The European Commission endorsed the joint toolbox of mitigating measures agreed by EU Member States to address security risks related to the rollout of 5G, the fifth-generation of mobile networks. This follows the European Council's call for a concerted approach to the security of 5G and the ensuing Commission Recommendation of March 2019. Member States have since identified risks and vulnerabilities at national level and published a joint EU risk assessment. Through the toolbox, the Member States are committing to move forward in a joint manner based on an objective assessment of identified risks and proportionate mitigating measures. With its Communication adopted, the Commission is launching relevant actions within its competence and is calling for key measures to be put in place by 30 April 2020.
