OT Security Maturity Assessment

Evaluate the cybersecurity posture of your Operational Technology (OT) and Industrial Control Systems (ICS) environments. Identify gaps between IT and OT security practices, and build a roadmap to protect the systems that control physical processes.

Overview

Operational Technology environments — SCADA systems, PLCs, DCS platforms, HMIs, and industrial networks — increasingly converge with corporate IT infrastructure. This convergence introduces cyber risks to systems that were historically isolated, often running legacy software with limited patching and no native security controls.

Our OT Security Maturity Assessment evaluates your organisation's ability to detect, prevent, and respond to cyber threats targeting industrial and operational environments. We benchmark your OT security posture against recognised frameworks such as IEC 62443, NIST SP 800-82, and the SANS ICS security model to provide a clear maturity score and an actionable improvement roadmap.

Who This Is For

  • Manufacturing companies with connected production lines and SCADA systems
  • Energy, oil & gas, and utilities organisations with critical infrastructure
  • Pharmaceutical and chemical facilities with process control systems
  • Building automation and smart facility operators
  • Any organisation with OT/ICS environments seeking a security baseline

What We Assess

  • OT network architecture, segmentation, and DMZ design
  • IT/OT convergence points and boundary controls
  • Asset inventory completeness and visibility into OT devices
  • Patch management and vulnerability management for OT assets
  • Remote access mechanisms to OT environments
  • Monitoring, detection, and logging capabilities within the OT network
  • Incident response readiness specific to OT scenarios
  • Vendor and third-party access governance
  • Physical security controls and their integration with cyber controls
  • Personnel training and OT security awareness

What You Receive

  • OT Security Maturity scorecard benchmarked against IEC 62443 / NIST 800-82
  • Detailed gap analysis across all assessment domains
  • Risk-prioritised remediation roadmap with quick wins and strategic initiatives
  • IT/OT convergence risk assessment
  • Executive summary suitable for board-level reporting
  • OT-specific incident response playbook recommendations
