The True Cost of a Cyber Incident for Irish Businesses — Beyond the €21k Headline
The average cost to remediate a cyber attack on an Irish business is €21,000. But that figure captures only the direct recovery cost. When you factor in payment fraud, productivity loss, and reputational damage, the true financial impact is significantly higher — and for many businesses, existential.
The Headline Figure Is Only the Beginning
The €21,000 average figure cited across Irish cybersecurity research represents the direct recovery cost — engaging specialists, restoring systems, investigating the incident. It is a significant number. But for most businesses that have experienced a serious cyber incident, the remediation cost is the smallest part of the story. The full financial impact encompasses five distinct cost categories.
Cost Category 1: Direct Remediation
Average cost to fully remediate a cyber attack on an Irish business. Covers incident response, forensic investigation, system restoration, and security hardening.
Cost Category 2: Payment Fraud
Payment fraud is one of the most significant and fastest-growing financial threats facing Irish businesses — directly enabled by cybersecurity failures. The Central Bank of Ireland’s Payment Fraud Statistics for 2024 paint a stark picture.
Total value of fraudulent payments in Ireland in 2024 — up nearly 25% from the previous year, with a 40% rise in the volume of fraudulent transactions, according to the Central Bank of Ireland.
For Irish SMBs, invoice redirection fraud is the dominant attack vector. A fraudster impersonates a supplier’s email, claims bank account details have changed, and redirects legitimate payments to their own account. By the time it is discovered, the money is long gone.
Lost by Irish SMEs to email-related scams — primarily invoice redirection fraud — over the two years to early 2026, with average losses of over €22,000 per incident, according to FraudSMART and the Banking & Payments Federation Ireland (BPFI).
Cost Category 3: Productivity Loss and Downtime
Average cost per hour of IT downtime for an Irish business, across direct revenue loss, staff productivity, and operational disruption.
More than half of Irish SMBs that experience a cyber attack suffer significant business downtime. For distribution and manufacturing businesses operating on tight schedules, every hour of downtime has an immediate and measurable commercial cost.
Cost Category 4: Revenue Lost to Fraud
of annual revenue lost to fraud by businesses in 2024, according to the AFP Payments Fraud and Control Survey. For a business turning over €2 million, that represents €130,000 per year in fraud-related losses.
Cost Category 5: Reputational Damage
For financial services and wealth management businesses, a breach is not just an operational event — it is a commercial crisis. High net worth individuals and institutional clients do not tolerate security failures from firms entrusted with their financial data. Client attrition following a serious breach in this sector can take years to recover from.
The Total Cost Perspective
| Cost Category | Typical Range for Irish SMB |
|---|---|
| Direct remediation | €15,000 – €50,000+ |
| Payment fraud losses | €5,000 – €250,000+ |
| Downtime & productivity | €5,600 per hour of downtime |
| Revenue lost to fraud | Up to 6.5% of annual turnover |
| Reputational & client attrition | Highly variable — can exceed all other categories combined |
The Prevention Calculus
A business with 30 users on a fully managed outsourced cybersecurity & IT package at €100 per user per month pays €36,000 per year for comprehensive, proactive protection. A single serious cyber incident, when all cost categories are considered, will typically cost multiples of that annual investment. The business case for proactive cybersecurity investment is not a matter of opinion. It is a straightforward financial calculation.
