Maintaining a robust cybersecurity posture requires more than just individual solutions – it demands a coherent, effective program. At Armexa, we understand the unique challenges industrial organizations face, including tight OT security budgets, understaffed teams, rapidly evolving technology, and ever-changing regulations. Our goal is to ensure your operations teams are equipped to perform their jobs in a secure way, helping your organization run safely, reliably, and securely.
Armexa is composed of a team of dedicated operational technology (OT) and industrial cybersecurity experts with decades of hands-on experience from critical infrastructure facilities such as chemical plants, refineries, pipelines & terminals, and manufacturing facilities. We provide practical solutions that strengthen operational technology systems, people, and processes.
What is a Cybersecurity Program Review?
Cybersecurity Program Review evaluates the effectiveness of an organization’s cybersecurity strategy, governance, policies, and controls. The review helps identify gaps, measure alignment with business and operational objectives, and provide recommendations to strengthen cyber resilience against evolving threats.
Our Approach
We integrate governance, compliance, and technical maturity assessments to deliver actionable insights and strategic guidance.
1. Program Review & Initial Structure Assessment
The review begins with an evaluation of the program’s foundational structure. This includes:
- Governance and training organization
- Documentation such as policies, standards, procedures, and job aids
- Regulatory and compliance requirements—both current and anticipated
This phase ensures the program is aligned with operational needs and regulatory expectations.
2. NIST CSF Gap and Maturity Assessment
Armexa conducts a comprehensive gap and maturity assessment using the NIST Cybersecurity Framework (CSF) and ISA/IEC 62443 standards. This involves:
- Mapping current practices to industry standards
- Identifying areas of non-conformance or underperformance
- Evaluating governance, technical controls, and procedural effectiveness
The assessment can be tailored to different formats—ranging from remote interviews to validated site visits—depending on organizational needs.
3. Focused Deep Dive
A targeted review of the top 10–20 critical areas is conducted to:
- Uncover systemic vulnerabilities
- Highlight opportunities for improvement
- Prioritize issues based on risk and impact
This phase provides depth and clarity on the most pressing cybersecurity challenges.
4. Collaborative Workshop
Armexa facilitates a workshop with key stakeholders to:
- Review findings and threat scenarios
- Discuss consequence severity and likelihood
- Develop a shared understanding of risks and mitigation strategies
The workshop culminates in a roadmap of recommendations, offering practical steps to strengthen cybersecurity governance, technical resilience, and operational awareness.
