Screening For Critical Infrastructure

Sites that cannot stop, spread across geography, with a constant flow of contractors rather than public visitors. The screening challenge is rarely one gate — it is consistency across many, often where there is no building to put a checkpoint in.

What You're Actually Trying To Stop

Critical national infrastructure screening is usually driven by regulation, insurance or a specific assessed threat, and the population is contractors and staff rather than the public.

  • Weapons and devices at the perimeter — the assessed threat, and the reason the regime exists.
  • Prohibited items and tooling — cameras, phones and equipment entering restricted areas where policy forbids them.
  • Theft of plant and materials — copper, tooling and equipment leaving, which is a screening problem as much as a CCTV one.
  • Inconsistency between sites — the same operator running different regimes at different gates is the vulnerability nobody writes down.

Our recommendation

What We Build For Infrastructure Sites

Rugged, relocatable and consistent — because the estate is rarely one site and never a lobby.

Containerised Checkpoints

A complete screening point built into a container, delivered and craned into position. Screening where no suitable building exists.

Custom solutions →

Perimeter & Distance Screening

Passive terahertz body scanning detects concealed items on people at up to seven metres, screening several at once as they approach.

Body scanners →

Fixed & Portable Detection

Archways, handhelds and rapidly deployable concealed item detection, standardised across sites so every gate runs the same regime.

What You Probably Don't Need

You don't need identical equipment at every gate. You need a consistent standard — which is not the same thing. A main entrance with 400 contractors a morning and a remote substation visited twice a week have different answers, and forcing one specification across both wastes money at one end and creates a queue at the other. What should be identical is the procedure, the training and the maintenance regime. And screening is only worth installing if it will be operated: a gate with no trained operator and no service contract is a capital purchase that quietly becomes scenery.

In practice

How It Runs Day To Day

1

Surveyed site by site

Each gate assessed for flow, power, weather and access, then specified against one consistent standard rather than one identical shopping list.

2

Installed anywhere

Containerised, temporary or permanent, by engineers who are forklift trained and used to sites without loading bays.

3

Maintained nationwide

Multi-brand service across a distributed estate, with parts on the shelf and a hire fleet when a system has to come out.

Any X-ray we supply outside aviation is specified with AI detection as standard — it gives a consistent detection baseline at a gate that may be staffed by a security officer rather than a trained screener. Our engineers work across airports, government estates and secure sites, and hold the vetting that access requires.

Proof

Screening Where There Was No Building

Containerised checkpoints and bespoke builds: when nothing off the shelf fits the problem, we engineer it. Our custom work spans port operations, temporary terminals and permanent infrastructure sites.
