Feature Comparison
LuxSign
Sovereign Luxembourg Data Hosting
LuxSign's foundational and most critical feature is its exclusive data residency within Luxembourg. Unlike platforms that use global or US-based cloud servers, LuxSign ensures all document processing, encryption, and storage occurs on secure servers physically located in Luxembourg. 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. This feature removes the legal ambiguity often associated with digital signatures, offering a secure and court-admissible audit trail. For transactions requiring higher assurance, the platform is structured to support Advanced and Qualified Electronic Signatures, making it a versatile legal tool.
Intelligent Drag-and-Drop Workflow Builder
Streamline complex signing processes with an intuitive visual editor. Users can effortlessly drag and drop signature, initial, date, and text fields onto any PDF or Office document. This feature allows for the configuration of parallel signing (all signers at once) or sequential signing (in a specific order), enabling the automation of multi-party agreements, HR onboarding, or client contracts with just a few clicks, dramatically reducing processing time from days to minutes.
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. It centralizes control, enhances visibility into team activity, and simplifies the management of high-volume signing operations, making it ideal for legal, sales, and HR departments that handle numerous contracts simultaneously.
