NIS2 in Estonia

1. Quick SME Applicability Snapshot in Estonia

Does NIS2 apply to SMEs in Estonia?

Yes — depending on size and sector.

• Automatic applicability to medium-sized entities (≥50 employees and ≥€10 million turnover or balance sheet total) operating in covered sectors.
• Small or micro entities are included only if formally designated or operating in high-criticality sectors.
• Applies to entities established in Estonia and, in certain cases, foreign digital providers serving the Estonian market.

SMEs should evaluate whether they meet sectoral and size criteria under Estonia's national cybersecurity regime.

2. Overview of NIS2 Implementation in Estonia

Estonia is implementing the Directive through amendments to the Cybersecurity Act, which governs the security of network and information systems at national level.

The updated legislation aligns Estonia's cybersecurity framework with Directive (EU) 2022/2555, expanding obligations relating to risk management, governance, supervision, and sanctions.

The revised statute strengthens supervisory authority powers and clarifies reporting obligations while maintaining structural alignment with the Directive.

3. Scope of Application in Estonia

Estonia's scope reflects Directive minimum sector categories without confirmed expansion beyond the baseline.

4. Size Thresholds and SME Applicability in Estonia

The Directive baseline thresholds apply:

• ≥50 employees, and
• ≥€10 million annual turnover or balance sheet total.

Entities meeting both criteria within covered sectors fall automatically within scope.

Small and micro enterprises may be designated if considered critical to economic stability, public security, or essential service continuity.

Estonian authorities retain formal designation powers where systemic risk or national security considerations justify inclusion.

5. Entity Classification Framework in Estonia

Entities are categorized as:

• Essential Entities — Subject to proactive supervision, including audits and structured compliance monitoring.
• Important Entities — Primarily subject to reactive supervision triggered by significant incidents or compliance concerns.

Classification is determined by sector and size. Competent authorities may reclassify entities where operational impact or risk exposure warrants enhanced oversight.

Estonia follows the Directive's two-tier supervisory structure.

6. Cybersecurity Risk Management Requirements in Estonia
