Understanding Your OT Cybersecurity Posture: Armexa’s OT Cybersecurity Maturity and Compliance Gap Assessments (“Gap Assessments”) are the cornerstone of establishing a strong cybersecurity posture. They provide a clear understanding of your current cybersecurity status, identify areas for improvement, and pinpoint vulnerabilities that pose the greatest risk to your operations. These assessments typically represent Step 1 in Armexa’s 3D Assessment Model, laying the foundation for more in-depth risk modelling.
Our Gap Assessment solutions provide a comprehensive view of both organization maturity, technology implementation, and operational practices. This service consists of a review of your organization’s OT cybersecurity governance (e.g., policies and standards) combined with a gap assessment workshop conducted with the subject matter experts who operate and maintain your OT systems. These assessments benchmark the organization against industry peers, standards, and best practices as well as enable them to align with regulations, and build a stronger, more resilient cybersecurity posture.
Our Approach
We understand that every organization has unique operational needs, risk profiles, and logistical constraints. Our approach combines governance review with interactive workshops and technical validation.
- Governance Review
We evaluate your OT cybersecurity policies, standards, and procedures to understand your maturity level and compliance alignment. - Gap Assessment Workshop
Conducted with your OT subject matter experts, this interactive session benchmarks your organization against industry standards such as:- NIST Cybersecurity Framework (CSF)
- ISA/IEC 62443
- API 1164 (Pipeline Control Systems Cybersecurity)
- NIST SP 800-82 Rev. 3 (Guide to OT Security)
- TSA Pipeline Security Directives
- US Coast Guard MTSA Cyber Guidelines
- Assessment Variants
Each of these assessment types offers a distinct level of depth and focus, allowing you to choose the approach that best aligns with your goals, timelines, and operational realities:- Interview-Only: Remote, high-level review via structured interviews. Ideal for: Organizations seeking a quick, initial assessment of their cybersecurity posture or those with geographical or logistical constraints.
- Validated Assessment: On-site visit, technical analysis, and infrastructure inspection. Ideal for: Organizations requiring a thorough evaluation of both technical and procedural cybersecurity controls, including physical security and compliance validation.
- M&A Abbreviated Assessment: Accelerated review for mergers and acquisitions. Ideal for: Organizations undergoing or considering corporate mergers or acquisitions, where understanding the cybersecurity landscape is essential for informed decision-making.
