Qualified Electronic Signature · eIDAS

Digital signature at institutional scale.

A qualified signature is not a PDF with an image on top. It is a legal act with full evidentiary value, equivalent to a handwritten signature.

Sigillex manages the complete lifecycle: identification, certificate, OTP signature, archiving. From the browser. No installation required.
