What is the Greek NIS2 Self-Assessment Tool?

The Greek Self-Assessment Tool is an official cybersecurity readiness and compliance assessment platform developed by the Greek National Cybersecurity Authority (NCSA). The tool is available through the official Greek government cybersecurity portal and is intended to help organizations evaluate their cybersecurity maturity and export assessment results.

The tool is based on the EU-wide NIS2 Directive (Network and Information Security Directive), which was implemented in Greece by law 5160/2024 and the Joint Ministerial Decision no. 1689/2025. The self-assessment tool was initially available as a guide. However, in early 2026, a web-based tool with automatic scoring was launched. The assessment contains 234 questions.

The framework is mainly aimed at medium and large public and private sector organizations that constitute important and critical infrastructure for the country. The aim for these organizations is to achieve a high level of cybersecurity, in order for their network and information systems to be adequately protected from constantly evolving cyber threats, to acquire the ability to respond in a timely manner to cyberattack incidents and to immediately recover functionality and the continuity of the provision of their services.

What are the requirements for the Greek Self-Assessment Tool?

Organizations using the Greek Self-Assessment Tool are expected to evaluate their cybersecurity posture against the operational and governance requirements introduced by the NIS2 Directive. While the self-assessment itself is not a certification, it serves as a foundational readiness exercise that helps organizations identify gaps and prepare for regulatory obligations.

The tool contains 234 controls, divided into 19 thematic sections as follows:

1. Cybersecurity governance and risk management
2. Hardware and software recording
3. Secure configuration of equipment and applications
4. Control of program and service execution
5. Account management and access control
6. User authentication
7. Network security
8. Malware protection
9. Maintaining and analyzing event logs
10. Web application security
11. Remote work
12. Use of cryptography
13. Cybersecurity education and awareness
14. Risk management in the supply chain
15. Implementation of technical cybersecurity audits
16. Physical security measures for facilities
17. Backup
18. Addressing cybersecurity incidents
19. Ensuring business continuity and disaster recovery

Why is the Greek Self-Assessment Tool important?

Achieving readiness through the Greek Self-Assessment Tool provides organizations with significant operational, regulatory, and cybersecurity benefits.

Organizations improve their ability to:

• Detect cyber threats earlier
• Prevent operational disruptions
• Respond effectively to incidents
• Recover critical services quickly
• Reduce ransomware and supply chain risks
• Implement industry-specific cybersecurity requirements

Regularly conducting and submitting the required self-assessments helps an organization evaluate and improve its security posture, fostering transparency and regulatory compliance. Achieving compliance also allows for seamless integration and mapping with other global frameworks, such as ISO 27001, streamlining overall Governance, Risk, and Compliance (GRC) efforts.

How to achieve compliance?

The Centraleyes platform provides a dedicated solution for the Greek NIS2 Self-Assessment Tool, implemented as a comprehensive framework. This implementation is fully customized to align with the official Greek tool’s structure.

The platform enables organizations to:

• Maintain a centralized cyber risk registers connected to the self-assessment
• Map risks to the official requirements
• Track remediation activities
• Monitor risk treatment progress
• Automate evidence collection

Centraleyes enables organizations to maintain centralized evidence repositories and generate audit-ready reports that demonstrate alignment with the self-assessment cybersecurity requirements and Greek regulatory expectations.

For automated gap analysis and remediation, the platform provides instant scoring updates and built-in gap detection, automatically flagging missing artifacts. You can leverage the 20 pre-created policy templates tailored to the assessment’s policy questions to rapidly address gaps.

Through integrated risk management, the framework includes a dedicated Risk Register and is smart-mapped to popular frameworks like the CIS Controls, ISO 27001, and NIST CSF. This ensures that compliance efforts simultaneously build a stronger security posture.

By leveraging Centraleyes’ automated tasks, smart-mapping, and built-in policy templates, organizations can significantly accelerate their path to readiness. The Centraleyes platform will move the assessment process from a manual, offline system to a streamlined, platform-based workflow that ensures accurate, reliable results.
