Background
A regional manufacturing company developing and managing connectivity products approached Advitech to better understand and manage cybersecurity risks within their operational technology (OT) environment . While the company recognised cybersecurity as a genuine and growing threat, they felt underserved by consultancies focused on large enterprises with complex, resource‑heavy engagements. They needed practical, operationally relevant guidance that would strengthen their security posture without disrupting production or overwhelming internal teams.
Advitech’s multidisciplinary engineering expertise, combined with a risk‑based approach to OT security aligned with the AS IEC 62443 framework, made it possible to deliver exactly that.
Challenges
The client faced several common but critical challenges:
- Growing exposure to OT cybersecurity risks. Their connected equipment and cloud‑based data interactions introduced vulnerabilities inherent to modern OT systems.
- A mismatch between their needs and available market services. Many cybersecurity offerings were aimed at large, highly resourced organisations, resulting in overly complex and costly solutions.
- Operational pressure limiting the ability to implement changes. The business required a structured yet streamlined assessment process that respected business demands.
- A need for confidence in future investment decisions. Leadership needed clear, defensible data to guide cybersecurity upgrades and prioritise capital expenditure.
These concerns aligned with a broader industry trend: as OT environments become increasingly networked, risks grow and businesses must adopt structured, standards‑aligned approaches to maintain operational continuity – an issue Advitech’s OT security services were purposely designed to address.
Solution
Advitech facilitated tailored OT cybersecurity risk assessment workshops based on the AS IEC 62443 suite of standards – internationally recognised guidance for securing industrial automation and control systems.
Structured, Collaborative Workshops
The engagement was delivered through two targeted workshops designed to minimise business disruption, while actively managing vulnerabilities and threats in a pragmatic, business‑aligned way.
-
Workshop 1 – Establishing business rationale and identifying risks
-
- The team first developed a clear business rationale articulating why cybersecurity matters to the organisation – an AS IEC 62443 requirement and a critical first step in aligning stakeholders.
- Advitech then facilitated a detailed risk assessment addressing both business concerns (e.g. loss of customer data, product availability impacts) and system weaknesses (e.g. risks associated with third‑party data storage services).
- Where sufficient information existed, the client’s internal qualitative risk matrix was used to rank risks. Otherwise, actions were assigned for follow‑up investigation.
-
Workshop 2 – Prioritisation, validation and action planning
-
- Information gathered between workshops was used to finalise risk rankings.
- Advitech worked with the client to develop a prioritised, practical action plan designed for immediate implementation.
- The outputs also served as foundational material for a broader Cybersecurity Management System (CSMS), again aligned with IEC 62443 guidance.
This process reflected Advitech’s service approach of applying risk‑based OT cybersecurity measures that are operationally relevant, standards‑aligned and proportionate to the scale and complexity of the business.
Outcomes
By partnering with Advitech, the client achieved:
- A right‑sized, business‑focused cybersecurity approach. The process addressed the organisation’s maturity, resources and operational realities – avoiding the ‘one‑size‑fits‑all’ services they had previously encountered.
- Clear, defensible risk insights. Management gained visibility into vulnerabilities and their potential operational and reputational impacts.
- A prioritised roadmap for cybersecurity improvements. The action plan provided a practical and staged approach to enhancing the company’s OT security posture.
- Improved decision‑making confidence. The assessment gave leadership the evidence required to justify capital investment and target efforts where they mattered most.
- A foundation for a long‑term cybersecurity management system. The engagement delivered key inputs for establishing a CSMS aligned with AS IEC 62443.
