Operational Technology (OT) environments underpin essential services across regulated industries. As infrastructure modernises and remote connectivity expands, exposure to cyber compromise increasingly extends into control systems and distributed operational assets.

We assess OT cyber risk across four critical dimensions to enable accountable risk decisions in safety-critical environments. Exposure to credible threats, including external attack paths, supplier access and sector-specific adversaries.

  • Effectiveness of security controls in preventing, limiting and containing compromise.
  • Integrity of security monitoring and detection to identify malicious activity in a timely and actionable way.
  • Organisational response readiness to coordinate decisions, escalation and recovery under operational pressure.

Operational technology exposure

We help organisations establish an evidence-based view of how OT environments may be accessed or targeted by credible adversaries, aligned to Enhanced Cyber Assessment Framework (CAF) risk identification expectations.

 

 

 

Our services: 

Industrial threat intelligence and adversary analysis: Analysis of sector threat actors and attack patterns targeting operational technology environments.

Benefits of the service to your business
  • Prioritises security investment based on credible risk
  • Improves monitoring against relevant adversary behaviour
  • Strengthens risk discussions with leadership and regulators

External asset and exposure review: Identification and assessment of internet-facing and externally accessible assets connected to OT networks.

Benefits of the service to your business

  • Provides clear visibility of your external attack surface

  • Highlights the exposure points most likely to create risk

  • Supports actions to reduce or remove the exposed risks

Supplier and remote engineering access risk review: Assessment of cyber risks introduced through third-party, vendor and remote engineering access into control systems.

Benefits of the service to your business

  • Strengthens oversight of third-party connectivity across operational systems

  • Reduces cyber risk introduced through supplier and vendor access

  • Improves visibility and governance across your organisation

Operational technology security controls

We evaluate whether OT security architecture, governance and technical safeguards would effectively contain compromise and protect critical operational processes in practice, aligned to recognised frameworks including the Enhanced CAF profile.
 
 
 
 

Our services:

Network segmentation and architecture review: Evaluation of zoning, network segmentation and trust boundaries to determine compromise containment within OT environments.

Benefits of the service to your business

  • Reviews OT network structure, zones and trust boundaries

  • Identifies architecture gaps that could allow compromise to spread

  • Supports stronger segmentation aligned with recognised standards such as IEC 62443

Security controls for remote and distributed OT assets: Review of protective controls securing remote sites, field devices and distributed operational assets.

Benefits of the service to your business

  • Assesses protection across remote OT assets

  • Highlights gaps in visibility and control

  • Builds assurance across distributed infrastructure

OT security testing and penetration testing: Controlled security testing of OT-connected systems to identify exploitable weaknesses in infrastructure and configurations, undertaken proportionately and safely.

Benefits of the service to your business

  • Uncovers exploitable weaknesses in OT systems

  • Validates security controls through practical testing

  • Supports risk-based action on priority issues

Security framework and regulatory maturity assessment: Assessment of governance, risk management and control maturity against recognised OT security frameworks and regulatory expectations.

Benefits of the service to your business

  • Clarifies maturity gaps against recognised frameworks

  • Supports planning for targeted security improvement

  • Helps evidence alignment with regulatory expectations

OT privileged access management: Design, governance and oversight of privileged and remote access controls protecting operational systems.

Benefits of the service to your business

  • Strengthens control over privileged OT access

  • Improves accountability for administrative activity

  • Reduces risk from misuse or compromised accounts

Operational technology visibility

We assess whether malicious activity within OT environments would generate timely and actionable security signals, supporting Enhanced CAF detection in relation to Objective C, particularly C1 security monitoring.

 

 

 

Our services:

OT security monitoring and detection review: Assessment of security monitoring coverage, log sources and alerting configuration across OT environments.

Benefits of the service to your business

  • Identifies gaps in OT monitoring coverage

  • Strengthens detection across operational infrastructure

  • Improves confidence in alerting and visibility

OT attack scenario analysis: Analysis of OT attack scenarios to determine whether existing monitoring and controls would identify and respond to compromise.

Benefits of the service to your business

  • Tests detection against realistic OT threats

  • Highlights gaps in controls and monitoring

  • Supports priority security improvements

Understanding response readiness

We validate whether organisations can coordinate and respond effectively to OT cyber incidents under operational pressure, aligned to Enhanced CAF response in relation to Objective D, particularly D1 response and recovery planning.

 

 

 

Our services:

Operational tabletop exercises: Structured incident simulations to test escalation processes, decision-making and regulatory notification in OT-specific scenarios

Benefits of the service to your business

  • Improves readiness to respond to cyber incidents affecting operational systems

  • Clarifies roles, responsibilities and escalation pathways

  • Strengthens organisational preparedness under real world operational pressure
