Purpose-built security assessments for operational technology environments including SCADA, ICS, DCS, and PLCs. We protect critical infrastructure from cyber-physical threats that disrupt production, compromise safety, or cause environmental harm, with IEC 62443 aligned reporting.
Purpose-built assessment covering your control systems, network architecture, protocols, and safety integration.
Evaluate supervisory control and data acquisition systems, HMI interfaces, and industrial control systems for vulnerabilities without disrupting live operations.
Review programmable logic controllers and remote terminal units for insecure ladder logic, hardcoded credentials, and unauthorised firmware modification risks.
Assess human-machine interface stations, engineering workstations, and operator terminals for weak OS configurations, unpatched software, and RDP exposure.
Audit historian servers, data collectors, and reporting systems for insecure protocols, weak authentication, and data integrity risks.
Evaluate engineering workstations used for PLC programming and configuration for unauthorised access, malware risks, and IT-OT crossover vulnerabilities.
Assess the interaction between security controls and safety instrumented systems to ensure cyber response never compromises physical safety.
Analyse your OT network architecture against the Purdue Model, identifying gaps in segmentation, flat networks, and unauthorised IT-OT crossover paths.
Analyse Modbus, DNP3, OPC DA/UA, BACnet, and PROFINET traffic for cleartext transmission, spoofing, and replay vulnerabilities.
Identify unauthorised network paths between IT and OT zones, assess firewall rules, and validate that demilitarised zones enforce proper isolation.
Test wireless access points, VPN gateways, and remote access pathways into OT zones for authentication weaknesses and unauthorised entry.
Review firewall rules, DMZ configurations, and access control lists between OT zones for overly permissive rules and misconfigurations.
Monitor network traffic passively to map communication patterns, identify undocumented connections, and detect anomalous device behaviour.
Audit authentication mechanisms, role-based access controls, and remote access pathways into OT zones for privilege escalation risks.
Identify default passwords, shared accounts, and inactive credentials with privileged access to OT systems and management interfaces.
Develop OT-specific incident response playbooks that integrate with safety instrumented systems and respect operational constraints.
Evaluate patch management processes for OT systems, including risk-based patch prioritisation and testing procedures that minimise operational impact.
Review SIEM integration, log collection, and alerting configurations to determine whether your team would detect a real OT-focused attacker.
Map security controls and findings to IEC 62443, NIST CSF, NERC CIP, and sector-specific regulatory requirements for audit readiness.
A structured six-phase process aligned with IEC 62443 and NIST CSF, from asset inventory through a phased remediation roadmap.
Map all OT assets, data flows, and network topology validated against the Purdue Model for segmentation gaps and undocumented connections.
Identify threat vectors specific to your industrial environment including IT-OT crossover, remote access, supply chain, and insider threats.
Passive and active scanning of OT assets using purpose-built tools that will not impact process availability or safety systems.
Analyse industrial protocol traffic including Modbus, DNP3, OPC UA, and PROFINET for cleartext transmission, spoofing, and replay vulnerabilities.
Test access controls, patch management, logging, backup integrity, and remote access security against IEC 62443 requirements and your operational constraints.
Deliver prioritised findings with risk ratings, IEC 62443 mapping, and a phased remediation roadmap that respects operational constraints and production schedules.
Factories, refineries, and processing facilities running SCADA, PLC, and DCS systems where a cyber incident can halt production and compromise safety.
Power generation, water treatment, and utility companies operating critical infrastructure that must maintain continuous availability and meet regulatory compliance.
Railway, maritime, and logistics operators with OT-dependent signalling, routing, and control systems where cyber attacks create public safety risks.
