On-Premises or SaaS...

On-Premises is an installation on your own server. You are responsible for the operation yourself. You have unlimited control over your system and the use of inSign. Updates and maintenance work are your responsibility.
With SaaS, inSign is responsible for the operation. The application runs on a cloud on a server in a German data centre of a German company. Of course, the e-signature software is maintained and regularly updated by us.
