NIS2 and ISO 27001 Mapping: What Overlaps, What Doesn't, and How to Close the Gaps
If your organization already holds ISO 27001 certification, you're closer to NIS2 compliance than you think,but "closer" isn't "there." Here's exactly where the two frameworks align, where critical gaps remain, and how multi-entity organizations can build a unified approach without duplicating work.

Stop Mapping Frameworks in Spreadsheets. Manage NIS2 and ISO 27001 in One Place.
When two frameworks share 70%+ of their control requirements, managing them separately across subsidiaries isn't just inefficient,it's a risk. Here's how Priverion eliminates the duplication.
70% overlap estimate based on Priverion's internal mapping of NIS2 Article 21 requirements against ISO 27001:2022 Annex A controls
Cross-Framework Control Mapping
Map NIS2 Article 21 requirements directly to your existing ISO 27001:2022 Annex A controls. See exactly where you're already covered, where partial gaps exist, and where net-new controls are needed,without rebuilding anything from scratch. One unified view replaces dozens of cross-reference spreadsheets.
200+ hours saved in audit preparation
Medtec,ISO 27001 preparation within 6 months of deployment
Group-Wide Incident Response Workflows
NIS2's 24-hour early warning and 72-hour notification deadlines leave no room for chasing subsidiary contacts via email. Priverion's incident management workflows enforce escalation timelines across every entity in your group, auto-generate CSIRT notification templates, and create the audit trail regulators expect,all from one dashboard.
24/7 DPO support across multiple entities
Supply Chain Risk Assessment at Scale
NIS2 goes further than ISO 27001 on supply chain security,it requires you to assess each direct supplier's cybersecurity posture and embed contractual obligations. Priverion's vendor risk management module lets you run standardized assessments across all suppliers, track remediation, and maintain living evidence of due diligence that satisfies both frameworks simultaneously.
100% vendor risk assessment coverage
Zurzach Care,full vendor risk coverage achieved across all entities
AI-Assisted Risk Scoring and Gap Analysis
Priverion's AI-assisted capabilities help you draft risk assessments, score control effectiveness, and identify NIS2-specific gaps against your existing ISO 27001 controls. AI suggests,your compliance team decides. All processing happens within Swiss infrastructure. No customer data is used for model training. You get speed without sacrificing oversight or sovereignty.
60% reduction in compliance admin time
Aircraft manufacturer,first 6 months of deployment, measured against prior manual processes
Board-Ready Compliance Dashboards

NIS2 Article 21 vs. ISO 27001:2022,Where They Align, Where They Don't
This mapping shows how each NIS2 cybersecurity risk-management measure maps to ISO 27001 Annex A controls. Green means full coverage, amber means partial coverage requiring additional controls, and red means a net-new requirement with no direct ISO 27001 equivalent.
| NIS2 Article 21 Requirement | ISO 27001:2022 Annex A Controls | Coverage | Gap Analysis |
|---|---|---|---|
| Risk analysis and information system security policies | A.5.1, A.5.2, A.8.1–A.8.4 | Full | ISO 27001 risk assessment methodology directly satisfies this requirement. Ensure scope covers all NIS2-relevant systems. |
| Incident handling | A.5.24–A.5.28, A.6.8 | Partial | ISO 27001 covers incident management but not NIS2's specific 24-hour early warning and 72-hour notification timelines to CSIRTs. Requires additional workflow configuration. |
| Business continuity and crisis management | A.5.29, A.5.30, A.8.13, A.8.14 | Full | ISO 27001 continuity controls align well. Verify backup and recovery testing frequency meets NIS2 expectations. |
| Supply chain security | A.5.19–A.5.23 | Partial | ISO 27001 addresses supplier relationships but NIS2 requires assessing each direct supplier's cybersecurity posture and embedding contractual security obligations. Requires enhanced vendor risk assessments. |
| Security in network and information systems acquisition, development, maintenance | A.8.25–A.8.34 | Full | Strong alignment. ISO 27001 secure development controls cover this requirement comprehensively. |
| Policies and procedures to assess cybersecurity risk-management measures | A.5.35, A.5.36 | Full | ISO 27001 internal audit and management review processes satisfy this requirement. |
| Basic cyber hygiene practices and cybersecurity training | A.6.3, A.7.2, A.7.3 | Full | Awareness training requirements align. Verify training covers NIS2-specific scenarios. |
| Cryptography and encryption policies | A.8.24 | Full | ISO 27001 cryptographic controls provide full coverage. |
| Human resources security, access control, and asset management | A.5.9–A.5.18, A.6.1–A.6.6, A.8.1–A.8.5 | Full | Comprehensive alignment across people, access, and asset controls. |
| Multi-factor authentication and secured communication | A.8.5 (partial) | Partial | ISO 27001 addresses authentication but doesn't explicitly mandate MFA. NIS2 requires MFA for critical systems and secured emergency communications. Requires policy enhancement. |
| Management body oversight and accountability | Clause 5 (Leadership) | Gap | NIS2 introduces personal liability for management bodies and mandates cybersecurity training for executives. ISO 27001 requires management commitment but not personal accountability. Net-new governance controls required. |
| Reporting obligations to competent authorities | No direct equivalent | Gap | NIS2 mandates structured reporting to national CSIRTs within defined timelines (24h early warning, 72h notification, 1 month final report). No ISO 27001 equivalent. Requires dedicated reporting workflows. |
Full,ISO 27001 controls directly satisfy the NIS2 requirement
Partial,ISO 27001 provides a foundation but additional controls are needed
Gap,No direct ISO 27001 equivalent; net-new controls required
This mapping is based on Priverion's internal analysis of NIS2 Directive Article 21 requirements against ISO 27001:2022. Specific coverage will vary based on your organization's implementation scope and maturity.

The OneTrust alternative built for how mid-market actually works
Enterprise platforms sell you a suite designed for Fortune 500 complexity,then charge you Fortune 500 prices. Here's what changes when your privacy platform is built for multi-entity organizations, not everyone on earth.
What you get with enterprise legacy platforms
US-hosted infrastructure
Data stored in US or multi-region cloud environments, subject to FISA 702 and CLOUD Act access. Post-Schrems II, your legal team spends months on supplementary measures documentation.
Feature overload
Cookie consent, ethics hotlines, ESG modules,you pay for hundreds of features built for different buyers. Your DPO still can't find the ROPA export button.
Per-user, per-module pricing
Costs balloon every time you add a subsidiary, onboard a new compliance lead, or need an additional module. Budget conversations become quarterly fire drills.
Months-long implementation
Six-month onboarding timelines. Dedicated professional services teams. A second budget line just to get the platform running before you see any return.
200+ shallow integrations
A marketplace full of connectors that sync a few fields but break on updates. Your IT team becomes the integration support desk.
What you get with Priverion
Guaranteed Swiss data sovereignty
Swiss-built, Swiss-hosted. All data processing stays within Swiss infrastructure,outside US and EU government access regimes. Your TIA for the compliance platform itself takes five minutes, not five weeks.
Every privacy workflow, one platform
ROPA, DPIA/TIA, vendor assessments, incident management, DSR handling, AI register,all connected. We don't cover cookie consent or ethics hotlines because we'd rather be great at privacy program management than mediocre at everything.
Predictable pricing, no expansion traps
Priced by number of entities and organizational size,not per user or per module. Add compliance leads across 50 subsidiaries without a procurement negotiation for each one.
Operational in weeks, not months
Aircraft manufacturer saw a 60% reduction in compliance admin time within their first 6 months. AXA achieved 100% ROPA recertification rate with fully automated workflows.
Based on reported outcomes from Aircraft manufacturer and AXA during initial deployment
Deep integrations where they matter
Purpose-built connections to HR systems, procurement tools, and IT asset management,the systems that actually drive privacy workflows. Fewer connectors, zero maintenance headaches.
Switching doesn't mean starting over. Most teams are fully migrated within weeks.
