ETSI EN 303 645

Published by the European Telecommunications Standards Institute (ETSI), ETSI EN 303 645 is an IoT cybersecurity specification designed to secure IoT hardware and block potential cyberattacks and data breaches. It defines baseline security requirements for connected IoT devices, covering device authentication, data encryption, software upgrade and vulnerability management. Its core objective is to bolster IoT device security and mitigate risks to personal privacy and corporate data. This standard mandates robust authentication controls, reliable communication encryption, and timely security patch mechanisms to lower the risk of device compromise. Additionally, it requires hardware manufacturers to adopt security-by-design throughout R&D and provide clear, transparent privacy disclosures for end users. The standard delivers clear actionable guidelines for manufacturers and developers, helping build IoT products compliant with European cybersecurity rules and supporting the secure evolution of the global IoT ecosystem.
