and is Germany's market leader in many sectors.
After the first signatory has signed, changing the document is no longer possible, i.e. all contractual partners sign the same version of the document.
All employees of iS2 AG (producer of the software solution inSign) are bound to secrecy according to § 203 StGB. This also applies to all subcontractors used.
inSign supports all signature types according to eIDAS. These are the simple (SES), advanced (AES) and qualified electronic signatures (QES). The required signature type can be specified for each signature field.
The process creator specifies the expected signatures including their positions thereby preventing signatories from signing in the wrong place. Furthermore, PDF documents can be filled with various form fields.
