INDUSTRIES

Critical Infrastructure

Protecting critical infrastructure with secure technology designed to improve visibility, resilience and operational continuity across cyber, OT, IoT and physical environments.

ABout The Industry

Protecting the systems society depends on.

Critical infrastructure organisations operate systems where disruption can have significant operational and societal consequences. Increasing connectivity between IT, OT, IoT, communications and physical infrastructure creates new opportunities but also new risks. CDS helps organisations understand their exposure and strengthen resilience across increasingly connected environments.

The Challenge

Resilience where disruption isn't an option.

Critical infrastructure teams must protect essential services while meeting regulatory expectations and managing threats across increasingly connected digital and physical environments.

Regulatory Requirements

Security teams must demonstrate appropriate resilience against obligations including the NIS Regulations and Cyber Assessment Framework (CAF).

OT & IoT Exposure

Connected operational technology and IoT devices create new routes into systems that support essential functions.

OT & IoT Exposure

Connected operational technology and IoT devices create new routes into systems that support essential functions.

Physical & RF Threats

Threats can extend beyond networks to physical sites, wireless systems and the radio-frequency environment.

Specialist Expertise

Specialist expertise, where it matters.

CDS brings together specialist services across cyber, intelligence, data, engineering and technology to address the requirements of each operating environment.

Industry in Focus

Resilience across connected infrastructure.

Critical infrastructure increasingly depends on the interaction between digital systems, operational technology, communications and physical assets. Alongside cyber and regulatory requirements, organisations need to understand threats across the physical and RF environment. CDS brings together cyber security, information assurance, systems engineering and specialist RF capabilities to help identify exposure and strengthen resilience.

Our Approach

Building resilience across the whole environment.

CDS helps organisations identify exposure, monitor their environment and understand threats across cyber, OT, IoT and RF domains.

Assess

Map systems and operational exposure.

Monitor

Identify changes and potential threats.

Analyse

Understand risk and potential impact.

Protect

Strengthen resilience and response.

Real-World Applications

Protecting what keeps operations moving.

CDS supports infrastructure organisations in improving visibility, reducing exposure and strengthening resilience.

Threat Monitoring

Identify suspicious activity across connected environments.

Infrastructure Security

Protect systems that underpin essential operations.

RF & Spectrum Monitoring

Detect unusual or unauthorised activity around critical sites.

Operational Resilience

Reduce the potential impact of security incidents and disruption.

Example Application

Identifying exposure across connected operations.

A critical infrastructure operator may rely on legacy equipment, modern IT systems, connected OT and wireless technologies. CDS can help map the environment, identify areas of exposure and monitor cyber and RF activity to improve visibility and strengthen resilience without compromising operational continuity.
