InSign

inSign is an electronic signature platform designed for businesses that want to digitize their document signing processes while maintaining strict data protection standards. The German-made solution supports all three EU signature types: simple electronic signatures for internal approvals, advanced signatures for contracts, and qualified signatures for documents requiring written form.

The platform works like sending an email. You prepare documents, send them to signers, and recipients can sign from any device without creating accounts. Built-in form fields reduce incomplete documents, while audit trails provide legal proof of the signing process. Documents can be signed with typed signatures, handwritten signatures on touchscreens, or qualified certificates.

Key capabilities include: • Multi-language support across 20+ languages • Word and Excel integration for automatic PDF conversion • API access for custom system integration • Template management for recurring document types • Mobile-friendly signing on smartphones and tablets

inSign stands out through its German data sovereignty approach. All servers, data processing, and subcontractors are located in Germany, meaning the US Cloud Act doesn't apply to your data. The platform is ISO 27001 certified and has operated for over 15 years with more than 10 million users across Europe.

The service offers three tiers: inSign 365 as a standalone web application (€90/month per user with 24 signatures included), inSign connect for API integration, and inSign enterprise for comprehensive requirements. All plans include GDPR compliance, eIDAS conformity, and RSA-3072 encryption. Companies report reducing signature turnaround from two weeks to two days while eliminating paper, postage, and printing costs.
