NIS2 Compliance 2026: How your company can pass its first audit
Cyberattacks are increasing worldwide and affecting companies across all industries. In response, the European Union has significantly tightened the requirements for IT security with the NIS2 Directive. For many organisations, cybersecurity is therefore becoming a top-management responsibility. By June 2026 at the latest, affected companies must successfully complete their first compliance audit. Those who do not act now risk fines, reputational damage and operational restrictions.
But what does NIS2 actually mean—and how can companies prepare specifically for the first audit?
What is the NIS2 Directive?
The NIS2 Directive is the further development of the original NIS Directive and is considered the central EU directive for strengthening cybersecurity in Europe. It significantly expands both the scope of affected companies and the substantive requirements.
In addition to traditional critical infrastructures such as energy, transport or healthcare, many other sectors now fall under NIS2, including IT service providers, digital platforms, manufacturing companies and parts of the SME sector. The aim is to create a uniformly high level of security across the EU.
Why NIS2 makes cybersecurity a management responsibility
A key difference from earlier regulations: NIS2 explicitly addresses the responsibility of company leadership. Executive management and the board must ensure that appropriate security measures are implemented and reviewed regularly.
Cybersecurity is therefore no longer purely an IT topic. Strategic decisions, budget issues and risk management move into the focus of top management. As part of a compliance audit, it is examined closely whether this responsibility is being fulfilled.
Requirements of NIS2 at a glance
The NIS2 Directive obliges companies to implement a wide range of organisational and technical measures. These include, among others:
- Establishing comprehensive IT security risk management
- Implementing technical protective measures against cyberattacks
- Regular training and awareness-raising for employees
- Clear processes for incident response and reporting obligations
- Complete documentation of all security measures
These requirements form the basis for the subsequent compliance audit.
Preparing for the first NIS2 compliance audit
A successful audit begins long before the actual audit date. Companies should choose a structured approach early on to avoid time pressure and ad hoc measures.
- Review applicability and maturity level
First, it must be clarified whether and to what extent the company falls under NIS2. The current maturity level of IT security should then be assessed—ideally through a gap analysis.
- Identify and close security gaps
Based on the analysis, specific measures can be derived. Typical weaknesses are often found in access controls, patch management, backup concepts or network segmentation.
- Define and document processes
For the audit, it is not only crucial that security measures exist, but that they are clearly documented and put into practice. Policies, emergency plans and responsibilities must be described in a traceable manner.
- Involve employees
NIS2 places great emphasis on organisational measures. Regular training and awareness programmes are therefore an important component of compliance.
Documentation as the key to audit success
A common stumbling block in the compliance audit is insufficient documentation. Even well-implemented security measures can be assessed negatively in the audit if they are not properly evidenced.
Companies should therefore develop a structured documentation strategy at an early stage. These include:
- Security policies and concepts
- Risk analyses and action plans
- Logs of tests, training sessions and incidents
- Evidence of executive management involvement
These documents form the backbone of every successful audit.
Typical challenges in implementing NIS2
Many companies underestimate the organisational effort required by NIS2. In addition to technical adjustments, the directive requires a cultural shift in how cybersecurity and IT security are handled.
Particularly challenging are:
- Cross-departmental coordination
- Resource and budget planning
- Integration of existing standards (e.g. ISO 27001)
- Ongoing updating of measures
A clear project approach and external support can help overcome these hurdles.
Summary: Act now to be prepared for 2026
The NIS2 Directive sets new standards for cybersecurity and IT security in Europe. The first compliance audit by 2026 is not a formality, but a comprehensive test of organisation, technology and management.
Companies that close security gaps early, adapt processes and build up their documentation not only gain audit readiness, but also strengthen their resilience to cyber threats in the long term. NIS2 compliance is therefore not only an obligation, but a strategic investment in the company’s future viability.
