NIS2 Compliance Guide for Portuguese SMEs 2026

What is NIS2 and Why Does It Matter?

The Network and Information Security Directive 2 (NIS2) is the EU's most significant cybersecurity legislation to date. It replaced the original NIS Directive in October 2024 and dramatically expanded the scope of organisations required to implement security measures.

For Portuguese SMEs, NIS2 is not optional. Fines for violations reach 10 million euros or 2% of global annual turnover, whichever is higher.

Who Does NIS2 Apply To?

NIS2 covers Essential Entities and Important Entities. Essential sectors include energy, transport, banking, health, and digital infrastructure. Important sectors include postal services, manufacturing, food production, and digital providers.

If you supply or subcontract to organisations in these sectors, you may also fall in scope under supply chain requirements.
