The NIS2 Directive significantly strengthens cybersecurity and risk management requirements for essential and important entities across the European Union. Unlike purely policy-driven approaches, NIS2 places strong emphasis on technical controls, operational readiness, and demonstrable security measures.
This page explains a reference NIS2 security architecture, showing how governance, CI/CD pipelines, and operational systems work together to meet NIS2 obligations in practice.
NIS2 Security Architecture (Overview)
“NIS2 Security Architecture – Secure Delivery and Operations”
This architecture illustrates how organizations can implement NIS2 requirements across the full lifecycle of digital services, from governance and development to production and incident response.
How to Read This Diagram
The diagram is structured from left to right, following the lifecycle of digital service delivery and operation:
- Governance & Risk Management
- Secure Development & CI/CD
- Operations & Incident Management
A cross-cutting security and evidence layer applies across all components, reflecting NIS2’s emphasis on continuous cybersecurity posture and preparedness.
Governance & Cyber Risk Management Layer
The governance layer reflects NIS2 requirements related to risk management, accountability, and organizational measures.
This layer includes:
- Cybersecurity risk assessments
- Security policies and standards
- Defined roles and responsibilities
- Management oversight and review
Under NIS2, accountability extends to executive management. Security architecture must therefore support clear ownership and demonstrable control.
Secure Development & CI/CD Layer
NIS2 explicitly requires organizations to implement secure development practices and manage risks throughout the supply chain.
In this architecture, CI/CD pipelines act as enforcement points for:
- Secure software development practices
- Access control and segregation of duties
- Security testing (SAST, dependency analysis, secrets detection)
- Supply chain risk mitigation
CI/CD pipelines ensure that security controls are applied consistently before software reaches production environments.
Operations & Incident Management Layer
The operational layer addresses NIS2 requirements for detection, response, and resilience.
Key capabilities include:
- Continuous monitoring and logging
- Incident detection and classification
- Coordinated incident response
- Recovery and service continuity mechanisms
CI/CD pipelines integrate with operations to support rapid remediation and controlled recovery following security incidents.
Supply Chain Security (Cross-Cutting Concern)
NIS2 places explicit emphasis on supply chain security. This architecture incorporates supply chain controls across development and operations:
- Dependency validation and monitoring
- Artifact integrity and provenance
- Controlled third-party integrations
- Visibility into outsourced services
These controls reduce exposure to software supply chain attacks and third-party risks.
Continuous Evidence and Accountability
Across all layers, the architecture generates continuous security evidence, including:
- Logs and monitoring data
- Security test results
- Deployment and change histories
- Incident handling records
This evidence supports regulatory supervision, incident reporting obligations, and post-incident analysis required under NIS2.
Why This Architecture Matters for NIS2
NIS2 requires organizations to demonstrate effective cybersecurity risk management, not merely document it.
This architecture enables:
- Technical enforcement of cybersecurity measures
- Continuous visibility into security posture
- Faster detection and response to incidents
- Clear accountability across teams and management
By embedding security into delivery and operations, organizations can meet NIS2 expectations sustainably.

Conclusion
NIS2 compliance starts with architecture. By integrating governance, secure development, CI/CD enforcement, and operational resilience into a unified security architecture, organizations can address NIS2 requirements proactively and consistently.
This diagram provides a clear and shared understanding of how NIS2 security obligations are implemented across modern digital systems.
