Feature Comparison

LuxSign

Luxembourg-Based Security & Compliance

LuxSign's architecture is built on the principle of data sovereignty. All documents are encrypted during transmission and storage using industry-standard encryption, and are hosted exclusively on secure servers within Luxembourg. This ensures full compliance with the EU's General Data Protection Regulation (GDPR) and Luxembourg's stringent data protection laws, providing unparalleled peace of mind for handling sensitive business and personal data.

eIDAS-Compliant Electronic Signatures

The platform provides Simple Electronic Signatures (SES) that are fully compliant with EU Regulation 910/2014 (eIDAS).

Flexible Signing Workflows

LuxSign empowers users to design efficient signing processes. You can add multiple signers to a document and choose between parallel signing (all sign at once) or sequential signing (in a defined order). This flexibility, combined with drag-and-drop signature field placement, allows for the automation of complex approval chains, saving significant time over manual routing.

Comprehensive Audit Trail & Management

Every action taken on a document is meticulously logged in a tamper-proof audit trail. This includes detailed timestamps, IP addresses, and signer information for each view and signature. This feature is essential for compliance verification, internal record-keeping, and providing indisputable proof of the signing process should any questions arise.
