TS EN 15602

TS EN 15602 is a terminology standard intended to establish a common language for private security service providers and their customers. It helps reduce ambiguity in planning, delivering, procuring, and managing security services by aligning the meaning of key terms used in the sector.

What a terminology standard does

A terminology standard organises the operational vocabulary of a field rather than prescribing a product or a test method. In private security, distinctions between provider, customer, assignment, personnel, premises, and service scope matter in contracts, procedures, training materials, and day-to-day communication. By giving these concepts a shared technical meaning, the standard supports consistent interpretation across organisations and contexts.

Why the distinctions matter in private security

Private security services cover planned activities aimed at protecting people, sites, assets, and processes. General technical context is important here: private security is not the same as public policing, and the service relationship, responsibilities, and boundaries can differ accordingly. A controlled terminology helps organisations describe service scope more precisely, discuss operational roles clearly, and keep documentation consistent when defining tasks, responsibilities, and service interfaces.

This document is based on CEN EN 15602:2022 and focuses on harmonising the terms used in the private security services field. Its value lies in terminology alignment, not in specifying the performance of any particular security system or equipment.
