What you need to know


NIS2 came into effect across EU member states in October 2024, extending mandatory cybersecurity obligations to thousands of Irish organisations that were not previously in scope. The regulation affects sectors from healthcare and financial services to legal practices, logistics, and manufacturing.

Many businesses are still working out whether they are covered and, if so, what they are actually required to do. The penalties for non-compliance are significant; so is the reputational risk of a notifiable incident handled badly.

What the Guide Covers

From the Guide

Sean Lucas, Chief Technical Engineer talks about NIS and Penetration Testing in our Guides

“The question we hear most often is ‘are we in scope?’ The honest answer is that scope under NIS2 is broader than most people assume — and the consequences of getting that wrong rest with senior management, not just the IT team.”

Sean Lucas

Chief Technical Engineer, DNA IT Solutions

One of the most common misconceptions is that NIS2 only applies to large enterprises or critical national infrastructure. In practice, the directive covers medium-sized organisations across 18 sectors, and several Irish businesses have already discovered they are in scope through conversations with their legal advisers rather than a proactive review.

The guide includes a scope assessment checklist drawn from the NCSC Ireland guidance, which you can use to evaluate your position before speaking with a compliance professional.
