OT Cybersecurity Assessments

In today’s industrial landscape, Operational Technology (OT) systems face increasing cyber threats. A robust cybersecurity assessment is a critical first step in protecting industrial control systems and critical infrastructure. At Danguard, we offer comprehensive OT cybersecurity assessments that identify vulnerabilities, evaluate your security maturity, and guide you toward stronger compliance and risk management. Our services include Gap Assessments, Risk Assessments, and Compliance Audits – each aligned with well-known frameworks like NIST, ISA/IEC 62443, and ISO 27001 to ensure best-practice coverage. We deliver clear, professional insights in simple language so that decision-makers in industrial and critical infrastructure sectors can take informed action.

Gap Assessment

Our Gap Assessment service (often called a cybersecurity gap analysis) pinpoints the discrepancies between your current OT security posture and industry standards. An OT cybersecurity gap assessment evaluates your organization’s practices against established standards and regulatory requirements such as the NIST Cybersecurity Framework, ISA/IEC 62443, and ISO/IEC 27001. We conduct a thorough review of your control systems, network architecture, and policies to uncover any weaknesses or missing controls. This IEC 62443 gap assessment approach highlights exactly where your OT security gaps lie in comparison to these benchmarks.

Key outcomes of a Gap Assessment:

  • Baseline Security Posture & Maturity: We assess your current security controls and procedures, providing a cybersecurity maturity evaluation that benchmarks your OT security program against industry best practices.

  • Detailed Gap Analysis Report: You receive a clear report showing where your cybersecurity gap analysis finds misalignments or deficiencies. Each gap is mapped to specific framework requirements (e.g. missing network segmentation, insufficient access controls) and ranked by risk.

  • Prioritized Improvement Roadmap: Danguard delivers a prioritized list of recommendations to close the gaps and elevate your security. This roadmap helps you plan investments to quickly bolster defenses and align with standards, improving both compliance and resilience.

Conducting a gap assessment gives you a strategic view of your OT security maturity. It not only identifies weaknesses before attackers can exploit them, but also provides actionable guidance to strengthen your defenses and meet cybersecurity compliance for OT standards.

Risk Assessment

In OT environments, understanding and managing risk is essential to safe and reliable operations. Our Risk Assessment service evaluates potential threats and vulnerabilities in your industrial networks to determine how they could impact your business. We follow NIST risk assessment methodologies and other proven risk management frameworks to ensure a rigorous analysis of your OT risks. This includes identifying critical assets in your production environments, analyzing possible attack scenarios, and quantifying the likelihood and impact of each risk.

What our OT Risk Assessment covers:

  1. Asset & Threat Identification: We catalog your OT assets (e.g. PLCs, SCADA systems, HMIs) and identify relevant threats to them, from malware and ransomware to insider threats and supply chain attacks. This comprehensive view sets the foundation for effective OT risk management.

  2. Vulnerability Analysis: Our experts review your current safeguards and known system vulnerabilities. We assess weaknesses unique to OT systems – such as legacy hardware, unpatched control software, or insecure remote access – that could be exploited.

  3. Risk Evaluation & Prioritization: Using criteria aligned with NIST and IEC 62443 guidelines, we evaluate the likelihood and impact of potential security incidents. Each risk is scored and ranked, giving you a clear risk profile of your operational environment. High-risk scenarios (for example, a cyber attack causing production downtime or safety hazards) are highlighted for immediate attention.

  4. Mitigation Recommendations: For every significant risk identified, Danguard provides practical mitigation steps. These may include technical controls (network segmentation, system patches), procedural improvements (incident response planning, staff training), or policy updates. The result is a tailored risk treatment plan that helps reduce your overall risk exposure and improve your security posture.

By performing a risk assessment, you gain insight into where your OT systems are most vulnerable and what the most serious threats are. This empowers your organization to proactively address risks before incidents occur, protecting operational continuity and safety. Ultimately, our risk assessments guide you toward an improved risk posture – focusing resources on the most critical vulnerabilities and ensuring robust defenses are in place.

Compliance Audit

Regulatory compliance and adherence to industry standards are crucial in the industrial and critical infrastructure sectors. Danguard’s Compliance Audit service verifies that your OT environment meets the required cybersecurity standards and regulations that apply to your operations. We perform a thorough industrial cybersecurity audit against frameworks such as ISA/IEC 62443, NIST CSF, and ISO/IEC 27001, adapting their controls to your industrial networks. (For example, IEC 62443 is a set of cybersecurity standards specifically tailored for industrial control systems​verveindustrial.com, and ISO 27001 provides a comprehensive information security management system framework applicable to OT and IT alike​.) Our team stays up-to-date with relevant guidelines and federal mandates, so we can audit your systems for compliance with both international standards and any sector-specific regulations.

During a compliance audit, we review your organization’s security policies, procedures, and technical measures in the OT environment, checking them against each requirement of the target framework or regulation. Key areas include access control, network security, incident response, system integrity, and continuous monitoring. We identify any compliance gaps – instances where your current practices fall short of the standard – and detail what remediation is needed.

Deliverables of a Compliance Audit:

  • Compliance Scorecard: A straightforward summary showing your level of conformance with each section of the chosen standard (e.g. NIST CSF categories or ISO 27001 clauses). This gives management a high-level view of where you are strong and where improvement is required in your OT security program.

  • Detailed Audit Findings: For each control requirement, we document whether it’s Met, Partially Met, or Not Met, with evidence. Any non-compliant areas are explained in plain language – for instance, if backup policies or network configurations do not meet cybersecurity compliance for OT best practices.

  • Actionable Remediation Plan: Danguard provides clear recommendations to address every gap or weakness uncovered by the audit. This may involve implementing new security controls, updating procedures, or additional staff training. We prioritize these actions so you can tackle the most critical compliance issues first. Following our guidance will put you on the fast track to align with ISO 27001 for industrial networks and achieve full compliance with OT security standards.

Undergoing a compliance audit with Danguard gives you confidence that your organization is meeting its cybersecurity obligations. Beyond avoiding penalties or downtime from non-compliance, you also demonstrate to stakeholders (customers, regulators, and partners) that your OT systems are secured according to internationally recognized standards​. This not only protects your operations but also builds trust and credibility in your commitment to security.
