How NIS2 and DORA Enhance Cybersecurity for Critical Infrastructure

by ailona•

Europe’s NIS2 and DORA regulations are reshaping cybersecurity for critical infrastructure, emphasizing risk-based approaches, strategic CISO roles, and resilience. Learn how these laws drive stronger governance, practical controls, and real-world protection against escalating cyber threats.

Why Europe’s Risk-Based Cybersecurity Rules Matter Now

Cyberattacks are no longer just business problems. They threaten critical infrastructure like hospitals, power grids, and financial systems. This makes cybersecurity a matter of public safety. European regulations like NIS2 and DORA are transforming how organizations defend against these threats. These laws push companies to adopt a risk-based approach to security—focusing on what matters most.
“Compliance is not the end goal; it is a guidepost directing our security strategy,” says Freddy Dezeure, Deputy CISO for Europe at Microsoft.
The growing sophistication of cybercriminals and state-sponsored attackers means businesses must rethink their defenses. AI-driven attacks and access brokerage services are raising the stakes. These regulations require organizations to improve governance, incident reporting, and risk management to protect society’s essential services.

How NIS2 and DORA Elevate the CISO Role

Both NIS2 and DORA broaden the Chief Information Security Officer’s responsibilities. CISOs now oversee security across IT, OT, IoT, AI, and supply chains. They must report directly to boards, making cybersecurity a strategic priority. This shift means CISOs can influence decision-making at the highest levels. These laws mandate specific controls such as multifactor authentication, cryptography, and supply chain security. Furthermore, they require organizations to adopt a risk-based approach, focusing resources where the risk is highest. This enhances resilience, ensuring continuity during disruptions. Directors are also held accountable, increasing organizational commitment to cybersecurity.

Prioritizing What Truly Protects Your Business

Not all security controls offer equal value. The EU’s emphasis on risk-based cybersecurity helps organizations focus on high-impact protections. For example, over 97% of identity attacks rely on passwords, but phishing-resistant multifactor authentication blocks 99% of these attacks. Prioritizing such controls maximizes security effectiveness. Measuring key control indicators (KCIs) is vital. Inventorying ICT assets, managing privileged accounts, timely patching, and reliable backups form the foundation of strong cyber defense. These metrics enable CISOs to track progress and communicate risks clearly to stakeholders.
“Experience shows that a very limited subset of key mitigating controls can manage the most important security risks,” notes the CISO Metrics Working Group.
In conclusion, Europe’s risk-based cybersecurity regulations set a new standard for protecting critical infrastructure. They empower CISOs to be strategic leaders, prioritize impactful controls, and build resilience. For tech professionals, understanding and embracing these changes is essential to safeguarding the future. Compliance isn’t just about rules—it’s about securing the systems that society depends on.
