Everything you need to know about the NIS2 directive in Oesterreich: transposition law, competent authority, fines, deadlines, and how Reglyze helps SMEs become compliant.
Austria transposed NIS2 through the Netz- und Informationssystemsicherheitsgesetz 2026 (NISG 2026), adopted by Parliament in December 2025 after the country missed the EU's October 2024 deadline and received a Commission reasoned opinion in May 2025. The law enters fully into force on 1 October 2026, so unlike Germany or Belgium — where obligations already bind — Austrian entities still have a defined run-up: the smart move is to be registration-ready and have the Article 21(2) baseline evidenced before the October 2026 switch-on, not after.

Up to EUR 7 million or 1.4% of total worldwide annual turnover (whichever is higher)
These ceilings come from the directive — see how NIS2 fines are calculated, recent enforcement cases and director personal liability.
NIS2 covers 18 sectors across Annex I (essential) and Annex II (important). These are the sectors where Austria's transposition and BMI supervision focus most.
Austria's existing critical-infrastructure operators under the prior NISG regime are the clearest essential entities under NISG 2026 — grid operators, water utilities and rail/transport hubs carry continuous obligations and are the first cohort supervisors will examine once the law switches on.
Much of the estimated ~4,000 newly in-scope population is mid-sized Austrian industry — machinery, automotive suppliers, food and chemicals — pulled in as important entities once they pass the 50-employee / EUR 10M thresholds under Annex II.
Cloud providers, data centres, managed service providers and DNS/TLD operators are in scope irrespective of size. A small Austrian MSP serving regulated customers is typically caught even below the headcount threshold, and carries supply-chain obligations toward its clients.

Water supply is an Annex I sector. A utility of this size is an essential entity under NISG 2026: it must register with the NIS-Anlaufstelle by 31 December 2026, implement the Article 21(2) risk-management measures, and meet the 24h/72h/1-month incident-reporting clock once the law is in force.
Managed services and digital infrastructure fall under Annex II. Above the 50-staff / EUR 10M threshold this firm is an important entity: it faces ex-post supervision, must register, and should expect its own regulated customers to demand supply-chain assurances.
The NISG 2026 was adopted by the Austrian Parliament in December 2025 and enters fully into force on 1 October 2026 — obligations are not yet binding before that date.
Austria missed the EU's 17 October 2024 transposition deadline; the European Commission issued a reasoned opinion on 7 May 2025 before the law was finally adopted.
Roughly 4,000 Austrian organisations are expected to fall in scope as essential or important entities.
In-scope entities must register with the Austrian NIS authority within three months of entry into force (by 31 December 2026).
Failure to register, or late registration, is a separate offence punishable by fines up to EUR 50,000 (up to EUR 100,000 for repeat cases), on top of the main NIS2 penalty ceilings.
Significant incidents must be reported with a 24-hour early warning, a 72-hour notification and a one-month final report (NIS2 Article 23).
Because NISG 2026 only takes effect on 1 October 2026, active supervision and penalties apply from that date rather than today. Once in force, essential entities face proactive (ex-ante) supervision while important entities are supervised ex-post on cause. The penalty architecture mirrors the directive — up to EUR 10M / 2% for essential and EUR 7M / 1.4% for important entities — with a distinct registration-failure fine of up to EUR 50,000 (EUR 100,000 for repeat breaches). The run-up to October 2026 is the window to get registration-ready and evidence the Article 21(2) baseline.
