What is NIS2?

Increasing digitalization is presenting companies and organizations with new challenges. In particular, the security of digital systems, data and services is becoming increasingly important. With the new NIS2 Directive, the European Union is creating a binding framework for greater cybersecurity in many sectors of the economy. The aim is to better protect critical infrastructures and clearly regulate the responsibilities of providers and institutions. For the affected companies in Germany, this means specific requirements, new measures and structured implementation in their own management.

Key Terms Related to NIS2

Why NIS2 is relevant for companies

The NIS2 Directive not only introduces additional obligations but also offers clear benefits for companies and the entire economy:

Greater transparency

A key aspect is strengthening cybersecurity across all relevant sectors where digitally connected processes have long been part of everyday life. Uniform rules create greater transparency in dealing with risks and threats.

Improved security of sensitive systems and digital services:

Companies benefit from the harmonization of security standards across Europe. This facilitates collaboration between different organizations and builds trust among customers and partners.

Positive effects on strategic issues

The implementation of structured risk management and clearly defined security measures provides a better basis for decision-making. Companies can identify risks early on and take targeted action.

Strengthening one’s own competitiveness

Organizations that meet high standards for security and data protection position themselves as reliable providers in the digital business world. This is a crucial factor, especially in sensitive areas such as cloud services or data processing.

What is behind the NIS2 Directive?

The NIS2 Directive is an evolution of the original NIS Directive and was adopted by the European Union to significantly strengthen cybersecurity. The background includes increasing attacks on digital infrastructure, growing dependence on digital services, and new risks to the economy and government institutions.

The central goal is to achieve a uniformly high level of security across all member states. The previous regulations have been expanded, tightened, and adapted to the current threat landscape. For companies, this primarily means greater responsibility and clearly defined requirements.

One of the most significant changes relates to the number of affected organizations. While the first NIS Directive covered only certain critical infrastructures, NIS2 now applies to significantly more sectors. These include, among others, energy, transportation, healthcare, finance, public administration, and digital service providers.

Generally, medium-sized and large entities in the sectors covered by NIS2 are affected; smaller entities may also fall within the scope in individual cases if their criticality justifies it. However, it is not only size that matters, but also the entity’s significance to society and the economy.

8 Best Practices for Implementing NIS2

Implementation of the NIS2 Directive should not wait until the final legal obligation takes effect. Many requirements concern fundamental processes, technical security concepts, and organizational issues related to responsibilities. Companies therefore benefit from establishing transparency early on and implementing the most important measures step by step.

1. Determine whether you are affected

As a first step, your company should determine whether it falls under the NIS2 requirements. The key factors here are primarily your industry, size, revenue, and the significance of the services you provide. It is also relevant whether your company operates in a regulated sector, provides essential or critical services, or may be affected through subsidiaries, locations, and affiliated institutions. Additionally, you should take a look at your suppliers and service providers, as they are part of your own value chain.

2. Define Responsibilities

NIS2 reinforces the responsibilities of senior management. Therefore, cybersecurity should not be viewed solely as a technical task, but as an issue for the entire management team. Clearly define responsibilities, document security objectives in writing, and establish regular reporting to senior management. It is also important to document decisions and actions in a transparent manner.

3. Establish a structured risk management framework

Effective risk management is a core component of NIS2. It helps identify threats early on, assess risks, and determine appropriate protective measures. To do this, you should identify critical systems, data sets, and services, assess potential outages and attacks, and prioritize areas requiring special protection. Regularly review existing security measures and adapt them as needed.

4. Implement technical and organizational measures

NIS2 requires not only policies but also concrete security measures. These should be tailored to the actual risks facing your company. This includes, for example, access controls, strong authentication, encryption of sensitive data, backup and recovery strategies, and incident response plans. Also remember to perform regular system updates and secure networks and interfaces.

5. Establish reporting procedures

In the future, security incidents must be quickly detected, assessed, and reported. Your company should therefore establish clear procedures early on. These include internal reporting channels, designated responsible parties, defined incident categories, and prepared communication templates. It is also advisable to regularly test reporting procedures so that no time is lost in the event of an emergency.

6. Include supply chains

Many risks do not originate within your own company, but rather with service providers, partners, or software vendors. That is why NIS2 also emphasizes securing the supply chain. Determine which external providers have access to systems or content, which security requirements are contractually stipulated, and whether evidence, certifications, or audits are required.

7. Raise employee awareness

Cybersecurity only works if employees recognize risks and respond appropriately. Therefore, schedule regular training sessions that address specific everyday situations. These include handling suspicious emails, creating strong passwords, using multi-factor authentication, securing sensitive content, and knowing how to respond to security incidents.

8. Choose Your Cloud Infrastructure Carefully

For many companies, a robust cloud infrastructure can be a key component of NIS2 implementation. Transparent operating models, clear data protection regulations, and verifiable security standards are crucial. When making your selection, look for data centers in Europe, high availability, reliability, security features for networks, identities, and data, as well as well-documented support processes. As a European cloud provider, STACKIT can provide a suitable foundation if your company wants to operate digital services securely and independently.

NIS2 as the Foundation of Modern Cybersecurity

The NIS2 Directive is a key component for enhancing cybersecurity in the European Economic Area. It significantly expands the scope of the previous NIS requirements and obligates many more companies to better protect their networked infrastructures.

For Germany, this entails clear legal changes that are being implemented by the federal government and overseen by the Federal Office for Information Security. Of particular importance are the mandatory requirements for risk management, risk management measures, and the reporting of security incidents. In the future, companies will bear greater responsibility for securing their information, services, and systems. At the same time, the directive offers an opportunity to strategically improve their own security and strengthen trust among customers and partners.

With structured implementation, appropriate precautions, and a modern cloud infrastructure—such as that provided by a European provider like STACKIT—organizations can efficiently meet the new requirements and securely shape their digital future.
