Best NIS2 Software for SMEs in 2026: 5 Tools Compared

The NIS2 Directive entered force across EU member states from October 2024, and it catches significantly more businesses than the original NIS Directive. Companies with at least 50 employees or €10 million in annual revenue operating in covered sectors now face incident reporting obligations, mandatory security measures, and risk management requirements under their national transposition law.

Anyone searching for the right software faces a fragmented market: some vendors come from the ISO 27001 certification world, others from the GDPR space, and only a handful have built NIS2 as a core workflow from the ground up.

This comparison evaluates five software solutions that are realistically deployable for SMEs with 50 to 500 employees across the EU. Note that all five vendors are DACH-based but available EU-wide.

1. EuroComply — Recommended for SMEs under 500 employees

EuroComply is the only solution in this comparison that offers a complete NIS2 compliance workflow in a free entry plan. The NIS2 module covers: a requirements check across all 10 security measures required under NIS2 as transposed into national law, risk assessment, incident reporting obligations overview (24h/72h deadlines), and document templates for internal policies.

Suited to: Companies with 10–500 employees that want to implement NIS2 independently without consulting fees.

Not suited to: Operators of essential services with Tier 1 obligations, or organisations whose primary goal is ISO 27001 certification.

Pricing: Free (1 system), Starter €49/month, Pro €149/month, Team €399/month.

2. heyData — Strongest DACH-native all-in-one

heyData offers one of the most complete European compliance stacks: GDPR, NIS2, ISO 27001, and the EU AI Act in a single platform. An optional external Data Protection Officer can be added via the platform.

Suited to: Companies that want to cover both NIS2 and ISO 27001 preparation in one tool and are willing to pay from ~€299/month.

Not suited to: Early-stage start-ups on tight budgets, or companies that primarily need to cover DORA, the Cyber Resilience Act, or newer EU regulations.

3. Kertos — Strongest automation for ISO + NIS2

Kertos comes from the ISO 27001 world and has integrated NIS2 as a complementary framework. The focus is on automated evidence collection for audits — useful when pursuing ISO 27001 certification in parallel.

Suited to: Scale-ups and mid-sized companies (50–300 employees) tackling ISO 27001 and NIS2 together.

Not suited to: Companies without a certification goal — Kertos is significantly more expensive if NIS2 compliance is the only objective.

4. DataGuard — Fully managed DPO service with NIS2 advisory

DataGuard positions itself primarily as a managed service with a human Data Protection Officer at its centre, not as NIS2 software. NIS2 requirements are covered through advisory services rather than structured software workflows.

Suited to: Organisations that want to fully outsource compliance decisions and are willing to pay €500–1,500/month for a managed service.

Not suited to: Companies that want to build and document compliance processes in-house.

5. OneTrust — Enterprise solution with NIS2 module

OneTrust offers NIS2 functionality as part of a much larger enterprise portfolio. Entry-level pricing typically starts around €50,000/year — economically difficult for most SMEs unless a comprehensive enterprise compliance stack is genuinely required.

Suited to: Large enterprises and group structures with a dedicated compliance team.

Not suited to: European SMEs.
