NIS2 / ZInfV-1

Slovenia implemented NIS2 as ZInfV-1, in force since 19 June 2025. It took the number of obliged organisations from roughly one hundred to roughly one thousand, and it moved accountability off the IT department and onto management personally.

Are you in scope?

Two questions decide it: what sector you operate in, and how large you are. Size is the easy half — the law reaches medium and large organisations, meaning fifty staff or more, or turnover above ten million euro. Sector is where most organisations get it wrong, because the list is much broader than "critical infrastructure" suggests, and because being a supplier to someone in scope pulls you in through their obligations even when you are not directly named.

Essential entities — the high-criticality sectors

  • Energy
  • Transport — road, rail, air and water
  • Banking and financial market infrastructure
  • Health
  • Drinking water and waste water
  • Digital infrastructure and managed service providers
  • Public administration
  • Space

Important entities — the other critical sectors

  • Postal and courier services
  • Waste management
  • Chemicals — manufacture and distribution
  • Food production and processing
  • Manufacturing of medical devices, electronics and machinery
  • Digital providers — marketplaces, search, social platforms
  • Research organisations

THE DATES

Where this stands today

  1. ZInfV-1 in force

  2. Deadline for first self-registration with URSIV

What it actually requires

  • Registration with URSIV, the government office that supervises and sanctions
  • Risk-management measures, documented and reviewed rather than asserted
  • Incident reporting: an early warning within 24 hours, a full notification within 72, a final report within a month
  • Supply-chain security — your suppliers become your responsibility
  • Business continuity and recovery planning, tested rather than filed
  • Training, including for the management that now carries the liability

What it costs to get wrong

Essential entities face up to €10 million or 2% of global annual turnover, whichever is higher. Important entities face up to €7 million or 1.4%. Beyond the corporate fine, ZInfV-1 provides for administrative fines against individual managers, and NIS2 allows a regulator to suspend a senior manager from their duties. This is the part that changes the conversation: the risk is no longer only the company's.
