NAPA: sovereignty score and 8 European alternatives

NAPA is a Helsinki-based software and data company for the maritime sector. Its ship design tools cover hull form design and hydrodynamics, hydrostatics and stability, and structural design. Its ship operations products include NAPA Stability, NAPA Logbook and NAPA Voyage Optimization. According to the company, these tools support safer and more efficient maritime operations, combining software with data services.

The company is headquartered in Helsinki, Finland. Its privacy policy states that personal data is primarily stored within the EU, although employees of subsidiaries outside the EU may process some data. In November 2025 Digital Ship reported an acquisition of NAPA by the Japanese classification society ClassNK. For a European organisation this means a Finnish headquarters and EU storage, with a reported Japanese owner rather than a US one. NAPA's software is proprietary and not open source.

Why digital sovereignty matters with NAPA

NAPA is headquartered in FI and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

NAPA hosts data in EU, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

NAPA is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs NAPA together with your other vendors and gives a total score, a heatmap and the main risk drivers.
