EU cybersecurity standards are at risk if supplier ban passes

Help Net Security

The European Telecommunications Standards Institute (ETSI) has submitted a position paper to the European Commission regarding the proposed Cybersecurity Act 2 (CSA2). The paper raises concerns about two key provisions: expanding the European Union Agency for Cybersecurity's (ENISA) role in setting technical standards and a proposed ban on entities from countries deemed to pose cybersecurity risks from participating in European standardization efforts. This ban could impact the development of cybersecurity standards in the EU, potentially limiting collaboration and innovation. The ETSI argues that such restrictions could hinder the overall effectiveness of European cybersecurity measures, affecting businesses and consumers alike. The outcome of this proposal will be significant for the future of cybersecurity in Europe.
