Who we are
The Tallinn Mechanism is an international initiative launched in 2023 to coordinate and systematize cybersecurity assistance to Ukraine. It brings together member states, international organizations, and Ukrainian institutions to strengthen Ukraine’s cybersecurity, and build civilian cyber capacity through coordination of international support. Guided by the principle “Nothing about Ukraine without Ukraine,” all assistance is developed in close collaboration with Ukrainian governmental counterparts. This ensures that aid is both relevant and effective, addressing immediate vulnerabilities while building the foundation for long-term resilience.
