NIS 2 Directive

What is the NIS 2 Directive?

The Network and Information Systems (NIS) 2 Directive is a European Union-wide legislative framework aimed at enhancing cybersecurity by requiring in-scope organizations to strengthen their network and information systems. It builds on the original NIS Directive with updated requirements to address today’s evolving cyber threats. Unlike its predecessor, NIS 2 adopts a more comprehensive “all-hazards” approach, addressing everything from cyberattacks to physical incidents.

Who does NIS 2 impact?

NIS 2 applies to essential and important entities across sectors like energy, transport, healthcare, financial services, and digital infrastructure. If you operate in the EU or provide services to EU clients, you may fall within the scope of NIS 2 compliance.

Does this affect UK companies?

If your UK business operates in the EU or serves EU clients, you may fall within the scope of NIS 2 compliance—even post-Brexit. The Directive applies to organizations providing critical infrastructure or services to EU customers and may also impact third-party vendors in the supply chain.
