A cyber risk management framework for an Irish SME is a practical, repeatable process for identifying cybersecurity threats, understanding their likelihood and impact, and putting proportionate controls in place. You do not need an enterprise framework to do it effectively — the goal is not to eliminate all risk (that is impossible) but to reduce it to a level your business can tolerate.
In practice you do it in six steps: identify your assets, assess your threats, evaluate your vulnerabilities, calculate your risk, treat your risks, and then monitor and review. This guide gives Irish SMEs a clear, practical approach based on ISO 27005 and NIST principles, stripped down to what actually matters for a business with 10 to 250 employees.
What Is Cyber Risk?
Cyber risk is the potential for financial loss, operational disruption, or reputational damage resulting from a cybersecurity incident. For Irish SMEs, this is not an abstract concept — it is the risk that a ransomware attack locks your systems for a week, that a phishing email leads to a fraudulent wire transfer, or that a data breach triggers a GDPR investigation.
Risk management is the process of identifying these threats, understanding their likelihood and impact, and putting proportionate controls in place. The goal is not to eliminate all risk — that is impossible — but to reduce it to a level your business can tolerate.
The biggest risk for most Irish SMEs is not a sophisticated nation-state attack. It is an employee clicking a phishing link on a Monday morning. Managing that risk does not require a million-euro budget — it requires awareness, basic controls, and a plan.
Four Categories of Cyber Risk
Understanding where your risks come from helps you address them systematically. Cyber risk for an SME falls into four categories.
Technical Risk
Unpatched software, weak passwords, no endpoint protection, and unsecured Wi-Fi.
Human Risk
Phishing susceptibility, no security training, shadow IT, and poor password hygiene.
Operational Risk
No incident response plan, untested backups, single points of failure, and no business continuity plan.
Compliance Risk
GDPR non-compliance, NIS2 obligations, industry regulations, and contractual requirements.
A Practical 6-Step Risk Framework
This framework is designed for Irish SMEs. It is based on ISO 27005 and NIST principles but stripped down to what actually matters for a business with 10 to 250 employees.
Identify Your Assets
Map every system, dataset, and process that keeps your business running. You cannot protect what you do not know you have. This includes customer databases, financial systems, email, cloud services, and operational technology. Output: complete asset register with business criticality ratings.
Assess Your Threats
Understand which threats are most likely to affect your business. For most Irish SMEs, the top threats are phishing, ransomware, business email compromise, and insider threats. Your industry, size, and digital footprint determine your specific threat profile. Output: prioritised threat register mapped to your business context.
Evaluate Your Vulnerabilities
Identify the gaps between your current security posture and where you need to be. This includes technical vulnerabilities (unpatched systems, weak passwords) and organisational ones (no security training, no incident response plan). Output: vulnerability assessment with severity ratings.
Calculate Your Risk
Risk is the combination of threat likelihood and potential impact. Not all risks are equal — a ransomware attack on your customer database is a different risk than a phishing email targeting a junior employee. Quantifying risk helps you prioritise spending. Output: risk matrix with likelihood vs impact scoring.
Treat Your Risks
For each risk, decide whether to mitigate (reduce it with controls), transfer (insure against it), accept (acknowledge it and monitor), or avoid (stop the activity). Most SMEs need a combination of all four approaches. Output: risk treatment plan with assigned owners and timelines.
Monitor and Review
Risk management is not a one-time exercise. Your threat landscape changes, your business evolves, and new vulnerabilities emerge. Regular reviews — at minimum quarterly — ensure your defences stay relevant and effective. Output: ongoing risk monitoring dashboard and review schedule.
