When it comes to breach resilience, achieving regulatory compliance is just the first chapter in a much longer story. This holds especially true for the EU's Network and Information Security Directive 2 (NIS 2), an EU-wide cybersecurity legislation aimed at tightening digital security in critical sectors.
For many organizations, the first instinct is to focus all attention on compliance deadlines. But compliance alone doesn’t make you secure; it only sets the baseline. The reality is that cyber threats are changing faster than legislation, and any organization that treats NIS 2 as a “one-time fix” will soon find itself exposed.
With NIS 2 now in effect (as of October 2024), each organization must assess where it falls under the extended scope. While EU member states are required to identify and list essential and important entities by 17 April 2025, proactive security leaders understand that compliance isn’t just about waiting for classification but about acting now.
The next phase
After your initial NIS 2 assessment, you'll likely have a list of gaps or opportunities for improvement (OFIs). However, without a structured approach to addressing these items, your organization can risk falling back into old habits.
The next phase is to implement a continuous improvement process that:
- Tracks every opportunity for improvement in a centralized repository.
- Categorizes issues according to the security functions they impact (govern, identify, protect, detect, respond, and recover).
- Links improvements directly to risk mitigation efforts.
- Demonstrates maturity progress over time.
This shift from compliance mode to operational resilience is what differentiates security leaders from those who are just keeping up with regulations.
The most effective approach to post-compliance NIS 2 management connects three elements:
Tracking improvements
Too often, organizations conduct assessments, identify weaknesses, and then...do nothing with the findings. Security teams get busy, priorities shift, and those crucial improvements sit in forgotten spreadsheets.
To avoid this, use a project management tool to track all identified opportunities for improvement. Each item should be categorized by:
- The security function it affects.
- Its connection to specific NIS 2 requirements.
- Its origin (e.g., threat defense assessment audit findings).
Every improvement must have an assigned owner, a deadline, and a review mechanism to ensure completion. Security is a living process, not a report that sits in a drawer.
Risk management integration
Every improvement opportunity should connect back to your risk register, creating a defensible approach that:
- Shows how each action mitigates specific risks.
- Provides clear justification for prioritization.
- Creates accountability for progress.
This also ensures that security efforts are driven by real threat intelligence and business risks rather than just regulatory requirements. Your risk register should evolve as improvements are made, capturing your organization's true security posture in real time.
Maturity measurement
How do you prove that security improvements are making a difference? By measuring maturity.
As actions are completed, update your security maturity assessment to demonstrate progress. This allows you to:
- Show tangible improvement to stakeholders.
- Validate that your security posture is strengthening.
- Maintain a defensible record of NIS 2 compliance efforts.
Without measurement, security can feel intangible. Showing maturity growth over time builds credibility with executives and regulators alike, turning cybersecurity from an expense into an investment.
The “full-circle” approach to security resilience
When you continuously track improvements, integrate risk management, and measure maturity, your compliance status strengthens. This creates what security leaders call a "full circle" approach—one where every action item contributes to multiple aspects of your security program simultaneously.
But more importantly, it moves cybersecurity from a regulatory burden to a business enabler.
The benefits
Organizations that effectively operationalize NIS 2 compliance benefit in several ways:
- A clear record of ongoing efforts to maintain and improve compliance, which ultimately reduces regulatory risk.
- Better prioritization of security investments, focusing on risk-based decision-making rather than arbitrary compliance tasks.
- Security maturity that continuously evolves rather than stagnating after the initial assessment.
- Enhanced capability to defend against evolving threats while maintaining regulatory compliance.
- A shift from reactive security to proactive resilience.
As NIS 2 becomes fully implemented across EU member states, the most successful security programs will be those that transform NIS 2 from a compliance exercise into an operational framework that delivers lasting security benefits.
