Visibility that drives OT maturity
OT security auditing is specialized work. Your environment has specific needs that generic compliance frameworks don't always address. A thorough audit provides visibility into your assets, identifies vulnerabilities specific to your operations, and prioritizes improvements that matter for your environment.
-
Complete visibility into your OT asset base. You know exactly what you have, where exposures are, and what to prioritize first.
-
Confidence in your IT/OT segmentation. Trust that your security is working as intended, with gaps identified and addressed before they become entry points.
-
Security controls tested against reality. Your controls hold up against real-world attack scenarios.
-
Compliance that fits your organization. Regulatory requirements are practical, right-sized, and built around how you operate.
-
Security model that scales with you. Clear roles, shared accountability, and governance that grows as your organization grows.

Gain a complete understanding of your security across your entire site. We assess how your organization manages security, your architecture and policies, infrastructure controls, and physical security, providing you with a clear picture of where your OT security currently sits.
OT Penetration Testing
OT controls are tested against real attack scenarios in a controlled, safe way. This allows you to understand which vulnerabilities pose actual risk and how they could be exploited.
IT/OT DMZ Penetration Testing
Network boundaries are tested to ensure your IT/OT segmentation protects your operations. This is meant to identify any gaps before attackers do.
Targeted audits
A focused assessment looks at areas that matter most to your environment. Whether it's network architecture, physical security, configuration, or organizational maturity, you get a deep understanding of the areas that need it.
Security compliance advisory service
Receive practical guidance grounded in real-world experience, not just theory. Understand which regulations and standards actually apply to your operations and how to meet them in ways that work for you.
Benefits of OT security auditing
Auditing services deliver outcomes that strengthen your business:
-
Identify and prioritize vulnerabilities. Risk is addressed before it becomes an incident.
-
Contain threats with strong network segmentation. They're stopped before spreading across your environment.
-
Validate detection and response against real threats. Controls work in practice, not just theory.
-
Strengthen resilience without disruption. Security improvements don't slow down or shut down your operations.

OT Security Auditing FAQs
What is an OT security audit?
An Operational Technology (OT) security audit assesses the cybersecurity posture of industrial systems, networks, processes and supporting infrastructure. It is designed to identify vulnerabilities, security gaps and areas of risk across OT environments while taking into account operational availability, safety and continuity requirements.
Why is OT security auditing important?
OT environments often contain legacy systems, specialist equipment and critical processes that were not originally designed with modern cyber threats in mind. An OT security audit helps organizations understand where weaknesses exist, assess whether controls are effective and prioritize improvements that strengthen operational resilience.
What does an OT security audit include?
The scope depends on the environment and objectives of the assessment, but an OT security audit may review network architecture, segmentation, system configurations, security controls, policies, governance, remote access, asset visibility, physical security and relevant operational processes.
How is an OT security audit different from an IT security audit?
An IT security audit focuses primarily on enterprise systems, applications, users and data. An OT security audit considers industrial systems and operational processes where availability, safety and production continuity are critical. Testing methods and recommendations must therefore reflect the specific constraints of operational environments.
What is the difference between an OT security audit and OT penetration testing?
An OT security audit provides a broader assessment of security posture, including architecture, policies, governance, controls and technical weaknesses. OT penetration testing is more focused on identifying and validating exploitable vulnerabilities through controlled testing. The two approaches can be complementary.
Can OT security testing disrupt industrial systems?
OT environments can be sensitive to traditional security testing techniques, so assessments must be carefully scoped and planned. Integrity360 tailors testing to the operational environment and works with relevant stakeholders to minimize unnecessary disruption while still providing meaningful security insight.
What is IT/OT network segmentation?
IT/OT network segmentation separates enterprise IT systems from operational technology environments using appropriate security controls and network architecture. Effective segmentation can help reduce the risk of attackers moving from compromised corporate systems into critical operational networks.
What is IEC 62443?
IEC 62443 is a series of international standards focused on cybersecurity for industrial automation and control systems. It provides guidance for organizations, system integrators and product suppliers on managing cyber risk and implementing appropriate security controls across industrial environments.
What is NIST SP 800-82?
NIST SP 800-82 provides cybersecurity guidance for Operational Technology environments, including industrial control systems, building automation and other operational systems. It covers areas such as risk management, network architecture, access control and security monitoring while recognizing the specific operational requirements of OT.
How often should an OT security audit be conducted?
OT security audits should be conducted regularly and following significant changes to systems, architecture, processes or risk exposure. The appropriate frequency will depend on the organization, sector, regulatory requirements and criticality of the environment, but periodic reassessment helps ensure that new exposures are identified and addressed.
What types of OT environments can be assessed?
OT security audits can be applied across a wide range of industrial and operational environments, including manufacturing, energy, utilities, transport, maritime, critical infrastructure and other environments that rely on industrial control systems and operational technologies.
Can an OT security audit identify risks in legacy systems?
Yes. Legacy systems are common in OT environments and may have outdated operating systems, unsupported software, weak authentication or limited security functionality. An audit can identify these risks and recommend compensating controls or other practical measures where immediate replacement is not possible.
What happens after an OT security audit?
Following the assessment, Integrity360 provides findings and prioritized recommendations based on the risks identified. These can help organizations address vulnerabilities, strengthen controls, improve segmentation and develop a practical roadmap for improving OT cybersecurity over time.
Can Integrity360 assess compliance with OT security standards?
Yes. Integrity360 can assess OT security controls and processes against relevant regulations, recognized frameworks and industry standards depending on the organization's requirements. This may include IEC 62443, NIST SP 800-82 and other applicable security or regulatory guidance.
