OT Cyber Security

We offer specialised OT Cyber Security Consultancy to safeguard industrial automation and control systems. Key services include a customisable Cyber Security Gap Assessment (CSGA) to identify risks and ensure compliance with regulatory standards. This supports operational technology cyber security requirements in industrial environments.

We provide an in-depth, five-day OT Cyber Security Training courses focused on practical application of security frameworks and embedding security into system design. This helps cyber security operational technology teams apply good practice in day-to-day work.

Furthermore, we assist in developing strategic approaches to enhance cyber resilience. This includes defining secure system architectures, selecting appropriate security and threat detection solutions, and implementing robust backup and recovery plans to protect critical systems from malware and ransomware attacks as part of a practical OT Cyber Security strategy.

Our OT cyber security services help industrial organisations understand cyber risks, prioritise practical improvements and make informed decisions about protection for operational technology. From OT security consultancy and gap assessments to training, security architecture guidance and recovery planning, MAC Solutions works with businesses to identify appropriate next steps for their sites, systems and operational requirements.

What Does OT Cyber Security Protect?

OT cyber security covers more than malware protection on a single device. In industrial environments, the security strategy needs to protect the systems that control physical processes, the networks that connect them and the people and workflows that keep production running.

Industrial control systems

PLCs, DCS, SCADA, HMIs, RTUs and engineering workstations that control or monitor physical processes.

Networks & remote access

Segmentation, firewalls, secure remote access and controlled connections between plant networks, corporate IT, vendors and cloud services.

Endpoints & legacy systems

Industrial PCs, legacy operating systems and specialist devices cannot always be patched, restarted or replaced on normal IT timescales.

Removable media & contractors

USB devices, portable media and third-party maintenance workflows can introduce malware or unauthorised files into isolated OT environments.

Backup, recovery & version control

Validated backups, configuration history and recovery plans help restore known-good OT systems after failure, ransomware or unauthorised change.

Risk, governance & compliance

Assessments, policies and security architecture can support frameworks and obligations such as IEC 62443, the NCSC CAF and applicable NIS requirements.

Why OT Cyber Security Needs a Different Approach

OT environments have different priorities from conventional IT. Production availability, safety, deterministic processes and long asset lifecycles mean security controls have to be introduced without creating new operational risk.

A standard office endpoint can often be patched, restarted or replaced quickly. A production HMI, engineering workstation or control-system server may depend on validated software, vendor support and planned shutdown windows.

A practical OT security programme therefore combines asset understanding, network segmentation, controlled access, removable-media protection, backup and version management, threat detection and tested recovery.

Key OT security considerations

• Availability and safety need to be protected alongside confidentiality.

• Legacy and vendor-managed systems may not support frequent patching.

• Industrial protocols and devices can expose different attack surfaces.

• Third-party and maintenance access must remain practical but controlled.

• Security changes should be tested around production and safety requirements.

How Our OT Cyber Security Consultancy Works

A structured OT security engagement should reflect the systems, operational constraints and priorities of each site. The following outlines a practical approach to discussing and planning services with MAC Solutions:

Understand the environment. Discuss critical assets, existing controls, operating requirements and the main areas of concern.
Assess and prioritise. Where appropriate, explore a Cyber Security Gap Assessment to identify security gaps and develop prioritised recommendations.
Plan the response. Consider security architecture, suitable protective technologies, staff training and backup or recovery requirements.
Agree next steps. Define the appropriate consultancy, training or solution requirements, including any further scoping needed before implementation.
