NIS2 Directive — What Does It Mean for Polish Companies?
The NIS2 Directive (Network and Information Security Directive 2) represents the most significant cybersecurity regulation currently shaping the European Union's digital landscape. As Poland progresses through its national implementation process, organizations across virtually every major sector are facing new, far-reaching obligations. NIS2 substantially expands the scope of entities required to maintain formal cybersecurity programs — and the consequences of non-compliance are severe.
Who Does NIS2 Apply To?
NIS2 introduces a two-tier classification system that determines the level of obligations imposed on each organization:
- Essential Entities — organizations operating in critical sectors such as energy, transport, banking, financial market infrastructure, healthcare, drinking water, wastewater, digital infrastructure, and public administration.
- Important Entities — organizations in sectors including manufacturing, postal and courier services, waste management, food production, and digital service providers such as online marketplaces and search engines.
The directive applies to organizations with more than 50 employees or an annual turnover exceeding €10 million EUR. Smaller companies may also fall under NIS2 obligations if they are considered critical to the supply chain of essential services. This is a significant expansion compared to the original NIS1 framework, which covered a far narrower set of operators.
Key Obligations Under NIS2
NIS2 mandates a comprehensive, risk-based approach to cybersecurity. Polish companies must implement and maintain the following measures:
- Risk Management Systems — Organizations must establish formal IT security management processes, including risk assessments, security policies, and documented incident response procedures aligned with standards such as ISO/IEC 27001 or NIST CSF.
- Incident Reporting — Significant cybersecurity incidents must be reported to the relevant national authority (in Poland: CERT Polska / CSIRT NASK) within 24 hours of detection, with a full incident report submitted within 72 hours.
- Supply Chain Security — Companies are required to assess and manage cybersecurity risks posed by third-party vendors, software suppliers, and technology partners. This includes contractual security requirements and periodic supplier audits.
- Regular Security Testing — NIS2 explicitly requires organizations to conduct regular penetration tests, vulnerability assessments, and security audits to verify the effectiveness of implemented controls.
- Access Control and Authentication — Implementation of multi-factor authentication (MFA), privileged access management (PAM), and the principle of least privilege across all critical systems.
- Encryption and Data Protection — Mandatory use of encryption for data in transit and at rest, including properly configured TLS 1.2/1.3 for all web-facing services.
- Employee Awareness Training — Regular cybersecurity training programs covering phishing, social engineering, password hygiene, and secure handling of sensitive data.
- Business Continuity Planning — Documented and tested backup procedures, disaster recovery plans, and crisis management protocols.
Penalties for Non-Compliance
NIS2 introduces significantly stricter financial penalties than its predecessor. Organizations that fail to meet their obligations face:
- Essential Entities — fines of up to €10 million EUR or 2% of total annual global turnover, whichever is higher.
- Important Entities — fines of up to €7 million EUR or 1.4% of total annual global turnover, whichever is higher.
Beyond financial penalties, NIS2 also introduces personal liability for senior management. Directors and board members can be held individually responsible for cybersecurity failures, including temporary bans from holding management positions. This makes cybersecurity a board-level concern, not just an IT department issue.
GDPR and Cybersecurity — Overlapping Obligations
While NIS2 focuses on operational resilience and network security, GDPR (General Data Protection Regulation) imposes parallel obligations specifically around the protection of personal data. For most Polish companies, compliance with both frameworks simultaneously is not optional — it is a legal requirement.
Under Article 32 of GDPR, organizations must implement appropriate technical and organizational measures to ensure a level of security appropriate to the risk. In practical terms, this includes:
- Encryption of personal data — both in transit (enforced HTTPS with valid TLS certificates) and at rest (encrypted databases and storage systems).
- Access control and authentication — role-based access control (RBAC), strong password policies, and multi-factor authentication for systems processing personal data.
- Regular testing and evaluation — GDPR explicitly requires organizations to regularly test, assess, and evaluate the effectiveness of their security measures. Penetration testing and web application security audits directly fulfill this requirement.
- Breach notification within 72 hours — Personal data breaches must be reported to the Polish supervisory authority (UODO) within 72 hours of becoming aware of the breach, and affected individuals must be notified without undue delay when the breach poses a high risk to their rights.
- Data minimization and pseudonymization — Collecting only the data necessary for a specific purpose and applying pseudonymization techniques where feasible.
The intersection of NIS2 and GDPR is particularly relevant for companies operating web applications, APIs, and e-commerce platforms that handle customer data. A single vulnerability — such as an SQL injection flaw, an exposed API endpoint, or a misconfigured cloud storage bucket — can simultaneously trigger both NIS2 incident reporting obligations and GDPR breach notification requirements.
Practical Steps Toward Compliance in 2025
For Polish organizations navigating both NIS2 and GDPR requirements, a structured approach to cybersecurity is essential. Key priorities for 2025 include:
- Conducting a gap analysis to identify where current security practices fall short of NIS2 and GDPR requirements.
- Commissioning a professional web application penetration test to identify exploitable vulnerabilities in customer-facing systems.
- Performing an API security audit — particularly for REST and GraphQL APIs — to ensure that authentication, authorization, and data exposure controls are properly implemented.
- Completing a full HTTPS/TLS configuration audit to verify that all web services use strong cipher suites, valid certificates, and are free from known protocol vulnerabilities such as BEAST, POODLE, or ROBOT.
- Reviewing third-party and supply chain risks, including the security posture of SaaS providers, cloud platforms, and software vendors.
- Establishing a formal incident response plan with clearly defined roles, escalation paths, and notification procedures aligned with NIS2 and GDPR timelines.
