Public Sector Preparedness for NIS2: Where to Start?

Why NIS2 Matters to the Public Sector

NIS2 expands upon the original NIS Directive by widening the scope, toughening compliance requirements, and introducing stricter enforcement mechanisms.

Public sector bodies—especially those operating or managing critical infrastructure like energy, water, healthcare, and transportation—are now clearly in the spotlight. Under NIS2, public organizations fall into the "essential" or "important" entity categories, both of which require full compliance.

Key implications for the public sector:

• Broader coverage: Even smaller authorities can now fall within scope.
• Stricter enforcement: Significant fines and personal accountability for management.
• Higher expectations: Cyber risk management, governance, and reporting standards must be stepped up.

First Steps to NIS2 Compliance in the Public Sector

If your organization is beginning its NIS2 journey, here are the fundamental steps to take:

1. Determine Applicability

Check whether your entity is classified as essential or important under the Directive. Expect a notification from local bodies responsible for sending out the appropriate classification.

2. Conduct a Gap Analysis

Evaluate your current cybersecurity posture. What controls are already in place? Where are the gaps compared to NIS2 requirements?

3. Appoint a Responsible Lead or Team

NIS2 requires clear governance. Assigning responsibility—at the board or executive level—is key to ensuring accountability and a quick response.

4. Create a Compliance Roadmap

Build a plan that outlines how you’ll meet requirements over time. Set priorities based on risk and criticality, and align with existing frameworks (like ISO 27001 or NIST).

Key NIS2 Requirements Public Sector Must Address

To comply with NIS2, public entities need to implement a set of baseline cybersecurity measures. Here is what you should focus on:

• Risk Management Policies: Implement policies to manage and mitigate cyber risks, including multi-level threat detection.
• Incident Response Plans: Create formal processes for identifying, reporting, and responding to incidents.
• Business Continuity: Ensure continuity and recovery processes are in place for cyber disruptions.
• Supply Chain Security: Screen third-party vendors and partners for cybersecurity risk.
• Staff Training and Awareness: Regular training sessions and simulations for employees.
• 72-Hour Breach Notification Rule: Report major incidents to national authorities within 72 hours.

Common Challenges in the Public Sector

While NIS2 provides a clear framework, implementation in the public sector can face some unique hurdles:

• Legacy IT Infrastructure: Many government systems are outdated and difficult to secure.
• Budget Constraints: Limited resources make large-scale upgrades a challenge.
• Fragmented Oversight: Different teams handle cybersecurity, but they don’t always coordinate well.
• Procurement Risks: Working with vendors who may not meet compliance requirements.

Being aware of these challenges allows organizations to proactively address them through planning and partnerships.

Best Practices and Recommendations

Meeting the requirements of NIS2 isn’t just about ticking boxes—it’s about building a long-term culture of cybersecurity resilience. For public sector organizations, that means improving leadership, building stronger skills, and encouraging teamwork and ongoing progress.

Whether you're just starting out or refining your existing security posture, these tried-and-true practices can help ensure you're not only compliant but truly prepared:

• Align with International Frameworks: Use ISO 27001 or NIST as a baseline for NIS2 implementation. These frameworks provide structure, proven methodologies, and a common language for cybersecurity management.
• Foster Interdepartmental Collaboration: Ensure cybersecurity isn’t siloed—engage leadership, operations, and IT. Building awareness and responsibility across departments creates stronger defenses.
• Regular Audits and Simulations: Test your incident response and business continuity plans with real-world scenarios. These drills help identify weaknesses before a real threat exposes them.
• Leverage External Expertise: Consider public-private partnerships, consultancy support, or cross-border collaborations to boost capabilities. No one needs to tackle NIS2 alone—strategic support can make the journey faster and more effective.

Tools and Resources to Support NIS2 Readiness

The good news? You’re not starting from scratch. A growing number of resources are available to help public sector entities align with NIS2. From national guidelines to EU-level frameworks, here are some of the most helpful tools you can tap into:

• National Cybersecurity Agencies (e.g., ENISA, or your country's CERT): Offer guidance, toolkits, and compliance templates.
• EU Cybersecurity Act Guidelines: Help with understanding technical and procedural obligations.
• Government Procurement Frameworks: Can include cyber-compliant vendor lists and support services.
