Operational technology

Securing operational technology (OT) requires unique solutions and the knowledge of specialist technicians. The OT environment is sensitive to disruption and often incompatible with standard penetration testing activities. Security must be approached with the expectation that bespoke testing techniques and approaches, specific to your risk appetite, will be required as standard.

Converge operational technology and security to protect your critical operations from widespread disruption and assure human and process safety.

  • Understand your attack surface Uncover actionable information to remediate vulnerabilities in your OT environment.
  • Contextualize your security Build defenses against the tactics, techniques, and procedures (TTPS) used by attackers against OT.
  • Build resilience Strengthen your operational technology architecture through defense-in-depth strategies.
  • Manage and reduce risk Align OT-specific security risks with broader security management practices and IT implementation.

Our approach

Capabilities

Digital transformation, Industrial Internet of Things (IIot) adoption, and increasing global interconnectivity are providing new ways for attackers to target organizations via their operational technology. In response, our OT security team comes with fresh solutions influenced by its direct experience of building, developing, and commissioning operation technology systems.

We’ve worked across regulated and non-regulated industries in the private sector, as well as with public institutions, applying our individual skill sets to help clients achieve their specific desired outcomes. This broad exposure helps us efficiently identify the main areas and systems of focus during assessment and deliver work that adheres to strict safety standards.

OT environments are made up of highly-sensitive systems, often blending modern connected technology with legacy technologies that were not built for today’s level of connectivity. Our consultants ensure that environments are tested and secured to the highest standard without causing operational disruption. Projects are scoped in a bespoke way around the facility or risk area of interest and according to your risk appetite.
