Overview

SIST EN 17483-4:2026 sets sector-specific requirements for the provision of private security services in the energy sector. Developed by the Slovenski inštitut za standardizacijo (SIST) and aligned with European Standard EN 17483-4, this document supplements the general standards defined in EN 17483-1 with requirements tailored to the unique operational and risk landscape of energy infrastructure. It aims to define quality criteria for security organization, processes, personnel, and management, supporting both public and private clients in selecting and evaluating private security service providers for the energy sector.

This standard is part of a broader framework for the protection of critical infrastructure and is intended to enhance resilience, operational continuity, and security for entities responsible for vital energy services, excluding nuclear power plants.

Introduction
The objective of this document is to set minimum criteria for the provision of energy sector security
services as part of both national and international critical infrastructure.
This document is built on EN 17483-1, which covers the basic and common requirements for all sectors
of critical infrastructure, which meets the need to aim for high quality and harmonized quality criteria
for private security services providers. This, in turn, contributes to good functioning of society. In
outlining what makes a private security company a worthy provider of such crucial critical infrastructure
as the energy sector, the document aims to contribute to the professionalisation of clients and providers
of private security services.
The series of documents, building on EN 17483-1, which establishes the basic requirements, and all
further upcoming sector specific documents of the EN 17483 series (including this document) follows a
transparent structure as shown below (see Figure 1).

Figure 1 — Structure for sector-specific standards
The final goal is to create the necessary sector specific documents for every suitable and applicable sector
within critical infrastructure according to the outlined sectors as of EN 17483-1:2021, Annex A.
These sector-specific standards are necessary to compensate for the lack of, or gaps in, legislation. They
are meant to help certifiers check the compliance with the provisions of the main requirements standards
and the sector-specific ones.
This document incorporates the broad interdisciplinary expertise of various organisations and
individuals involved in standardization and private security services at both national and international
level.
This document is not limited solely to the protection of critical infrastructures in the energy sector;
rather, it adopts a broader and more strategic security approach. Its objective is to ensure the protection
and operational continuity of these infrastructures and the assets owned or managed by critical entities
responsible for providing essential services.
These essential services are directly related to the sectors and subsectors specified in the annex of
Directive (EU) 2022/2557 [1] of the European Parliament and the Council of 14 December 2022 on the
resilience of critical entities. Furthermore, their non-exhaustive list has been approved by the European
Commission through Delegated Regulation (EU) 2023/2450 [2] of 25 July 2023, supplementing Directive
(EU) 2022/2557.
1 Scope
This document gives the sector specific requirements for the provision of private security services in the
energy sector that are additional to the requirements of EN 17483-1.
This document specifies service requirements for quality in organization, processes, personnel and
management of a security service provider and/or its independent branches and establishments under
commercial law and trade as a provider with regard to security services in the energy sector.
This document defines quality criteria for the delivery of security services in the energy sector requested
by public and private clients. This document is suitable for the selection, attribution, awarding and
reviewing of the most suitable provider of security services in the energy sector.
NOTE 1 This document is the Part 4 of a series of standards on the provision of private security services for
critical infrastructure. See Figure 2.

Figure 2 — Structure for sector-specific standards
NOTE 2 It is important that the selection of a private security service provider always represents the best balance
between quality and price. This document sets out the minimum requirements that providers are expected to
comply with in order for this balance to be struck.
This document is not applicable to private security services in nuclear power plants.
