Why is business resilience a priority today?
Historically, business resilience was treated as a standard safety net—a reactive measure consisting of an extra data center, a basic business continuity plan, an insurance policy, or a specialized team that was only activated once something had already gone wrong. This traditional approach is no longer sufficient in the face of modern volatility.
The current business landscape is defined by extreme interdependence. A single cyberattack can now paralyze entire production lines, a momentary disruption in cloud services can freeze global sales, and geopolitical tensions can instantly sever critical supply chains. Furthermore, extreme weather events are increasingly capable of causing simultaneous damage to physical infrastructure, personnel, and supplier networks. Because these crises are often interconnected, resilience has transitioned from a technical checkbox to a central pillar of corporate strategy and a direct responsibility of executive leadership.
How do European regulations influence business resilience?
The European Union has moved resilience from theoretical discussion to the core of its policy framework. Within its 2024-2029 strategy, the EU emphasizes the necessity of anticipating and managing crises, explicitly integrating the private sector into these efforts to combat modern digital threats.
A key development in this evolution is the concept of "Resilience 2.0," promoted in the 2025 strategic foresight report. This approach moves beyond mere reaction, requiring organizations to engage in early risk recognition, prepare for highly complex and overlapping scenarios, and maintain a high degree of adaptability in the face of constant uncertainty. In Greece, this transition is already codified through Law 5160/2024, which integrated the European NIS2 Directive into the national framework, establishing strict requirements for risk management and accountability.
Key elements of the NIS2 Directive
The NIS2 Directive, implemented in Greece via Law 5160/2024, mandates a fundamental shift in how organizations view security. Rather than focusing on isolated IT issues, the directive requires an "all hazards approach." This means risk management must cover a broad spectrum of threats across critical sectors, including energy, transport, healthcare, financial services, and digital infrastructure.
To ensure this framework is actionable, the National Cybersecurity Authority has taken several steps, including the creation of a register of obligated organizations and the establishment of specific security requirements for 2025. Organizations are no longer just encouraged to be secure; they are legally required to demonstrate a comprehensive management of risks that account for the diverse range of potential disruptions facing modern society.
What role does management play in enhancing resilience?
One of the most significant shifts in the regulatory landscape is the removal of cybersecurity from the exclusive domain of the IT department. Under the DORA Regulation (EU 2022/2554), financial entities are now legally obligated to maintain comprehensive ICT risk management frameworks and strictly oversee their third-party providers.
The ultimate responsibility now rests with the Board of Directors and senior management. Leadership is tasked with approving the overarching strategy, supervising ongoing risks, and formally approving business continuity plans. A resilient Board must be able to answer a critical operational question: "How quickly can we continue to function if a critical system collapses?"
To support this, the industry is moving toward more rigorous testing. In 2025, ENISA published a specialized manual for cyber resilience testing, designed to be used within the context of NIS2, DORA, and CER directives. Through simulations—such as a hypothetical 48-hour ransomware attack—businesses can identify exactly which functions will fail first and determine who is responsible for taking control during a crisis.
How do businesses view the cost of compliance?
The financial aspect of resilience presents a major challenge for many organizations. There is a significant tension between the immediate costs of compliance and the long-term benefits of stability. However, a shift in mindset is occurring: leading organizations are beginning to view resilience not as a "sunk cost" or a mere regulatory burden, but as a strategic investment in long-term viability.
With economic security and competitiveness becoming top priorities on the European Union agenda, the ability to withstand shocks is becoming a competitive advantage. Resilience is not proven when operations are running smoothly; it is proven at the exact moment a system fails. At that moment, the true value of the investment is revealed: whether the company possesses the strength, the tools, and the strategic clarity to continue operating while others falter.
What are the steps businesses must take to comply with resilience regulations?
For businesses, particularly Small and Medium Enterprises (SMEs), navigating the requirements of NIS2 and Law 5160/2024 requires a structured approach. The following steps are essential for ensuring compliance and operational readiness:
- Compliance Check: Organizations should immediately use the official compliance tool provided by the National Cybersecurity Authority to determine if they fall into the critical categories and sectors covered by the law.
- Registration: Once identified as an obligated entity, organizations must register in the special registry of obligated organizations maintained by the National Cybersecurity Authority.
- Adoption of National Security Frameworks: Companies must implement the 22 technical, organizational, and operational security measures required under the "all hazards" approach.
- Management Oversight and Accountability: The governing body must actively participate in the approval and supervision of cybersecurity policies, including the management of risks associated with third-party providers.
- Appointment of Officers and Incident Reporting: Organizations must appoint qualified Information Security Officers with clearly defined roles and responsibilities. Furthermore, they must establish strict procedures for the immediate reporting of significant cybersecurity incidents to the Authority.
Frequently asked questions
What is the NIS2 Directive?
The NIS2 Directive is a European regulation designed to enhance cybersecurity and resilience by mandating comprehensive risk management frameworks across critical sectors of the economy.
Why is management involvement crucial in resilience?
Under new regulations like DORA, management is no longer just an observer; they are legally responsible for approving strategies, overseeing risks, and ensuring that business continuity plans are robust and actionable.
How do cyber stress tests help businesses?
Cyber stress tests, such as those outlined in the 2025 ENISA manual, use simulations (like a 48-hour ransomware attack) to help businesses identify which functions are most vulnerable and clarify the chain of command during a crisis.
What sectors are covered by the NIS2 Directive?
The directive adopts an "all hazards approach" covering essential sectors including energy, transport, health, financial services, and digital infrastructure.
How can businesses view compliance as an investment?
Rather than a mere expense, compliance is a strategic investment in sustainability. It provides the tools and strength necessary to maintain operations and competitiveness during a crisis.
