What you will find in the Certyneo blog

The Certyneo blog publishes practical analyses on electronic signature every week for HR, legal, commercial and financial teams. We break down eIDAS regulation and its application in France, compare leading market solutions (DocuSign, Yousign, Adobe Sign), share anonymized experience reports by sector (law firms, real estate agencies, accounting firms), and publish step-by-step guides for migrating or complying with GDPR. All articles cite their regulatory and technical sources and are reviewed by our legal team before publication.

How do you verify the legal information published?

Each article touching on the legal value of signature, eIDAS regulation, GDPR or a sectoral obligation is reviewed by our legal team before publication and cites its sources: Official Journal of the European Union, French Civil Code, CNIL opinions, CJEU decisions, and ANSSI texts where applicable.
