Withsecure Oyj
Withsecure Oyj is a Private limited company (Ltd.) registered in Finland under 07055792, and its current status with Finnish Patent and Registration Office (PRH) is active. The company was incorporated on 1 July 1988 and lists its registered address as Helsinki, Finland. 5 shareholders are on record for Withsecure Oyj, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Finnish Patent and Registration Office (PRH) and was last updated on 24 September 2026.

Shareholders

Shareholders of Withsecure Oyj
Five shareholders are currently on record for Withsecure Oyj, reflecting the osakasluettelo (shareholder register) maintained under Chapter 3 of the Companies Act (osakeyhtiölaki) rather than a public filing. The largest of these is DFA Continental Small Company Series, holding 24.2% — the largest recorded stake — followed by ETF Managers Tr-EFTMG Prime Cyber Security ETF at 21.3%; the remaining 3 shareholders shown hold smaller stakes. Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.

Group Structure
Group structure of Withsecure Oyj
Withsecure Oyj has no recorded parent company — it sits at the top of its own group structure, with 13 subsidiaries recorded beneath it across 13 jurisdictions.

Data availability
Those 13 subsidiaries span Finland, Italy, Netherlands, United Kingdom, Germany, Denmark, and 7 more jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Two of the 13 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
