Understanding the Complexity of OT Environments
OT environments are inherently heterogeneous, making oversight and security more complex. Operational technology environments can be complex, presenting multiple challenges that require careful attention:
We work with manufacturing, utilities, and critical-infrastructure organisations across Auckland, Northland, and New Zealand, where legacy OT systems often predate modern security controls and require a careful, non-disruptive assessment approach.
- OT networks often include diverse legacy systems, proprietary technologies, and interconnected devices.
- Limited visibility into OT networks and devices makes it difficult to fully understand the attack surface and potential vulnerabilities.
- Many industrial systems were not designed with security in mind, and retrofitting protections can be challenging.
- Aligning IT and OT teams, bridging knowledge gaps, and coordinating approaches can be difficult.
Understanding your constantly evolving cybersecurity landscape is essential
- Assess your current security posture
- Identify and understand operational risks
- Receive actionable recommendations across people, processes, and technology
- Achieve and maintain regulatory compliance
- Support and justify informed investment decisions
Assessment Tiers
OT Security Assessment [Basic]
- We work with you to define your business and security requirements and engage with your key experts.
- We assess your overall OT security posture.
- We review your OT network architecture and design.
- We deliver a comprehensive assessment report detailing findings, insights, and tailored recommendations.
OT Security Assessment [Advanced]
- We collect comprehensive information through interviews and document reviews with your designated experts.
- We conduct site walkdowns, gathering representative samples for detailed analysis.
- We perform tool-based identification of assets and network communications.
- We deliver a thorough assessment report, including a complete inventory of assets, identified vulnerabilities, and actionable recommendations across people, processes, and technology.
OT Security Assessment [Design]
- We review your OT network architecture through a security-focused lens.
- We design a secure network architecture tailored to your OT environment.
- We translate our security recommendations into practical measures and solutions for implementation.
- We conduct a comprehensive assessment to strengthen your defenses against potential threats.
- We perform risk analysis and prioritise strategic actions to enhance IT/OT separation and overall OT network security.
- We provide a detailed evaluation of your current OT security posture.
OT Security Assessment Questions
OT assessments prioritise safety and availability over aggressive exploitation, since operational technology often controls physical processes. We use non-disruptive testing techniques suited to industrial environments.
We work primarily with manufacturing, utilities, and critical-infrastructure organisations across Auckland, Northland, and New Zealand, including sites with legacy SCADA and industrial control systems.
No. Our assessment tiers are designed to be non-disruptive to live OT environments, using passive network analysis and carefully scoped active testing where appropriate.
It depends on your current visibility into your OT environment and your compliance needs. Get in touch and we'll recommend the right starting point based on your systems and objectives.
