Ireland’s cybersecurity threat landscape in 2025, as described in this Brandefense report, is shaped by dark web activity, stolen financial data, exposed credentials and ransomware. Ireland’s CSIRT-IE, part of the National Cyber Security Centre, is the national point of contact for cyber security matters. CISA describes ransomware as malware that encrypts files and often adds threats to leak stolen data.
Ireland’s digital ecosystem is facing unprecedented cyber risks. From the rapid escalation of dark web chatter to what the report describes as a 1,200% surge in stolen financial data, the threat environment has become more aggressive and complex than ever before.
