DNS Monitoring for NIS2 Compliance

DNS Is Explicitly in Scope

NIS2 treats DNS as critical infrastructure in its own right: DNS service providers and TLD registries are classified as essential entities, and the directive's recitals call out the security of the domain name system as vital to the functioning of the internal market. Even if your organization isn't a DNS provider, your DNS records route the services your customers depend on — and the Article 21 risk-management measures apply to the infrastructure behind those services.

Relevant Article 21 Measures

Article 21(2)(b) — Incident Handling

NIS2 requires processes for detecting, analyzing, and responding to incidents. ZoneWatcher's continuous DNS monitoring alerts your team in real time when records change unexpectedly — a common early indicator of domain hijacking or compromised provider credentials. Alerts flow through email, Slack, Microsoft Teams, Discord, or webhooks into your incident process.

Article 21(2)(c) — Business Continuity and Backup Management

Entities must maintain backups and be able to recover from disruptive incidents. ZoneWatcher keeps full snapshots of your DNS zones that can be exported as BIND zone files or CSV, giving you the data to restore records quickly if they're deleted or modified incorrectly.

Article 21(2)(d) — Supply Chain Security

Your DNS providers and registrars are part of your supply chain. ZoneWatcher monitors records across every provider you use from one place, so a compromise or misconfiguration at any single vendor is detected immediately — independent of that vendor's own logging.

Article 21(2)(i) — Asset Management

ZoneWatcher automatically discovers and inventories DNS records across all connected providers, maintaining a living register of the DNS assets behind your services. As records are added, changed, or removed, the inventory stays current without manual effort.

Meeting Article 23 Reporting Timelines

NIS2's incident reporting clock is unforgiving: an early warning to your CSIRT or competent authority within 24 hours of becoming aware of a significant incident, an incident notification within 72 hours, and a final report within one month. You can't report what you haven't detected. ZoneWatcher's real-time change detection means DNS-based incidents surface in minutes, not days — preserving as much of that 24-hour window as possible for triage and assessment.

Evidence for Supervisory Authorities

NIS2 gives national authorities audit and inspection powers, and Article 20 makes management bodies personally accountable for overseeing cybersecurity risk-management measures. ZoneWatcher provides:

• A continuously updated inventory of DNS assets across all providers
• A timestamped history of every DNS change, with previous and new values
• Evidence that monitoring and alerting are operational, not aspirational
• Exportable zone backups demonstrating recovery capability
• PDF compliance reports suitable for management reviews and inspections
