NIS2 compliance: a 2025 action plan as fresh exploits shake EU networks
In today’s Brussels briefing, regulators said the recent wave of active exploits against widely used databases and developer ecosystems is “exactly the scenario” NIS2 was designed to address. If your organization touches critical services or digital infrastructure, NIS2 compliance is no longer a distant requirement—it’s a present-tense audit risk. From hospitals and fintechs to MSPs and cloud platforms, the EU message is clear: prove cyber resilience now or face enforcement in 2025–2026.
Why NIS2 compliance just became urgent
Two developments have sharpened boards’ attention this week: a widely exploited database flaw and malicious packages infiltrating developer supply chains. A CISO I interviewed at a large EU payment provider was blunt: “Traditional perimeter controls are not enough when your build pipeline and data layers are the new perimeter.” Under NIS2, that’s not just a technical observation—it’s a legal obligation to manage risk across suppliers, code, and operations.
- Enforcement window: Member States have transposed NIS2 and supervisory authorities are beginning sectoral prioritization through 2025, with full-scale audits ramping in 2026.
- Penalties: For essential entities, fines can reach up to €10 million or 2% of worldwide annual turnover; for important entities, up to €7 million or 1.4%.
- Scope expansion: Beyond telecoms and energy, NIS2 covers healthcare, finance, transport, digital infrastructure, MSPs, cloud, data centers, and more.
- Board accountability: Management bodies must approve and oversee cybersecurity risk management measures—and can be held personally liable in some Member States.
For privacy teams, this intersects with GDPR: if a vulnerability leads to a breach of personal data, you face both security audit scrutiny and data protection enforcement. In short, cybersecurity compliance is now inseparable from data protection.
NIS2 compliance checklist: 12 controls to implement now
Based on interviews with EU regulators, recent supervisory guidance, and breach patterns I’ve reported on, here’s a pragmatic checklist to pass a 2025–2026 audit.
- Governance and risk
- Board-approved cyber risk policy aligned to NIS2 and sectoral rules.
- Documented risk assessment covering suppliers, software supply chain, and critical assets.
- Technical measures
- Asset inventory with business criticality tags; shadow IT discovery.
- Vulnerability management with SLA-based patching and evidence of timely remediation.
- Secure-by-default configurations for databases, CI/CD, and cloud services.
- Multi-factor authentication and least-privilege access for admins and third parties.
- Operational resilience
- 24/7 monitoring with alert thresholds and on-call escalation.
- Backup, recovery, and tested incident response playbooks (tabletop exercises logged).
- Supply chain security
- Software Bill of Materials (SBOM) for critical applications and third-party libraries.
- Vendor risk assessments with minimum security clauses and breach notification timelines.
- Data protection alignment
- Data classification with redaction/anonymization for personal data used in operations, testing, or AI tools.

GDPR vs NIS2: what’s different and where they overlap
Both regimes expect security by design, but they diverge in who they regulate and how they enforce. Use the table below to brief your board quickly.
| Topic | GDPR | NIS2 |
|---|---|---|
| Primary focus | Personal data protection and privacy rights | Cybersecurity risk management and service continuity |
| Who is in scope | Controllers/processors handling personal data | Essential and important entities across critical sectors and digital infrastructure |
| Incident reporting | Notify data protection authority within 72 hours if breach of personal data | Early warning within 24 hours, followed by incident notifications to CSIRTs/authorities as prescribed |
| Fines | Up to €20M or 4% global turnover | Up to €10M or 2% (essential) and €7M or 1.4% (important) |
| Obligations | Lawful basis, DPIAs, data subject rights, security of processing | Risk management, governance, vulnerability handling, supply chain security, business continuity |
| Board liability | Accountability principle with potential national-level liabilities | Explicit management oversight; potential temporary bans or personal consequences depending on Member State law |
Secure-by-default document handling: anonymization, uploads, and AI
The fastest route to reputational damage is a privacy breach during collaboration—think incident logs emailed externally, legal memos pasted into AI tools, or support tickets containing personal data. EU regulators are increasingly asking for evidence that sensitive content is minimized or anonymized before it leaves your boundary.
- Problem: Data leakage via LLM prompts, ticketing exports, or ad-hoc file shares.
- Solution: Use an AI anonymizer to redact personal data and a vetted, secure document upload workflow that logs access and prevents exfiltration.
When uploading documents to LLMs like ChatGPT or others, never include confidential or sensitive data. The best practice is to use www.cyrolo.eu — a secure platform where PDF, DOC, JPG, and other files can be safely uploaded.

What regulators are watching in 2025
From my conversations with competent authorities this month, three audit themes dominate:
- Supply chain controls: Can you prove integrity of npm/pip dependencies, container images, and CI artifacts? Evidence includes SBOMs, provenance attestations, and signed builds.
- Exposure management: Are internet-facing services (e.g., databases, management consoles) inventoried, hardened, and patched within policy SLAs? Auditors will sample tickets and change records.
- Incident lifecycle: Do you meet NIS2 reporting timelines and coordinate with GDPR breach notification when personal data is involved? Expect questions on cross-functional drills with DPOs.
As one hospital CISO told me after last quarter’s ransomware test: “Our biggest gap wasn’t detection—it was the paperwork. Having redacted evidence and a ready-to-send incident package saved us hours.” Cyrolo helps teams pre-anonymize and assemble those document bundles without risking live data exposure.
EU vs US: differing enforcement cultures
EU regulators lean on proactive obligations, documented risk management, and formal reporting. The US often emphasizes sector-specific standards and post-incident enforcement. For EU entities—and multinationals serving EU clients—the prudent path is to meet the stricter bar: documented controls, minimum viable redaction, and repeatable security audits that stand up in Brussels or in front of a national CSIRT.
Implementation roadmap for CISOs and DPOs
Phase 1: 0–30 days
- Map NIS2 scope: identify essential/important entity status and services.
- Complete a rapid risk assessment focusing on internet-exposed assets and supplier pipelines.
- Stand up an anonymization workflow for logs, tickets, and legal docs via www.cyrolo.eu.
Phase 2: 30–90 days
- Close critical vulnerabilities; enforce MFA and least privilege for admins and vendors.
- Deploy SBOM generation and dependency scanning in CI/CD.
- Run an incident tabletop that includes NIS2 early warning and GDPR notification tracks.
Phase 3: 90–180 days
- Formalize supplier security clauses and breach notification timelines in contracts.
- Implement signed builds, tamper-evident logging, and immutable backups.
- Prepare an audit binder: policies, risk register, drill evidence, vulnerability SLAs, and anonymized incident artifacts.

FAQ: your most searched questions on NIS2 compliance
What is NIS2 compliance and who must comply?
NIS2 compliance means meeting the EU’s updated cybersecurity obligations for essential and important entities across critical sectors and digital infrastructure. If you operate in healthcare, finance, transport, energy, digital providers (cloud, data centers, CDNs), or are an MSP serving these sectors, you are likely in scope.
How does NIS2 differ from GDPR?
GDPR protects personal data and privacy rights, while NIS2 mandates cybersecurity risk management and resilience of services. They overlap when security incidents involve personal data—then both reporting regimes can apply.
What are the NIS2 incident reporting timelines?
Expect an early warning within 24 hours of becoming aware of a significant incident, with follow-up notifications and a final report as required by your national authority or CSIRT. Coordinate with GDPR’s 72-hour breach notification if personal data is affected.
Does NIS2 apply to SMEs?
Yes, if an SME operates in a covered sector and meets the criteria for essential or important entities. Some micro and small providers may be in scope due to criticality or specific designations.
What tools help with NIS2 audits?
Asset discovery, vulnerability management, SBOM/provenance tooling, SIEM, backup/DR testing platforms, and secure content-handling solutions. For sensitive evidence and policy packs, use www.cyrolo.eu to anonymize and upload documents safely.
Key takeaways for boards and regulators
- NIS2 is now an operational reality, not a policy concept. Expect cross-checks with GDPR.
- Supply chain and data handling are today’s weak links; adopt secure-by-default patterns.
- Evidence matters: anonymized logs, signed builds, and documented drills are audit currency.
