Why DNS Resilience Is Now a Boardroom Imperative for Every Registry
DNS resilience for top-level domain (TLD) registries has outgrown its roots as a technical talking point. In today’s risk-driven boardrooms, uptime, supplier control, and incident response choreography are the backbone of digital reputation and enterprise trust. The NIS 2 Directive lands squarely in that arena: it no longer allows directors to delegate DNS decisions to IT; instead, it binds each board member’s name to the resilience of the domain namespace they operate.
Stakeholders now treat a DNS outage as a direct board-level failure. The regulatory, citizen, and enterprise expectation is simple: DNS downtime means not just lost revenue or service degradation, but a visible blow to leadership credibility. Board discussions pivot around harsh new questions: Could a DNS issue cut off a national service, breach a critical SLA, or prompt a regulator’s “explain yourself” call within 24 hours? Trust hinges on proof, not assurance. When incidents make headlines, procurement decisions stall, reputational overhangs drag on for quarters, and even share prices can wobble.
The organisation’s trust is anchored to DNS uptime-every unplanned outage erodes confidence in leadership as much as infrastructure.
A modern registry’s DNS resilience is a sum of every upstream, backup, SLA, and vendor in its orbit. Board portals and audit committees must now regularly review DNS supply chain KPIs, contractor incident histories, and real-time compliance dashboards as critically as financials. Anything less opens the gates to regulatory censure, procurement exclusion, and lingering brand damage. The board, once a distant observer, is now a named actor in resilience, reputation, and response.
Resilience is choreographed-without board engagement, DNS risk becomes market risk overnight.

Who Must Now Comply Under NIS 2? The Registry’s Expanding Perimeter
NIS 2 has redefined the compliance landscape. Every TLD registry, root operator, and critical DNS supplier now wears the “essential entity” label-no exceptions, no gaps. Article 28 tightens the net: requiring live digital evidence, precise role documentation, and two-tier incident reporting within 24 and 72 hours.
TLD Scope, Recursion, and Chain-of-Custody
Gone are the days when only the registry itself mattered. Every operator of a TLD, root, or high-availability DNS service (including backup, managed, delegated, or hybrid providers) is covered. More crucially, the duty to escalate is recursive: the registry is responsible for every link-primary, backup, and third-party-and their failures or reporting delays cascade up the chain.
Auditors now look for a digital chain of trust: signed logs, contracts, and meeting minutes linking every supplier and vendor in the response flow. Fines for incomplete, botched, or delayed notifications are now real, especially if a sub-supplier muddies the evidence chain. Regulatory “defensive traceability” is the new north star for compliance, not simply passing a yearly audit.
Notification and Audit: No Room for Post-Mortem Corrections
The stopwatch starts at the “first sign” of an incident. Article 28 mandates a 24-hour initial alert (even for suspected DNS or supplier issues) and a complete root-cause-and-remediation pack within 72 hours-gaps, delays, or incomplete logs can lead to direct penalties, board scrutiny, and customer-facing disclosure requirements.
Registries are under pressure to back every claim with ISMS artefacts. ISO 27001 isn’t optional-it’s the audit floor, with each clause mapped to everyday controls.
Key ISO 27001 Bridge Table for NIS 2
| Expectation | Operationalisation | ISO 27001 / Annex A Reference |
|---|---|---|
| Clear DNS supplier inventory | Supplier registry & signed contracts | A.5.19, A.5.21, A.5.22 |
| Live incident reporting (24/72h) | Automated workflows & event logs | A.5.24, A.5.25, A.5.26 |
| Evidence-chain for supply chain | Linked logs & live dashboards | A.8.15–A.8.16, A.7.10 |
| Role-level assignment & review | Quarterly-checked RACI, audit logs | A.5.2, A.8.2, A.5.18 |
Most NIS 2 compliance failures occur not from technical weakness, but from disconnected and outdated evidence chains. (ISACA 2023 newsletter)
Registries must make the jump from “tick-box” compliance to a living, always-on system: one that lets risk, role, and evidence be retrieved in minutes, not days.

Centralise risk, incidents, suppliers, and evidence in one clean platform.
From Policy Shelfware to Operating Compliance: Registry Realism
Satisfying NIS 2 auditors is no longer about a PDF library. The winning difference is a living, testable, and instantly retrievable ISMS. Modern ISMS platforms like ISMS.online offer continuous linkage-tying DNS events and audit trails directly to mapped owners and timestamped approvals. The bar for success is not “policy awareness”-it’s live operational proof.
Automation Over Documentation
Manual sharing of screenshots, spreadsheets, and email trails is a dead end. These break under audit: they leave gaps, delayed evidence, missing owners, and expose the registry to fail points during incidents and procurement reviews. Instead, the ISMS must automate:
- Event-to-control linkages (who did what, when, and why)
- Real-time exportability (every incident, supplier drill, or policy update logged and retrievable on demand)
- Owner assignment and RACI updates as soon as suppliers or events change
RACI, SoA, and Ownership-Why Your Audit Depends On It
Every piece of NIS 2 compliance, from a supplier onboarding to an incident recovery exercise, must assign a living RACI. Quarterly updates-or better, real-time automation-are now the regulator’s standard. Delay, lapse, or ambiguity in these logs often triggers immediate evidence requests and additional scrutiny.
DNS Audit Traceability Table
| Trigger | Risk Update | Annex A Control | Evidence Logged |
|---|---|---|---|
| DNS outage/drill | Incident audit log | A.8.15, A.5.24 | Logs, notification, approvals |
| Supplier drill | Owner reassigned | A.5.19–A.5.21 | Updated RACI, drill findings |
| Audit request | Evidence snapshot | All mapped | Contracts, minutes, event logs |
| Supplier onboard | Contract signed | A.5.19–A.5.22 | Signed contracts, onboarding |
In a living ISMS, these logs and documents remain evergreen and instantly exportable-a failed audit is almost always the result of delayed, missing, or outdated RACI assignments.
DNS Supply Chain: Contracts, Drills, and the New Evidence Bar
NIS 2 eradicates assumptions about supplier compliance. The registry’s evidence responsibility runs end to end, across every DNS, backup, and managed provider. Each partner must provide “live” contractual, drill-based, and operational proof.
The weakest DNS supplier sets the upper limit for your compliance-the chain is as robust as its most neglected link.
Live Controls, Not Annual Surveys
- Contracts: Must mandate live evidence handover and require logs, tests, and full drill participation
- Supplier drills: Biannual (at a minimum) for all key suppliers; more frequent for critical or incident-prone ones
- Vendor reviews: Each review triggers an evidence update (not just a signature). Logs, drills, and incident findings become artefacts directly mapped in the ISMS.
A registry’s procurement and compliance status now moves at the speed of its supply chain’s weakest technical or audit node. In ISMS.online, live supplier dashboards, contract links, drill artefacts, and control maps offer a single-pane-of-glass for both daily and audit readiness.
A living supply chain register becomes both shield and selling point in regulated tenders.

Living Evidence: The Art of Continuous Audit-Readiness
The age of static compliance evidence is over. Today’s regulators, auditors, and buyers expect time-stamped, digital, and system-signed proof of every control, drill, contract, and board minute. “Just-in-time” evidence is a myth: living, instantly-exportable logs are the new competitive currency.
How Living Evidence Works
- Every event, drill, or contract update is logged at execution-not batched afterwards
- Each document/log is digitally tagged to owner, timestamp, and control (SoA/Annex A reference), ready for export
- Owner assignment is embedded in each step; real-time approval workflows close the RACI gap
- Quarterly (at minimum) audit simulations walk through these chains, finding weaknesses before they become failures
Living evidence is not an aspiration-it’s your first line of audit defence and procurement advantage.
Registries that wait to update after the fact-or can’t produce a living audit chain on demand-almost always lose ground during regulator reviews, procurement, or tenders.
Vendor Handoff: Lifting Supply Chain Weak Points
Achieving continuous audit-readiness requires closing gaps between registry and vendor:
- Mandate drills and artefacts in supplier contracts:
- Extract drill logs and compliance updates at every onboarding, review, or drill:
- Automate verification, evidence, and digital handoff reviews within ISMS.online:
This approach not only meets regulator expectation but turns vendor reliability into a procurement and sales differentiator.
Mastering NIS 2 Article 28: Cross-Border Incident Reporting Without Gaps
Every DNS incident with cross-jurisdiction impact (or risk thereof) multiplies the compliance burden. Reporting obligations jump-often requiring different templates, notification windows, and artefact chains in each member state. A missed or mismatched handoff can trigger EU-wide audits, fines, or “name and shame” reports across markets.
A missed 24-hour deadline-or a misaligned template-can trigger regulator escalation and extra audits in every implicated state.
Preparing for the Maze: Notification Matrix & Simulation
- Maintain an active matrix: of notification requirements, contacts, templates, and evidence needs for each jurisdiction
- Assign clear ownership: an individual responsible for end-to-end management of cross-border DNS events, from initial alert to logging and local follow-up
- Archive every notification, template, and jurisdictional doc-not just the “sent” artefact, but full workflow incl. delivery receipts and timeline logs
Quarterly simulated incidents (“tabletop” or live) must traverse every jurisdiction’s unique obligation, surfacing template or role gaps, and driving instant configuration updates where needed.
Cross-border reporting readiness is a moving target-systems must auto-alert when templates or jurisdictional obligations change.

Turning NIS 2 Compliance into Registry Trust Capital
For TLD registries, NIS 2 is more than a cost-done right, it strengthens reputation, accelerates procurement cycles, and becomes a buying signal. Registries fielding real-time dashboards, live risk registers, and instant notification status logs are outperforming those still reliant on PDFs, consultants, or “compile it when asked” workflows.
Compliance excellence shifts from cost to value when living proof is surfaced at every business touchpoint. (Deloitte: NIS 2 as Registry ROI)

Frequently Asked Questions
How does Article 28 of NIS 2 transform breach notification for TLD registries, and what evidence are regulators now demanding?
Article 28 of NIS 2 upgrades breach notification from an afterthought into a real-time discipline. For TLD registries, it means you must document every step-initial alert, escalation, supplier handoff, and follow-up-with timestamped, uneditable records and rapid exportability. Regulators expect to receive not just a written report, but a living timeline that shows, in detail, how you recognised, communicated, and managed a notifiable incident.
Every audit now starts with, Show us your logs-can you export the full notification trail for every incident, board audience, and country at the click of a button?
Evidence the regulator will hunt for:
- Initial notification within 24 hours: You’re expected to have a live, immutable log showing the exact time the incident was recognised and reported to authorities-no delays, no manual edits.
- Comprehensive 72-hour follow-up: Article 23 and 28 require a detailed timeline, mitigation steps, and evidence of supplier communication. This needs to be structured for rapid audit (not buried in emails).
- Multi-jurisdictional traceability: If your registry or DNS operations cross borders, logs must be exportable in specific templates-e.g., BSI for Germany, ANSSI for France-at a moment’s notice.
- Role-based action tracking: The evidence must show “who did what, when,” through RBAC (role-based access control) logs, mapping notifications to owners and escalation paths.
ISO 27001 Bridge Table
| Expectation | Operationalisation | ISO 27001 / Annex A Ref. |
|---|---|---|
| Live 24/72h windows | Automated, exportable logs; RBAC philtres | A.5.24, A.5.25, A.5.26 |
| Decision escalation | Timeline linked to incident, supplier, board | A.5.18, A.6.2, A.7.6 |
| Multi-country export | Regulator-specific templates on demand | Clause 6.1.3, Clause 9.1 |
Smart registries arm their teams with compliance dashboards-like ISMS.online-that unify these demands, providing living, regulator-ready proof that’s defensible before any question is ever asked.
What exactly triggers the 24- and 72-hour notification rules, and why is this misunderstood?
The 24-hour clock starts with the potential for substantial disruption-not after financial damage, server loss, or media attention. If your team suspects that an incident could impact DNS continuity, confidentiality, or integrity, Article 28 says notify now-proof later. ENISA and most national regulators penalise “wait and see” approaches; they want evidence of rapid, even preemptive, action.
Tangible triggers include:
- Suspicious or unauthorised DNS record changes-regardless of whether impact is proven.
- Service interruption or instability in authoritative name servers.
- Incident originating from a supplier that could affect registry operations or data.
- “Near misses”: threats that were stopped but had the potential for harm (ENISA expects drill/test documentation here).
Most registries fail the audit not for the quality of technical controls, but because their logs can’t show when the threat was recognised or who owned each notification jump.
Key compliance moves:
- Use automated detection systems with role assignment-manual policies alone aren’t enough.
- Ensure every event-including drills and near misses-is timestamped, logged, and mapped to both internal and supplier notifications.
- Link handovers: when an incident passes between operators, supplier, or board, log every action, including acknowledgment.
A living ISMS makes this automatic; Excel and email leave too many holes.
Why does ISMS.online’s real-time dashboard approach outclass static GRC and spreadsheets in meeting NIS 2 audits?
Legacy GRC tools and spreadsheets can’t keep pace with NIS 2’s demands:
- They lack real-time logging, automated notifications, and multi-jurisdiction templates.
- Exports are slow, fragmented, and often miss board or role philtres.
- Manual entry leads to version drift and audit confusion.
By contrast, ISMS.online delivers a unified, dynamic dashboard:
- Every incident and notification is auto-logged, timestamped, and mapped to roles.
- Exports are ready-made for BSI, ANSSI, NCSC, and more.
- Drill/test records, supplier handoffs, and board exports are one-click.
- Evidence is audit-proof: regulators see the entire lifecycle at a glance, matched to their required format.
| Audit Capability | ISMS.online | GRC Legacy | Spreadsheets |
|---|---|---|---|
| Real-time log & export | ✓ (live) | ✗/✓ (slow, static) | ✗ (manual only) |
| Multi-country ready | ✓ | ✗ | ✗ |
| Drill/test linkage | ✓ (auto) | ✗ (upload req.) | ✗ (lost/missing) |
| Role/board philtre/export | ✓ (RBAC, instant) | ✗/✓ (limited) | ✗ |
The real question is: Can you answer the regulator, supplier, or board’s evidence request in under 30 minutes? If not, you leave exposure on the table.
What must supplier and DNS contracts now include to withstand NIS 2 Article 28 scrutiny?
Article 28 extends compliance risk to every supplier: DNS, hosting, and cloud partners. It’s no longer enough to rely on general SLAs or “best efforts.” Contracts must specify:
- Notification clause: “Notify registrar and authority within 24 hours with exportable log.”
- Evidence obligation: “Supply all logs, incident documentation, and drill records on demand.”
- Drill/test clause: “Participate in joint annual exercises-evidence stored for audit.”
- Escalation mapping: Named points of contact, backup roles, and defined evidence chain for every event.
| Key Contractual Area | Must-Have Wording | ISO / NIS 2 Ref |
|---|---|---|
| Notification | “Notify in <24h, with log” | Article 28, A.5.24 |
| Evidence export | “Export all incident records” | A.5.25, A.5.26 |
| Drill/test protocol | “Annual joint exercises, logged” | ENISA, ISO 27001 6.1, 9.1 |
| Named escalation | “Contact chain, backup roles” | Article 28(5), A.7.4 |
ISMS.online allows you to map every supplier contract to real-world incident and drill records-ensuring full traceability for audit defence.
How do you prove compliance across borders when regulators want country-specific evidence?
While NIS 2 sets the baseline, each national regulator may require different timelines, templates, or even lingo. Passing a UK audit is no guarantee in Germany or France.
- Notification templates: Maintain jurisdiction-specific exports (BSI, ANSSI, NCSC, etc.)-pre-mapped, not improvised at audit.
- Role-based philtres: RBAC dashboards enable the right view for directors, risk owners, or suppliers per country/incident.
- Drill/test crosswalk: Simulate incidents with cross-border authority templates-build muscle memory for every audience.
| Audit Trigger | Risk/Process Update | Control/SoA Reference | Export Example |
|---|---|---|---|
| Supplier incident (EU) | New sub-incident, escalate | ISO A.5.20, A.5.25 | Export: ANSSI log |
| DNS outage (multi-EU) | 24h notification, multi-BOD | A.5.24, A.6.8, Clause 9.1 | Export: BSI/NCSC logs |
| Board evidence request | Download by region/role | A.5.18 (RBAC), A.7.6 | Philtre: csv by role/event |
Assume tomorrow’s board or regulator asks for last quarter’s logs in every language you serve. You should never scramble to comply.
What gets registries fined most-log delays, weak contracts, or missed triggers-and how do you fix them, fast?
Most fines and failed audits arise from three blind spots:
1. Manual or static logs: Switch to a real-time dashboard that auto-logs and timestamps every action for every incident, drill, or notification.
2. Supplier contracts with missing hooks: Update agreements now to mandate NIS 2 event and evidence obligations, including all sub-providers.
3. Staff confusion over triggers: Practise recognising and documenting the moment of awareness, not just the aftermath. Train everyone on live drills and escalation protocols.
| Red Flag | Fix Action | NIS 2 / ISO Ref |
|---|---|---|
| Manual logs only | Adopt ISMS.online or equivalent | A.5.24, A.5.25 |
| Supplier contracts weak | Remediate contract clauses/logs | A.5.20, Art. 28 |
| Missed notification times | Train on triggers w/ scenarios | ENISA, A.6.3, A.6.8 |
| No cross-border template | Pre-build/test country exports | Clause 9.1, A.5.18 |
| Audit trail confusion | RBAC, direct export paths | A.5.18, A.7.4 |
Board-Ready Actions
- Schedule an export test-can you deliver country- and board-filtered incident logs in 30 minutes, per regulator request?
- Map and update supplier contracts for NIS 2 evidence hooks.
- Practise cross-jurisdictional notification exports every quarter.
- Centralise your drills/test logs and notification records-one live dashboard for all.
- Confirm role philtres and export features enable instant review by board, supplier, or regulator.
A living, exportable incident log isn’t just a tickbox anymore-it’s the difference between operational confidence and regulatory risk. Strengthen your registry with audit-ready exports, mapped contracts, and fully traceable logs to meet NIS 2 Article 28 before your next audit or incident.
