Is Your Organisation in NIS 2’s Scope-and Why Does It Matter Now?
For many organisations, the horizon of regulatory risk has just shifted-and in silence, the NIS 2 Directive may have turned your everyday business into one subject to some of Europe’s strictest cyber-security demands. This law is not just an update: it is a redefinition of who carries legal, operational, and board-level responsibility for information security. The old comfort of being “out of scope” is now a liability.
You only spot your compliance gap when urgency leaves no time to fix it.
The first and most strategic question is deceptively simple: Are you in scope? This is not a one-time yes or no. NIS 2 stretches definitions, folding in digital supply chains, critical services, SaaS platforms, and a sweep of industries once ignored by the first NIS regime. If your organisation is a direct provider, a digital intermediary, or even an upstream supplier to regulated clients, the risk profile has changed.
Start with an exhaustive mapping exercise. Review the official NIS 2 sector lists (Annex I and II) and monitor national regulator alerts-don’t assume old carve-outs still apply. Recent updates now prioritise inclusion over exclusion, and the burden is on you to justify if you believe you’re out of scope. Failing to document this rationale can mean failed deals, loss of trust, or urgent (and costly) fire drills when regulatory attention lands.
Boards are now on the frontline: under NIS 2, directors are personally accountable for compliance, not just organisationally. The expectation has shifted from technical oversight to boardroom-level leadership and auditable governance. If you previously shielded decision-makers under IT or operational discretion, that defence is gone. Every ISMS must now feature a record of board involvement and clear lines of attestation.
If you relied on legacy exemptions, now is the time for a reality check. Review all contracts-especially those involving regulated clients-since contractual flowdowns can create “compliance by association”. An auditor’s view: if you’re being asked for evidence, assume you are being treated as in scope.
What Sectors, Entities, and Geographies Define Your NIS 2 Footprint?
Mapping your organisation’s NIS 2 “footprint” is the foundation of compliance, yet many teams stumble by misclassifying sector boundaries or geographical responsibilities. This is where the difference between streamlined certification and a year of rework is decided.
Misclassify your sector today, and you’ll spend months unlearning faulty controls tomorrow.
Begin by matching your core services to the NIS 2 official sectoral lists:
- Anchor all main lines of business directly to Annex I (energy, banking, health, digital infrastructure) or Annex II (waste, food, manufacturing). Supply chain companies, digital marketplaces, and infrastructure platforms are often in the net even if not explicitly named.
- Identify overlap: Most businesses straddle digital and physical domains. If you operate in multiple sectors (say, providing cloud hosting and manufacturing), run dual compliance mapping and keep sector audits separate if necessary to document controls specific to each area.
- Trace your operational geography: Every jurisdiction brings its own flavour of NIS 2 implementation. If you offer services across EU borders or manage subsidiaries abroad, you must align documentation, entity registrations, and compliance protocols for each local legal entity. Start with a granular register-what is controlled from headquarters, and what is delegated?
- Review group structures: Parent, subsidiary, or branch structure? Compliance can never stop at the border of a chart-it must flow down to every operation, across borders, and out to the supply chain.
- Assign ongoing monitoring: National regulators can (and do) expand the list of sectors or entities over time. Governance must include a live monitoring role in Compliance, IT, or Legal.
The tactical move: Build and regularly update a “scope rationale table,” listing sector mapping decisions, applicable laws, and the documents/evidence that back each choice. Consider this table part of your ISMS records-no auditor, board member, or regulator will accept “we weren’t sure” as a defence.

Does Your Size or Role Trigger Direct NIS 2 Compliance?
Size is no longer a free pass. While the default thresholds are 50+ employees or €10 million turnover, NIS 2 gives regulators leeway to label even smaller businesses as “systemically important.” Contractual relationships can also deliver an unexpected compliance obligation, especially common for SaaS vendors and critical suppliers.
Assuming you’re exempt is the fastest way to be caught unprepared.
Deploy a rigorous, quarterly review:
- Employee count: Assign clear responsibility to monitor staff numbers against the 50-FTE threshold. If you have seasonal staff or cross this threshold even temporarily, document both the event and your control response.
- Turnover: Fluctuate near €10 million? Track revenue monthly and document the approach-proactive monitoring trumps retrospective scrambling.
- Sector overrides: Some verticals (notably cloud, banking, telecoms, health) enforce obligations from employee one or revenue zero. Know your sectoral rules for each branch, not just your main HQ.
- Supplier cascade: Contracts with regulated (in-scope) entities may deliver compliance obligations regardless of your own size-especially for IT providers and digital suppliers.
- Documentation: Every exclusion or special claim should be board-reviewed and logged as a formal rationale. An exemption is only as strong as the last signature and supporting evidence.
| Trigger | Risk Update | Control / SoA Link | Evidence Logged |
|---|---|---|---|
| Cross 50+ FTE threshold | Move to “important/essential” | Assign RACI, update board oversight | Employee logs, board minutes |
| Sector reclassified | Redefine operational scope | Remap policies, adjust control coverage | Email notice, mapping update |
| Fluctuating revenue | Re-test inclusion quarterly | Audit readiness, notify authority | Financial logs, notifications |
| Exemption claimed | Board-reviewed justification | Retain exemption log, update risk register | Signed exemption statement |
Quarterly, assign a compliance owner (often in Finance or GRC) and run a formal review for these triggers, updating your register, policies, and evidence log accordingly.
Have You Locked Down Your Evidence Portfolio for Audit and Board Scrutiny?
For both internal and external stakeholders, evidence-not assertion-is the new lingua franca of compliance. Digital, timestamped, board-validated artefacts are your answer to every auditor, regulator, or client demanding proof on demand.
What you document for tomorrow's regulator is amplified in today’s boardroom.
An audit-ready evidence system should include:
- Global evidence register: Not just a directory, but a dynamic filing system tracking rationale for every inclusion, exemption, or policy applied. Timestamp board and C-level approvals.
- Board authentication: No compliance document is complete without visible director or executive sign-off. Regular board minutes and digital approvals should be centrally available and mapped to every major compliance event.
- Artefact layering: File every version of key documents, meeting records, rationale memos, and change logs. An internal communication showing a risk was noted, actioned, and closed is as critical as the updated policy.
- Self-audit calendar: Running periodic mock inspections or independent spot-checks on your evidence portfolio is vital, surfacing gaps before an external stakeholder finds them. Each finding becomes a catalyst for iterative improvement.
ISMS.online natively supports this level of artefact management. With its digital evidence register, linked signoffs, and audit trails, it makes your compliance posture as transparent to boards and auditors as it is to your own team.
Every gap found in a mock audit is a win-better your team catches it than a regulator.
Schedule pulse checks on your evidence every six months-consider it an operational health check for your ISMS.

Is Your NIS 2 Registration Filed, Traceable, and Set for Real-Time Updates?
NIS 2 registration is not simply a deadline-driven formality; it’s a living demonstration of compliance maturity. Early submission builds in buffer for remediation and signals to auditors and clients your culture of preparedness.
- Early, verified submission: Keep records (screenshots, emails) of digital or manual filings and confirmation receipts. Save these as legal artefacts-requests for re-verification by regulators are growing.
- Ownership visible: Appoint a named owner for registration oversight, change submission, and update approvals. Map this to your RACI chart and make it visible to both staff and board.
- Change process integration: When your entity merges, restructures, or undergoes material business change, immediately file registration updates and retain evidence trails for rationale and regulator confirmation.
- Two-way regulator connection: Maintain consistent, documented dialogue with your national authority or sector regulator. Save every request, clarification, and update in your ISMS.
- ISMS.online linkage: Use platform features to link registry evidence, change and approval chains, and update timelines-instantly accessible and exportable for audit.
Audit-proof your registration trail-make evidence, updates, and communications always accessible for review.
Proactivity here doesn’t just avoid fines; it proves your compliance culture.
Who Owns What? Board, Management, and Staff Accountabilities Under NIS 2
Accountability is both the backbone and the Achilles’ heel of NIS 2. Every board, executive, and critical staff member must have explicit, documented compliance roles. A missing ownership path erodes your audit defence faster than any missing policy.
Internal clarity on who does what is the first thing a regulator checks and the last thing you want missing during an audit.
Essential checklist for accountable ownership:
- Board sign-off: No NIS 2 registration, policy update, or major compliance change is valid without official board or delegated executive sign-off. Keep digital approval logs and meeting minutes aggregated in one system.
- RACI mapping: Maintain a live RACI matrix-every compliance area mapped to a named staff member. Update immediately when staff change, ownership is reassigned, or after reorganisations or strategic shifts. Keep these records versioned.
- Succession protocols: Don’t allow a single point of failure. Handover, delegation, and backup protocols should be in place and evidenced whenever roles are reassigned.
- Leadership training: Assemble a training and acknowledgment register for every board member, compliance owner, and operational lead. Certificates and receipts must be dated and mapped to the ISMS.
| Role/Area | Expected Action | Evidence/Artefact | ISO/SoA Control |
|---|---|---|---|
| Board of Directors | Approve/register compliance | Signed minutes, approval logs | A.5.2 (Roles) |
| CISO/Compliance Lead | Map/monitor NIS2 operations | RACI matrix, registration submission, review schedule | A.5.4, A.5.36 (Mgmt review) |
| IT/Security Operations | Update technical controls | Incident logs, change records, training logs | A.5.7, A.8.7 |
| All staff | Complete compliance training | Training records, acknowledgement receipts | A.6.3 (Awareness) |
ISMS.online supports this artefact mapping from day one-every person, every action, every artefact, always up to date.
Documenting responsibilities now ensures speed and clarity later, when pressure is on.

Is Your Review Rhythm Preventing “Last-Mile” Audit Surprises?
The strongest compliance posture can be undermined by a single missed review or change-driven update. NIS 2’s operational pace means static, annual reviews are insufficient.
A steady review habit is your strongest audit defence and the regulator’s favourite sign of reliability.
Implement a living review schedule:
- Annual full-scope check: Audit sectors, entity size, controls, and ownership records at least once a year. Log every review, even if nothing changes.
- Change-driven notifications: Build and implement policies that trigger immediate review when critical conditions (company growth, merger, staff assignments) alter your compliance profile.
- Live logs: Use live review logs, accessible to all compliance, IT, and board-level staff. Audit logs should be instantly exportable for inspector or client requests.
- Designate legal/sector monitors: Assign dedicated resources or rotating roles for legal and sector update scanning. Use national authority feeds, sector groups, and ISMS.online’s update tools.
- Peer benchmarking: Compare key regulatory milestones and audit outcomes with industry benchmarks to anticipate expectations and spot potential blind spots.
ISMS.online’s scheduler, digital artefact linking, and notification system automate the review rhythm, making “missing a review” a thing of the past.
Auditors trust what they can trace; so should you.

Frequently Asked Questions
Who decides if your company is “essential” or “important” under NIS 2, and what’s the actionable first step?
The starting point for NIS 2 scope is always your own company’s systematic mapping-no regulator does this for you. You are responsible for reviewing every product, service, and entity against the sectors listed in Annex I (“essential entities” like energy, transport, health, and digital infrastructure) and Annex II (“important entities” such as manufacturing, food, ICT, and research) of the NIS 2 Directive, augmented by your country’s national thresholds or additions. Carefully check whether you exceed 50 staff or €10 million turnover/balance sheet-though some high-risk sectors (like cloud, DNS, or public administration) are included regardless of size, so ignore common myths about exemptions. Document the logic of your mapping, making note of edge cases and subsidiaries, and submit your status (with rationale) to your national NIS 2 authority or competent regulator; the final determination, and any questions, will come from them. Crucially, revisit your mapping after any acquisition, structural change, or regulatory update; unchanged status can trigger non-compliance if scope quietly evolves.
Make every mapping decision transparent, board-reviewed, and ready for scrutiny-registration is confidence, not guesswork.
For stepwise checklists and updates, consult ENISA’s NIS 2 Guidance or your national authority.
What supporting records should you have ready?
- Core services mapped to each NIS 2 sector (Annex I/II and national lists)
- Legal structure diagrams, including overseas subsidiaries
- Headcount and financial evidence for thresholds
- Board-reviewed mapping rationale (minutes, presentations)
- Change log documenting review cycles or organisational changes
What documentary evidence, records, and approvals are required for NIS 2 compliance (and what does “audit-ready” look like)?
True NIS 2 compliance is evidenced by a living record: not just a policy, but time-stamped, board-reviewed logs that trace your company’s scope, structure, and all compliance decisions. You’ll need:
- Sector mapping logs: that show your logic for classification, edge cases, and national sector overlays, with formal board signoff
- Payroll and financial statements: to justify size and any exemption claims, reviewed when your business changes
- Signed board/executive minutes: to demonstrate approval of all key scope, exemption, and registration decisions
- Digital registration confirmations: from competent authorities, including any correspondence, feedback, or filing artefacts
- A RACI matrix (Roles and Accountabilities): , updated for every shift in compliance duties, staff roles, or outsourced arrangements
- A centrally managed change register: , documenting every important event-mergers, growth, new market entry, group changes-that could affect scope, with a clear audit trail of who made each decision and when
Audit-readiness means producing all the above within minutes, not days, for any control, rationale, or exemption-ideally from a single ISMS platform. If you can’t demonstrate why you’re in or out of scope, with who signed off and when, you are not NIS 2 compliant.

How does NIS 2 compliance apply to groups, supply chains, and companies working across borders?
NIS 2 obligations flow down to each covered legal entity, regardless of group or supply chain complexity. If your business has subsidiaries, branches, or contractual operations in multiple EU countries-especially in different NIS 2 sectors-conduct a scope and Regulator-ID mapping for each one, not just the parent group. Some EU countries require stricter or broader coverage (“gold-plating”), so always apply the tightest standard across your markets for certainty. Each entity may need independent evidence logs, board signoff, and direct engagement with that national authority.
Group-wide or central compliance isn’t a silver bullet: ensure your mapping tracks local nuances, board accountability, and registration for every entity (not just HQ). For key suppliers or digital providers, maintain an up-to-date matrix of their regulatory status-if your critical vendor isn’t caught by NIS 2 but exposes your business to disruption, expect regulators to probe your due diligence and resilience planning as part of your own registration.
Compliance collapses when supply chains or group structures hide a material entity from mapping or evidence-don’t let oversight become exposure.

What are the most frequent errors in NIS 2 mapping and evidence-and what systems prevent them?
The leading failure points are:
- Relying on outdated or incomplete sector mappings, especially after Directive or national updates
- Claiming an exemption without fresh size/financial logs or new board signoff (after growth, restructuring, or layoffs)
- Missing, unsigned, or ambiguous board approvals for scope/exemption decisions
- Keeping evidence fragmented across spreadsheets, unsupported SharePoint folders, or staff inboxes instead of a central register
- Failing to update registers and RACI matrix after mergers, new products, or rapid staff changes
Prevent these with robust, cyclical governance:
- Schedule quarterly compliance reviews and event-triggered updates for every core register (sector, size, supply chain, RACI)
- Use digital signatures and rationale capture for every exception, exemption, or status change-every step must have a name and timestamp
- Assign a compliance lead to monitor regulatory changes, update the evidence log, inform the board, and trigger group or entity-level reviews immediately after any change
- Store every mapping, exemption, and board signoff in a central, controlled ISMS platform with strict version control
Neglecting real-time evidence or responsibility trails turns a boardroom slip into a legal liability and opens the door to fines and reputational loss.

Who is responsible for monitoring, maintaining, and reviewing NIS 2 compliance as your business and the law evolve?
NIS 2 makes compliance a board-level duty, not an IT afterthought:
- Board/Executive: holds ultimate responsibility for scope decisions, registration filings, exemption signoff, and must review/approve material changes, on record, every year and after any business trigger
- Compliance/CISO Lead: conducts the practical mapping, maintains registry logs, files required updates, and monitors legal/sector changes, reporting upward on both routine and event-driven cycles
- IT/Security Operations: manages technical controls, incident responses, and change logs that feed evidence and alert compliance to changes affecting risk/exposure
- Legal/HR: updates group policies, tracks mergers, restructures, staff role changes, and ensures all registers are aligned with current law and organisation structure
Every responsible party must be named in the RACI, with calendar-based and change-driven review triggers. Policy must match real oversight-if the board is surprised at registration, or the RACI is stale, you’re at risk. The “audit-ready” habit is simple: keep signoffs, rationale, and evidence fresh, accessible, and clearly mapped to every compliance outcome.

What does a complete NIS 2 evidence and traceability table include, and how can ISMS.online turn this into a living control loop?
A NIS 2–ready evidence table links every business or regulatory trigger to specific compliance actions, controls, and documented records, ensuring no step gets lost between boardroom and audit file. Here’s a concise operational template:
| Trigger/Event | Compliance Action / Owner | ISO 27001/SoA Ref. | Evidence (Board/Log) |
|---|---|---|---|
| Service/sector mapped | Register entity, log mapping | 4.3 / SoA | Mapping log, authority confirmation |
| Cross/exempt size threshold | Update registry, board signoff | 5.2, 6.1.3 | Payroll, signed rationale |
| Major restructure/acquisition | Update mapping, re-notify | 4.3, 9.3 | Board minutes, change log |
| Annual or trigger review | Board review, update RACI | 5.3, 9.3 | RACI, board signoff |
| Supplier change | RACI update, supply chain review | A.5.2, A.5.19 | RACI/log, due diligence file |
ISMS.online integrates these into a real-time, workflow-driven platform: every mapping, exemption, staff/board signature, and version is controlled, time-stamped, and board-exportable for any review or regulator query. Unlike static docs or spreadsheets, this makes evidence “living”: you see everything change as your business evolves, and always have an audit trail. True audit-readiness happens daily, not once a year.
Your proof of compliance isn’t what you say at audit, but what your records can show-instantly-on demand.
