Cybersecurity has evolved into a critical pillar of business resilience.
The NIS2 Directive (Directive (EU) 2022/2555) introduces a more robust and comprehensive framework for protecting network and information systems, significantly expanding both the scope of application and the obligations imposed on organizations.
In Greece, the Directive has been transposed into national legislation through Law 5160/2024, strengthening the role of the National Cybersecurity Authority and establishing the country's new cybersecurity compliance framework.
The scope of NIS2 covers organizations operating in sectors including energy, transport, banking, financial market infrastructures, healthcare, drinking water, wastewater, digital infrastructure, ICT service management, public administration, space, postal and courier services, waste management, food production and distribution, chemicals, manufacturing, digital service providers, and research.
Applicability is generally determined by the size of the organization, primarily targeting medium-sized and large entities with at least 50 employees and/or annual turnover or balance sheet assets exceeding €10 million. However, smaller organizations operating within sectors deemed particularly critical may also fall within the scope of the legislation.
Supporting NIS2 Compliance with ISO/IEC 27001 and ISO 22301
One of the first obligations for organizations subject to the Directive is registration in the Registry of Essential and Important Entities maintained by the National Cybersecurity Authority. Relevant organizations were required to complete this process within the prescribed 2025 deadlines through the dedicated electronic platform. In addition, the National Cybersecurity Authority has made available a dedicated eligibility assessment tool that enables organizations to determine whether they fall within the scope of NIS2 and understand the obligations applicable to them.
The Directive introduces a broad set of cybersecurity requirements, including cyber risk management, supply chain security, protection of network and information systems, employee awareness and training, business continuity, and disaster recovery capabilities.
Organizations are also required to report significant cybersecurity incidents to the competent authorities, providing an initial warning within 24 hours and a more detailed notification within 72 hours.
Against this backdrop, internationally recognized standards such as ISO/IEC 27001 and ISO 22301 provide valuable frameworks for organizations seeking to address NIS2 requirements effectively. ISO/IEC 27001 establishes the foundation for developing and operating an Information Security Management System (ISMS), while ISO 22301 focuses on business continuity and an organization's ability to maintain critical operations during major disruptions, including cyber incidents and cyberattacks.
Although certification against these standards is not a regulatory requirement under NIS2, both frameworks offer internationally recognized best practices for managing cybersecurity risks, strengthening organizational resilience, and ensuring business continuity.
Beyond Regulatory Compliance with Bureau Veritas
In today's increasingly complex threat landscape, NIS2 compliance should not be viewed solely as a legal obligation. It is a strategic enabler of operational resilience, business continuity, and stakeholder confidence.
Certification by an accredited and internationally recognized certification body with a global presence, such as Bureau Veritas, provides independent assurance regarding the maturity and effectiveness of an organization's management systems. It supports organizations in demonstrating alignment with NIS2 requirements while enhancing credibility and trust among customers, business partners, regulators, and other stakeholders.
Ultimately, organizations that approach NIS2 as an opportunity to strengthen governance, resilience, and cybersecurity capabilities will be better positioned to protect their operations, safeguard critical assets, and maintain a sustainable competitive advantage in an increasingly digital economy.
