Half a Million Vulnerabilities Leave Irish Businesses Exposed to Cybercriminals

Centripetal, the global leader in cybersecurity threat intelligence, today exposed critical security gaps leaving hundreds of thousands of Irish networks vulnerable to cyberattack.

Using its proprietary threat intelligence analytics platform, Centripetal has mapped cyberattack entry points across Ireland down to individual IP addresses and networks, revealing which regions, industries, and organizations face the greatest risk.

The findings are stark:

• 349,000 Irish networks (3.6% of the total) remain unprotected from active cyber threats
• 44% have exposed vulnerabilities
• Half a million vulnerabilities exist on exposed assets across Ireland as of September 2025
• Dublin faces the highest risk, recording the greatest concentration of vulnerabilities across all industries

Centripetal's Attack Surface Map identifies specific attack vectors—the methods cybercriminals use to exploit vulnerabilities and gain unauthorized access to systems, networks, and sensitive data. This granular visibility enables organizations to understand their exact exposure and take immediate action.

The threat is active and escalating:

• 63% of compromised networks are leveraged to conduct active reconnaissance—attackers are probing systems and planning their strikes through Irish infrastructure
• 11% are acting as command-and-control centers to coordinate attacks—cybercriminals have already infiltrated these systems and are working to further seize control of other target networks
• 35% increase in active attacks launched or coordinated through Irish networks since 2024 - the scale of attacks has expanded dramatically as cybercriminals automate campaigns and target vastly more organizations simultaneously by leveraging sophisticated tools and technologies including AI.

This means thousands of Irish organizations are likely under attack right now, many without knowing it.

David Silke, Managing Director, Centripetal Ireland says, "Across Ireland, we can see that there are Critical National Infrastructure organisations that are currently exposed to attack vectors. We can see that the largest attack vector in Ireland at present are the ISPs (Internet service providers – the telecoms and hosting providers). Our technology can drill down to a granular level to show which customers of a particular provider are affected by these vulnerabilities at a street level.

"We're calling for organisations in Ireland to review their cybersecurity provision and asking them to put more emphasis on the use of threat intelligence to protect themselves. We know that only 20% of organisations currently do this. At Centripetal, our technology effectively cloaks these vulnerabilities, hiding them from attackers so they can't be targeted," says Silke.

CleanINTERNET, including its new Fusion product, blocks 99.99% of threats by providing complete network visibility. Unlike traditional solutions that only monitor traffic entering and leaving the network (north-south), Fusion also monitors internal traffic flows (east-west), creating comprehensive protection from every angle.

This dual capability means organizations can now:

• Stop external threats before they breach the network
• Detect insider threats by identifying suspicious behavior from internal users and systems
• Receive real-time alerts when unusual activity occurs, whether from outside attackers or internal sources
