An air-gapped OT network is intended to have no direct connection to other networks or the internet. A connected OT network has one or more links to business systems, suppliers, remote access platforms, cloud services or other external environments. In practi

Enhance your OT network security with regular testing: conduct periodic risk assessments, quarterly vulnerability scans, annual penetration testing, and ongoing configuration reviews. Don't wait for an attack to reveal weaknesses—strengthen defences with continuous monitoring and improvements. OT network security should be tested regularly, but testing must be planned carefully. Unlike corporate IT systems, OT systems may be sensitive to intrusive scanning, unexpected traffic

The importance of ICS cybersecurity is highlighted with a focus on protecting critical systems across various sectors, including manufacturing, energy, oil and gas, transportation, and government, emphasizing the shared responsibility in safeguarding against cyber threats. ICS cyber security is the protection of industrial control systems. These systems monitor and control physical processes in environments such as manufacturing, energy, water, chemicals, utilities, transport

Implementing Zero Trust in Industrial Settings: A Modern Security Strategy for Operational Technology. Zero trust is often summarised as “never trust, always verify”. In an industrial environment, this does not mean blocking operations or adding friction to every process. It means reducing implicit trust, verifying access, limiting privileges and monitoring important activity. OT environments need a careful version of zero trust. Controls must not interfere with safety, avail

Overview of key compliance standards for OT systems, including IEC 62443 for industrial automation security, NIS2 for cyber resilience, UKCA for UK-specific frameworks, ISO/IEC 27001 for information management, and OG86 for oil and gas cybersecurity guidance. The standards and regulatory expectations that apply to OT systems depend on your sector, location, role in essential services and customer requirements. Common references include IEC 62443, the NCSC Cyber Assessment Fra

Ransomware Threats in Manufacturing: Understanding the Impact on Operations and the Need for Resilience. Ransomware is often associated with corporate IT systems, but its impact on manufacturing can be operational. If business systems, engineering workstations, file shares, domain services, scheduling tools or quality systems are unavailable, production may slow down or stop. In some incidents, organisations shut down production as a precaution because they cannot confirm whe

Enhancing SCADA Security: A professional monitors critical infrastructure systems to detect threats, secure operations, and ensure safety and reliability. SCADA stands for Supervisory Control and Data Acquisition. SCADA systems help operators monitor and control industrial processes, often across plants, utilities, pipelines, energy sites, manufacturing lines and infrastructure networks. SCADA security is the protection of these systems from cyber threats, misuse and failure.

Enhancing Cybersecurity for Legacy Industrial Equipment: Optimize Safety with Network Segmentation, Access Control, Threat Detection, and Virtual Patching Without Replacement. Yes, cyber security can often be improved around legacy industrial equipment without replacing everything. Many OT environments contain systems that are too critical, expensive or specialised to replace quickly. The key is to reduce exposure and manage risk in a way that respects operational constraints

Exploring Essential OT Cybersecurity Certifications: Build a capable team with credentials in ISA/IEC 62443, CISSP, GIAC, ISO/IEC 27001, and CompTIA Security+ for enhanced expertise, credibility, and confidence. Certifications can help OT teams build consistent knowledge, but they are not a substitute for practical industrial experience. The best OT cyber security capability combines cyber security knowledge, engineering understanding, safety awareness and familiarity with st

Protect Your Operational Technology: Assess, Identify, and Strengthen Defenses Against Risks with Comprehensive OT Monitoring. Your operational technology may be at risk if you cannot clearly answer basic questions about assets, connectivity, access and recovery. OT risk is not always visible from day-to-day operations. Systems may appear stable while containing weaknesses that only become obvious during an incident. Warning signs include incomplete asset inventories, unknown
