What NIS2 Requires for DNS Providers (with Article Numbers)

NIS2 (Directive 2022/2555) is the European Union’s main cybersecurity directive for digital infrastructure and services, including DNS providers, TLD registries, cloud computing, data centres, and more. The law applies to both EU-based and non-EU entities offering these services to customers in the EU. For DNS providers established outside the EU, two key obligations apply:

• Appoint a representative in the EU (Article 26(3)): If your legal entity is not established in the EU but offers DNS or other listed digital services to the EU market, you must designate a representative in a Member State where you offer services. This representative is the legal point of contact and assigns jurisdiction for supervision and enforcement.
• Register your entity and service details (Article 27): After appointing your representative, you must register your entity with the competent authority in the Member State where your representative is based. Registration requires submitting legal name, trading names, addresses, contact details, sector/subsector, Member States served, and the public IP ranges used for service delivery.

Other core requirements for all in-scope providers include:

• Implementing risk management, incident handling, and business continuity measures (Article 21): These technical and organisational measures must be documented and kept up to date.
• Reporting significant incidents within 24 hours (Article 23): If a significant incident affects your DNS service, you must notify your competent authority or CSIRT within 24 hours. This is a separate obligation from GDPR or product security reporting.

Penalties for non-compliance are substantial: essential entities can be fined at least €10 million or 2% of worldwide turnover. The law is transposed by each Member State, so details of registration and supervision may differ. The representative cannot handle incident reporting or technical compliance for you—these duties remain with your organisation.

How to Choose a NIS2 DNS Compliance Provider

Choosing the right provider for NIS2 DNS compliance depends on your business structure, technical needs, and legal obligations. Here’s how to approach the decision:

• Non-EU DNS providers: If your company is not established in the EU but offers DNS or other listed digital services to EU customers, you are required to appoint a representative and register your entity. REP27 — Europe Services, SE provides this legal mandate and registration support, but does not offer DNS monitoring or scanning.
• If you need DNS monitoring, evidence packs, or compliance scans: Providers like ZeroHook, Certavia, The DNS Institute, and Fenrir SOC offer technical compliance solutions, including automated scans, monitoring dashboards, and audit evidence. These services help demonstrate compliance with NIS2 technical requirements but do not fulfill the legal representative or registration duties for non-EU entities.
• EU-based DNS providers: You do not need an external representative, but must still register and comply with technical requirements.

Consider the following decision matrix:

When comparing providers, check if they offer legal representation, technical monitoring, or both. Most do not combine both services, so you may need to contract separately for each obligation. Always confirm the scope of service and whether pricing is per domain, per server, or per incident.

What the Price Really Includes: Provider Comparison

NIS2 compliance costs vary widely depending on whether you need legal representation, DNS monitoring, or both. Here’s a breakdown of what each provider includes and excludes, based on published data:

Practical guidance: REP27 is suitable if you need only the legal NIS2 mandate and registration support. If you require technical monitoring, choose a provider like ZeroHook or Certavia, but remember you will still need to appoint a legal representative separately if you are a non-EU entity. The DNS Institute and Fenrir SOC offer scalable technical compliance solutions, with pricing that may increase with the number of domains or servers. Always request a full breakdown of included services and clarify any potential extra fees before signing up.

Hidden Costs and Exclusions

Understanding the full cost of NIS2 compliance requires looking beyond headline prices. Here are key hidden costs and exclusions to watch for:

• Per-domain or per-server pricing: Certavia’s €2,900/year covers up to 5 domains; Fenrir SOC charges per server per month. Adding more domains or servers increases costs.
• Extra fees for additional scans or consulting: Some providers may charge for extra scans, re-scans, or consulting beyond the base plan. Always check if the listed price covers all your domains and required scan frequency.
• Legal mandate and registration not included with technical monitoring providers: ZeroHook, Certavia, The DNS Institute, and Fenrir SOC do not provide legal representation or registration support for non-EU entities. You must contract separately for these services (e.g., with REP27).
• REP27 does not offer DNS scanning, incident reporting, or legal advice on national law: Their service is strictly limited to the legal mandate, registration support, documentation holding, and forwarding of authority requests. Incident reporting and technical compliance remain your responsibility.
• Notice periods, liability limits, and per-request fees: These are not always disclosed on provider websites. Carefully review contracts for any minimum commitment periods, liability caps, or additional charges for handling authority requests or documentation updates.

To avoid surprises, request a detailed service agreement and clarify what is included, what is excluded, and what triggers extra fees. If your compliance needs change (e.g., new domains, new Member States served), confirm how this will affect your costs and obligations.

How Appointment Works: Step by Step

Appointing a NIS2 representative and registering your DNS service is a multi-step process. Here’s a practical step-by-step guide based on REP27’s workflow and NIS2 requirements:

1. Check if your service is in scope: Review NIS2 Annex I and II. DNS services, TLD registries, cloud computing, data centres, content delivery networks, managed services, managed security services, online marketplaces, search engines, and social platforms are included. If your service is not listed, NIS2 may not apply.
2. Confirm you offer the service to EU customers: Offering means actively directing your service at EU customers, not just being technically reachable. Indicators include EU pricing, EU-specific terms, or European sales/support.
3. Map your legal entities: Identify which legal entity provides the DNS service to EU customers. Group structures may require separate mandates for different entities.
4. Appoint a representative in the EU: For non-EU providers, select a Member State where you offer services and appoint a representative (e.g., REP27). The representative’s location determines the competent authority for registration and supervision.
5. Gather registration data: Collect your legal name, trading names, registered address, representative’s address, contact details, sector/subsector, Member States served, and public IP ranges used for service delivery. The public IP range field often takes the longest to gather—start early.
6. Sign the mandate: REP27 can issue the mandate within 24 hours of receiving your information. The mandate must be signed before registration, as the registration form requires the representative’s details.
7. Submit registration: Complete the registration with the competent authority in the Member State where your representative is based. Registration is a standing duty and must be kept up to date.
8. Maintain and update registration: Notify the authority of any changes (e.g., new IP ranges, contact changes, new services) within the required period (often three months). Store the confirmation from the authority for audits and vendor questionnaires.

Checklist for buyers:

1. Identify if you are in scope (Annex I/II).
2. Map your legal entities and services.
3. Gather registration data (see above).
4. Request mandate from representative.
5. Submit registration after mandate is signed.
6. Store confirmation and keep records updated.

Technical compliance (risk management, incident handling, monitoring) must be arranged separately through internal resources or technical service providers.

Risks, Fines, and What Providers Usually Do Not Say

Non-compliance with NIS2 carries significant risks for DNS providers. Here’s what you need to know:

• Fines: Essential entities can be fined at least €10 million or 2% of worldwide turnover. Important entities face lower ceilings, but penalties are still substantial. Fines can be imposed for failing to appoint a representative, failing to register, or failing to implement required security measures.
• Two separate obligations: Appointing a representative and registering your entity are distinct requirements. Completing one does not satisfy the other. Both must be fulfilled for compliance.
• Technical monitoring does not replace legal mandate: Automated scans, dashboards, and evidence packs help demonstrate technical compliance but do not satisfy the legal requirement for non-EU providers to appoint a representative and register.
• Incident reporting is your responsibility: The representative does not file incident reports for you. You must have internal processes and named staff ready to meet the 24-hour reporting deadline for significant incidents.
• Legal advice on national transpositions is not included: REP27 and most technical providers do not offer legal advice on Member State-specific requirements. If you need advice on local laws or additional obligations, consult a local law firm.
• Notice periods, liability limits, and per-request fees: These are rarely highlighted on provider websites. Review contracts for minimum terms, liability caps, and extra charges for handling authority requests, updates, or documentation. Failing to update registration details (e.g., after staff changes or infrastructure updates) can itself be a breach.

What providers usually do not say: Technical compliance services are not a substitute for the legal mandate. Legal representatives do not handle technical compliance or incident reporting. Always clarify the division of responsibilities and confirm what is included in your contract.

Realistic Scenarios: What Applies and What to Do

• US SaaS with own DNS, no EU office: This company offers DNS services to EU customers but is not established in the EU. It must appoint a NIS2 representative (e.g., REP27), register its entity and service details, and implement technical compliance (risk management, incident handling, monitoring). Cheapest compliant route: appoint REP27 for the legal mandate and registration, and use a technical provider like The DNS Institute Basic or ZeroHook for DNS monitoring and evidence.
• Chinese Amazon seller: If the seller uses only Amazon’s DNS infrastructure, Amazon is the entity responsible for NIS2 compliance. The seller does not need its own NIS2 representative or registration. However, if the seller operates its own DNS for a direct-to-EU website, it must appoint a representative, register, and ensure technical compliance.
• UK online shop with own DNS: Post-Brexit, the UK is outside the EU. A UK-based online shop offering DNS services to EU customers must appoint a NIS2 representative, register, and implement technical measures. If the shop only sells through platforms (e.g., Etsy, eBay) using the platform’s DNS, the obligation falls on the platform.

These scenarios illustrate the importance of mapping your service delivery chain and understanding who is the responsible entity under NIS2. Always check if your DNS service is listed in Annex I/II and whether you are directing services at the EU market. If in doubt, document your assessment and seek specialist advice.
