ETSI EN 303 645 — IoT Security
Demonstrate that your consumer IoT device meets the European baseline cybersecurity standard with our expert assessment and testing services.
What Is ETSI EN 303 645?
ETSI EN 303 645 is the European baseline cybersecurity standard for consumer IoT devices. Published by the European Telecommunications Standards Institute (ETSI), it provides 13 provisions covering fundamental security practices that every consumer IoT product should implement.
The standard is referenced by the Radio Equipment Directive and is expected to serve as a key harmonised standard under the Cyber Resilience Act for default-category consumer IoT products.
The 13 Provisions
- No universal default passwords — unique per device or user-defined during setup
- Implement a vulnerability disclosure policy — public point of contact and timely acknowledgement
- Keep software updated — secure, timely updates with clear information to users
- Securely store credentials and security-sensitive data
- Communicate securely — use encryption and authentication for network communications
- Minimise exposed attack surfaces — disable unused services and ports
- Ensure software integrity — verify updates and detect unauthorised changes
- Ensure personal data is secure — appropriate protection of user data
- Make systems resilient to outages — graceful degradation and recovery
- Examine system telemetry data — security logging and monitoring
- Make it easy for users to delete personal data
- Make installation and maintenance of devices easy — clear guidance
- Validate input data — protect against malformed or malicious input
