This guarantees compliance with GDPR and the strict Luxembourg data protection legal framework, providing unparalleled peace of mind for businesses handling sensitive European personal and corporate data. Your documents never leave the protective jurisdiction of the EU.
eIDAS-Compliant Legal Validity
LuxSign is built to comply with the EU's eIDAS regulation (910/2014), providing Simple Electronic Signatures (SES) that are legally admissible and valid for a vast majority of business transactions across all 27 EU member states.

Comprehensive Collaboration Workspaces
Move beyond single document transactions with dedicated team workspaces. This advanced feature allows teams to organize documents into folders, manage member access permissions, and collaborate seamlessly on ongoing signing projects.
