CERN is committed to maintaining a secure environment for its personnel, site and assets. In line with this commitment, the Director-General has adopted the CERN Security Policy in order to set out the framework for the physical protection of CERN personnel and any other contributors on the CERN site, of the CERN site itself and of the property and assets in the Organization’s custody.

The Security Policy aims to prevent, avoid or mitigate risks against the Organization while preserving the campus spirit.

CERN contributors are expected to familiarise themselves with this Policy and with their responsibility to contribute to a secure working environment. A dedicated online course “Security Awareness / Sensibilisation à la sûreté” is available on the CERN Learning Hub.

To support the implementation of this Policy, the Director-General appointed a Security Committee in October 2024. This Committee has been established to advise the Director-General on security matters, to recommend updates to the Security Policy and measures and to monitor its implementation. It consists of the Head of the department in charge of security (SCE) acting as Chair, the Head of the Security Service, and one representative from each of the following: the Human Resources department, the Legal Service, the Occupational Health and Safety and Environmental Protection unit, and the Host State Relations service.

We appreciate your cooperation in fostering a secure and protected environment at CERN. For further information, please contact the Security service.
