Regulations in plain language
What the EU cybersecurity laws require, who they apply to and what happens if you are not ready. Without legal jargon.
What are these regulations?
- EU laws that tell organisations how to protect their computers, data and services from attacks and outages.
- The aim is that people do not lose power, water, healthcare or money if someone attacks a hospital, bank, public body or supplier.
- The main five are:
- NIS2For important sectors and public administration. Each EU country puts it into its own law — in Bulgaria, the Cybersecurity Act.
- DORAFor banks, insurers, payment and investment firms and their IT providers.
- GDPRFor anyone who handles personal data.
- AI ActFor companies that build or use artificial intelligence.
- Cyber Resilience ActFor makers of software and connected devices.
Who do they apply to?
- Medium and large organisations in 18 sectors — for example energy, transport, health, water, digital services, food, manufacturing and waste. Medium means 50 or more staff or over €10 million turnover.
- Public administration. Many countries go further: in Bulgaria, for example, every municipality and administrative body is covered regardless of size.
- Some companies regardless of size, for example internet service providers.
- Banks and financial firms — under DORA (EU Digital Operational Resilience Act).
- Small companies indirectly: if you supply a bank, hospital or public body, they will ask for evidence that you are a secure supplier.
What does “compliance” mean?
Doing what the law requires — and being able to show it. In practice:
- management is responsible for security and has been trained;
- you know what the risks are;
- there are rules on who can access what;
- backups can actually be restored;
- you know what to do in an attack and whom to notify;
- you check your suppliers.
A document in a drawer is not enough. You need evidence that the measures work.
Why prepare now?
- The laws already apply: DORA since 17 January 2025, and the national NIS2 (EU cybersecurity directive) laws in most EU countries — in Bulgaria since 17 February 2026.
- You do not need to wait for a letter. The obligations apply by law.
- Preparation takes weeks to months.
- After an attack you must send the first warning within 24 hours. Without preparation that is almost impossible.
- Customers and banks are already asking.
What happens if you are not ready?
- A fine for the organisation: up to €10 million or 2% of worldwide turnover, and up to €7 million or 1.4% for less critical organisations.
- Management can be held personally responsible — in Bulgaria, for example, personal fines of €500 to €5 000.
- The authority can order the breach to be made public.
- Under the GDPR — fines up to €20 million or 4% of turnover.
- Lost customers and contracts.
- Most importantly: one attack can stop your work for days.
