Enisa

The EU Cybersecurity Act (CSA) — Regulation (EU) 2019/881 — was adopted by the European Council in April 2019 and fully entered into force on 28 June 2021. It is a European regulation (directly applicable in all Member States without transposition) that serves two primary functions: it strengthened and made permanent the mandate of ENISA (the EU Agency for Cybersecurity), and it established a voluntary EU-wide cybersecurity certification framework for ICT products, services, and processes. The CSA is not itself a certification scheme but rather the legal foundation upon which specific schemes are built — currently EUCC (adopted January 2024), EUCS (cloud, under development), EU5G (5G networks, under development), EUDI Wallets, and EUMSS (managed security services). Each scheme defines assurance levels (basic, substantial, high), evaluation methodologies, and mutual recognition rules so that a certificate issued in one Member State is valid across the entire EU. The CSA applies to any entity — manufacturer, service provider, or operator — that voluntarily seeks EU cybersecurity certification for its offerings, though sector-specific regulations (NIS2, CRA, DORA) may make certification effectively mandatory for certain use cases. A recast of the CSA (CSA2) was proposed by the European Commission on 20 January 2026, aiming to strengthen certification mandates, reinstate sovereignty requirements in cloud certification, and reinforce ENISA’s supervisory role.
