Critical National Infrastructure

Plextek addresses the needs of customers wishing to safeguard CNI and high-risk buildings against a variety of security threats.

The protection of your security sites & high value infrastructure – physical installations such as prisons, power stations, utilities, oil refineries, hotels, palaces, electricity networks – represents Plextek’s primary mission.

A key focus is on countering UAVs and protecting against other forms of illegal and restricted area trespass, including solutions for rapid alerting and tracking in the case of unauthorised person and vehicle movements.

Typical solutions for effectively resolving threats of the above nature include specialised radar product development coupled with integration of pan tilt and zoom cameras. You also benefit from complete solutions that include user friendly Human Machine Interface(s) for effective command & control as well as a variety of sensors, e.g., radar, thermal & visual cameras etc.

In an era where the safety and security of national infrastructure and high-risk buildings are strict, our commitment to protecting these assets against diverse security threats has never been more important. From the busy corridors of oil refineries to the critical networks of electricity provision, this is our priority.

We specialise in technologies for countering uncrewed aerial vehicles (UAVs) and preventing trespass in restricted areas, offering rapid alert and tracking solutions for unauthorised personnel and vehicle movements.

Our approach combines advanced radar technology with integrated surveillance systems—including pan-tilt-zoom (PTZ) cameras and user-friendly human-machine interfaces—for full command and control. Our clients benefit from tailored, effective solutions designed to safeguard their most valuable assets.

Keeping vital systems and networks safe is what we do at Plextek. We deliver tailored solutions for unprecedented security challenges, ensuring the robust protection of critical infrastructures is at the core of our mission.
