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

€21k

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.

€160M

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.

€18.9M

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

€5,600

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

6.5%

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 CategoryTypical 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 fraudUp to 6.5% of annual turnover
Reputational & client attritionHighly 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.
