Does NIS2 apply to small businesses?

NIS2 primarily targets medium and large organizations. However, small businesses can be affected if they operate in certain sectors (like DNS services, TLD registries, or trust service providers) or if they are part of the supply chain of an essential or important entity. Check your national implementation for specific criteria.

What is the difference between NIS2 and GDPR?

GDPR focuses on protecting personal data and privacy rights. NIS2 focuses on cybersecurity: protecting networks, information systems, and critical services from cyber threats. They complement each other. GDPR requires you to protect personal data, while NIS2 requires broader cybersecurity measures. Many security controls address both.

When do I need to comply with NIS2?

The NIS2 Directive required EU Member States to transpose it into national law by 17 October 2024. Timelines vary by country. Some have implemented it on schedule, while others are still in the process. Check your national cybersecurity authority for your country's specific compliance deadline.

What counts as a significant incident under NIS2?

A significant incident is one that has caused or could cause severe operational disruption or financial loss, or has affected or could affect other organizations. Examples include ransomware attacks, data breaches affecting service availability, and supply chain compromises that impact your operations.

Can I handle NIS2 compliance myself, or do I need external help?

Many aspects of NIS2 compliance can be managed internally, especially with the right tools. The key areas (risk assessment, security policies, incident response plans, and employee training) are achievable for most businesses. AIR Tools automates the complex parts, making compliance accessible without hiring a dedicated cybersecurity team.

NIS2 Directive for Small Businesses: What You Need to Know

NIS2 Directive: What Small Businesses Need to Know

A plain-language guide to the EU Network and Information Security Directive: who it affects, what it requires, and how to prepare your business.

What Is the NIS2 Directive?

Europe's cybersecurity law, explained simply

The NIS2 Directive (Network and Information Security Directive 2) is an EU-wide cybersecurity law that entered into force on 16 January 2023. EU Member States had until 17 October 2024 to transpose it into national law. NIS2 replaces the original NIS Directive from 2016 and significantly expands which organizations must comply with cybersecurity requirements.

Why it matters for your business

NIS2 dramatically broadens the scope of EU cybersecurity regulation. Where the original NIS Directive covered only large critical infrastructure operators, NIS2 now includes medium-sized businesses across 18 sectors. If your business provides digital services, manages supply chains, or operates in healthcare, energy, transport, or other key sectors, NIS2 likely applies to you.

Who Is Affected by NIS2?

Essential and important entities across 18 sectors

Essential entities

Large organizations (250+ employees or €50M+ revenue) in critical sectors: energy, transport, banking, health, water, digital infrastructure, ICT service management, and public administration.

Important entities

Medium organizations (50+ employees or €10M+ revenue) in sectors such as postal services, waste management, chemicals, food, manufacturing, digital providers, and research.

Supply chain partners

Even if your business is smaller, you may fall under NIS2 if you are part of the supply chain of an essential or important entity. Your clients may require you to meet NIS2 standards.

Digital service providers

Cloud computing services, online marketplaces, search engines, and social networking platforms are explicitly covered regardless of size if they meet the thresholds.

Key Requirements Under NIS2

What your business must implement

Risk management measures

Implement appropriate technical, operational, and organizational measures to manage cybersecurity risks. This includes risk assessments, security policies, and regular reviews of your security posture.

Incident reporting

Report significant cybersecurity incidents to your national authority within 24 hours (early warning), with a full notification within 72 hours, and a final report within one month.

Supply chain security

Assess and manage cybersecurity risks in your supply chain. Evaluate the security practices of your direct suppliers and service providers, and include security requirements in contracts.

Business continuity

Maintain backup management, disaster recovery plans, and crisis management procedures. Ensure your business can continue operating during and after a cybersecurity incident.

Access control and encryption

Implement multi-factor authentication, access management policies, and encryption for data at rest and in transit. Control who has access to critical systems and data.

Vulnerability handling and disclosure

Establish processes for identifying, assessing, and addressing vulnerabilities in your systems. Have a policy for coordinated vulnerability disclosure.

Penalties for Non-Compliance

The consequences are significant, and personal

Essential entities

Fines up to €10 million or 2% of annual global turnover, whichever is higher. National authorities can also impose temporary bans on management exercising their functions.

Important entities

Fines up to €7 million or 1.4% of annual global turnover, whichever is higher. While supervision is lighter, the penalties are still substantial for medium-sized businesses.

Management liability

NIS2 introduces personal accountability for management. Senior leadership must approve cybersecurity measures and can be held personally liable for non-compliance. They must also undergo cybersecurity training.

Proactive enforcement

Unlike the original NIS Directive, NIS2 gives national authorities stronger enforcement powers. For essential entities, authorities can conduct proactive audits and inspections, not just respond to incidents.

How to Prepare Your Business for NIS2

A practical roadmap for SMBs

Assess whether NIS2 applies to you

Determine if your business falls into an essential or important entity category based on your sector, size (employees and revenue), and role in supply chains. Check your national implementation for specific thresholds.

Conduct a cybersecurity gap analysis

Evaluate your current security posture against NIS2 requirements. Identify gaps in risk management, incident response, access controls, and supply chain security.

Perform a risk assessment

Identify and prioritize cybersecurity risks to your business. Consider threats from both external attackers and internal vulnerabilities, including human error and system failures.

Develop security policies and procedures

Create or update policies for incident response, access control, encryption, backup management, and supply chain security. Ensure they are documented and accessible to all staff.

Set up incident reporting processes

Establish a clear process for detecting, classifying, and reporting incidents within the required timeframes: 24-hour early warning, 72-hour notification, and one-month final report.

Review your supply chain

Audit the cybersecurity practices of your suppliers and service providers. Update contracts to include security requirements and establish ongoing monitoring processes.

Train management and staff

NIS2 requires management to undergo cybersecurity training. Implement regular security awareness training for all employees, covering phishing, password hygiene, and incident reporting.

Implement continuous monitoring

Set up systems to continuously monitor your security posture, detect threats, and ensure ongoing compliance. Regular reviews and updates are essential as the threat landscape evolves.
