What is NIS2?

NIS2 (Network and Information Systems Directive 2) is an updated EU law that aims to strengthen cybersecurity in critical sectors, such as energy, transport, healthcare, finance and digital infrastructure. The directive replaces the previous NIS directive and places higher demands on businesses and organizations to protect their networks and systems against cyberattacks. The aim of NIS2 is to improve coordination between EU countries and ensure that all Member States have a common standard of cybersecurity.

How does NIS2 affect your business?

If your company belongs to a critical sector in the EU, you need to prepare to meet NIS2 requirements. Here are some important things to consider:

Security measures: Companies must take technical and organizational measures to protect their systems against cyber attacks and ensure the continuity of their services.
Incident reporting: All security incidents must be reported to national authorities within 24 hours of detection.
Risk management: Organizations must conduct regular risk assessments and take measures to reduce the risks of cyber attacks.
Supplier verification: Companies must ensure that their suppliers and partners also comply with NIS2 requirements.

When will NIS2 enter into force in Sweden?

NIS2 is a directive, and directives do not take effect directly—they must first be transposed into national law. The EU’s deadline for member states was October 17, 2024, but Sweden did not meet it. The Cybersecurity Act (2025:1506) implements NIS2 here, and it entered into force on January 15, 2026. At the same time, the previous Information Security Act (2018:1174) was repealed.

The requirements will be implemented in phases. The reporting service opened in February 2026, and the rules on incident reporting took effect on July 1, 2026. On October 1, 2026, the security measure requirements will take effect, including the obligation for management to receive training on them. For a business that falls under this regulation, NIS2 is therefore no longer something to prepare for—it is something you must be able to demonstrate compliance with.

Benefits of complying with NIS2

NIS2 not only poses challenges, but can also be a benefit for businesses. By complying with the Directive, businesses can strengthen their cybersecurity, increasing the trust of customers and partners. Companies that demonstrate that they are actively working to protect their systems can also gain a competitive advantage by offering secure and reliable services.
