Perimeter security levels

Choose the protection level to match the site’s risk

The protection needs of critical infrastructure are assessed site by site. Explore the three perimeter security levels and their typical solutions.

1 Low risk level

Basic site protection

Industry, warehouses and logistics centres. Chain-link fence, automated sliding gates and boom barriers.

See perimeter security level 1

2 Critical risk level

Reinforced protection

Sites within the scope of the CER Directive that require resistance to forced entry and climbing. Panel fence and reinforced gates.

See perimeter security level 2

3 High risk level

Certified maximum protection

358 High Security fence, LPS 1175 certified Betafence products and crash-tested gates for the most demanding sites.

Key considerations

Typical requirements

The CER Directive obliges critical infrastructure operators to document their physical security measures. LPS 1175 classifies fences and gates according to their forced entry delay time.

A typical site requires a two-layer perimeter. The outer fence prevents unauthorised approach, and the inner perimeter can only be entered in a controlled way. Gates are integrated with surveillance and alarm systems.

The delivery includes all necessary documentation, certificates and commissioning records. We work closely with the security manager and the auditors.

Frequently asked questions

Critical infrastructure

What does the CER Directive require of the physical protection of critical infrastructure?

The CER Directive (EU 2022/2557) and the Finnish CER Act 310/2025 oblige critical entities to carry out a risk assessment and draw up a resilience plan. The plan describes technical and security measures, including the physical protection of premises and the infrastructure located on them. Perimeter security is one of the key parts of implementation.

Which sectors are covered by the definition of critical infrastructure?

The CER Act covers 11 sectors, namely energy, water supply, waste water, transport, digital infrastructure, health, banking, financial market infrastructure, public administration, food and space. Most water, energy and telecommunications sites fall within the scope of the Act, and their perimeter security requirements are assessed entity by entity.

What kind of fence suits a power plant or a water treatment plant?

A typical choice is a 2D panel fence (8/6/8) at medium-risk sites and a 358 High Security fence or an LPS 1175 certified Betafence Securifor fence at high-risk sites. The fence is combined with automated sliding gates and speed bi-folding gates whose response matches the response times of guarding and the authorities.

Can Pur-ait provide documentation for regulatory audits?

Yes. Pur-ait supplies certificates (LPS 1175, ASTM F2781), product specifications, installation reports and service agreement documentation as part of the delivery. The material is designed to support audits by the supervisory authorities (including the Finnish Energy Authority, Traficom and the National Emergency Supply Agency).
