Irish Threat Landscape

The Current Cyber Threat Landscape for Irish SMEs

Small businesses are not targeted because they are large — they are targeted because they are exposed. Here’s what that looks like in Ireland right now.


Most attacks are not sophisticated.

The majority of incidents affecting Irish small businesses involve phishing, stolen passwords, weak backups, or unpatched systems. Attackers rely on automation and scale — not elite hacking skill.


What’s actually hitting SMEs

Ransomware

Still the highest financial impact threat. Often enters via phishing email or exposed remote access. Attackers encrypt files and demand payment, sometimes threatening data leaks.

Business Email Compromise

Fraudulent invoices, fake supplier changes, or CEO impersonation emails. These attacks rely on social engineering, not malware.

AI-Enhanced Phishing

Emails are now well-written and context-aware. Grammar mistakes are largely gone. Attackers use AI tools to scale convincing campaigns.

Supply Chain Weakness

Attackers increasingly target smaller vendors to gain indirect access to larger clients. SMEs are often the entry point.


Because automation changed the economics.

Ransomware-as-a-Service and automated scanning tools allow attackers to scan thousands of systems daily for exposed remote desktop, weak passwords, or outdated software.

They are not choosing targets manually. They are harvesting whatever is vulnerable.


What makes Ireland specific

Factor Heavy use of Microsoft 365 & Gmail across SMEs
Factor ISP-supplied routers rarely hardened
Factor Limited in-house IT security expertise
Factor GDPR breach reporting obligations (72-hour window)

The risk profile is not theoretical. Irish SMEs have faced ransomware, payment diversion fraud, and credential theft in increasing numbers over the past several years.


Baseline hygiene still wins.

HIGH Multi-Factor Authentication
HIGH Offline / immutable backups
MED Patch management
MED Removing local admin rights
LOW Security awareness training

These controls prevent the majority of opportunistic attacks. Sophisticated nation-state threats are rare in the SME space. Weak fundamentals are not.
