OT Security in Ireland: Two Forces Converging on Critical Infrastructure

For organisations operating operational technology and critical national infrastructure in Ireland, two pressures are arriving at the same time. The first is regulatory. The second is technical. Both are forcing organisations to rethink whether their OT environments are designed not just to prevent attacks, but to contain them and maintain operations when prevention fails. For […]

What NIS2 and the EU AI Act Expect of Critical Infrastructure Operators in Ireland

Most security architecture rests on an assumption that nobody says out loud: that the thing arriving at the perimeter has been seen somewhere before. A signature exists. An IP carries a reputation.

Addressing 3 Critical NIS2 Measures at the Network Edge

When Prevention Isn’t Enough: Why Containment Is Becoming a Regulatory Requirement

It can be tempting to rely solely on security infrastructure such as firewalls, endpoint protection solutions, and other core cybersecurity technologies for protection. However, this approach carries significant risk. Regulators across Europe now expect organisations not only to prevent breaches but also to respond swiftly, contain damage, and promptly report incidents. As a result, the […]

Bullwall’s View on NIS2 and Ransomware Containment

Cyberattacks have become more numerous and dangerous, with attackers frequently infiltrating computer systems, stealing information, and disrupting critical infrastructure such as electricity or healthcare. These disruptions can be devastating, as evidenced by the ransomware attack against the Irish Health Services Executive (HSE) network on May 14, 2021, which resulted in a months-long nationwide shutdown of […]
