Officers
2
Two officers are currently on record for Cyber Security Agency OÜ, filed with Estonian e-Business Register (ariregister). Klaid Magi and Mariell Magi both serve as Juhatuse Liige.
Management authority at Cyber Security Agency OÜ sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
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
Cyber Security Agency OÜ has no recorded parent company — it sits at the top of its own group structure, with 2 subsidiaries recorded beneath it across 1 jurisdiction. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 2 subsidiaries span Estonia jurisdiction, 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.
