Security Service
The security service oversees all matters relating to security, access authorisation, interactions with other services (Relations with the Host States Service, Protocol Office, Mobility Centre, TSOs, etc.) and supervises contractors’ personnel responsible for security, registration, management of keys and access control.
The service is also responsible for managing all requests for research from authorised persons (legal department, department, relations with host States, internal audit, radiation protection, human resources, etc.).
In addition, the service follows up on all reports of theft or incidents to try to identify the perpetrators, understand the process and put in place human, material or organisational means to prevent their recurrence.
In the same way, the service is involved early on in the design of all new buildings or major renovations in order to define, by means of analysis grids, the security measures adapted to the risks and the purpose of the building.
Finally, the service responds to requests from users for all security-related requests, questions relating to specific problems, or reports of incidents or inappropriate behaviour.
It is also responsible for suggesting improvements to the security system and operational relations with the Swiss and French police forces.Contact

Good practices
Traffic regulations at CERN
The French and Swiss highway code applies on the French and Swiss CERN domain.
The speed limit is 50 km/h. Pedagogical speed radars are deployed in the most accident-prone areas of the domain.
Permanent badge wearing
All persons on the CERN site must wear an access badge or visitor’s card in a visible and permanent place.
Evacuation plan
In the event of a threat, the partial or total evacuation plan of the CERN domain can be activated.
You must follow the instructions given to you without delay.
Unattended luggage
Do not leave your luggage unattended. Abandoned luggage may result in evacuation of the building and may be destroyed without notice. If you discover an abandoned bag, do not touch it and call the CSA at 76666.
Access to CERN
Depending on your status (staff member, contractor, visitor with guarantor, etc…) a registration and a valid access card are required to access the CERN domain.
In accordance with operational Circular No. 2, vehicles, bicycles and pedestrians are controlled to ensure that only authorized persons enter the sites.
Staff members can authorize an external visitor to access the domain by applying for a visitor’s card and vouching for the visitor. Except in exceptional circumstances, the maximum duration of a visitor’s card is 2 days. If the visitor comes to work at CERN under contract, he/she must register as a contractor.
Lost and Found
The Security Service supports the central registration of lost, disappeared or stolen property and is also responsible for the registration, storage and retrieval of found objects.
Any item found on the CERN site must be delivered in person to the CERN guards at Entrance B on the Meyrin site or at the Main Entrance of the Prévessin site.
The declaration of lost personal property might also need a declaration with local swiss or french authorities.
Entrance control and guards
Entrance Control and guards provide essential security-related services to ensure safe access and operations across CERN sites. Their activities include managing access to restricted areas, implementing security and traffic measures, and handling requests related to site use and logistics.
