Its mission is to enhance transparency, coordination and the effectiveness of donor support aimed at strengthening Ukraine’s cyber resilience. TMPO was established with the support of EU CyberNet and the Estonian Centre for International Development (ESTDEV).

“Today, Ukraine is facing the most technologically advanced war in history. In addition to the physical destruction caused by missile strikes, the country faces daily waves of cyberattacks targeting critical infrastructure. In this context, support from international partners, both governments and the private sector, is crucial to ensuring the country’s digital resilience. Understanding that such support can only be effective with well-coordinated efforts, the Estonian Ministry of Foreign Affairs initiated the creation of the Tallinn Mechanism,” said Valeriya Ionan,deputy minister for Eurointegration at Ukraine’s Ministry of Digital Transformation.

“Tallinn Mechanism has become a platform uniting the efforts of multiple partner countries in the joint fight against cyber threats and in protecting Ukraine’s digital infrastructure. The opening of the project office in Kyiv is aimed at enhancing coordination among partners and ensuring stable, long-term support for Ukraine’s digital security,” Ionan added.

One of TMPO’s key goals is supporting the Catalog, an online platform that simplifies interaction between donors and Ukrainian institutions. The Catalog allows Ukrainian recipients to submit cybersecurity project proposals, while international donors can select and fund initiatives aligned with their priorities.

“The Tallinn Mechanism is a unique format that allows donors to pool resources, avoid duplication of efforts and support Ukraine where it is most needed. For Estonia, this initiative is not only about cyber assistance, it’s also about building a strong digital coalition around Ukraine,” said Tanel Sepp, Estonia’s Ambassador at Large for Cyber Diplomacy, Director General of the Digital and Cyber Diplomacy Department.

“It is gratifying to see that the initiative initiated by Estonia and our partners has grown immensely in such a short time. As Ukraine’s cyber resilience is more important than ever, the implementation center in Kyiv is a logical step in the development of the Tallinn Mechanism. It provides a clear point of reference for coordinating the initiative and involving even more partners and implementing projects,” said Klen Jäärats, ESDTEV’s executive director.

Background

TMPO will also work to involve the private sector—both Ukrainian and international cyber companies—in implementing Tallinn Mechanism projects. This enables private businesses to contribute to the TM ecosystem, participating in initiatives ranging from threat detection and incident response to capacity-building training for Ukrainian cybersecurity professionals.

The establishment of TMPO was initiated by the Ministry of Digital Transformation of Ukraine. The office will work closely with Ukrainian TM partners, in particular, the State Service of Special Communications and Information Protection (SSSCIP), the Ministry of Foreign Affairs, the Security Service of Ukraine, and the National Cybersecurity Coordination Center (NCCC). This collaboration will help donors provide more targeted and efficient support for cyber projects benefiting TM recipients, including central and local authorities and state-owned critical infrastructure operators.

The Tallinn Mechanism was launched in 2023 as an international response to growing cyber threats and russia’s ongoing aggression. Its mission is to strengthen Ukraine’s cyber defense by making international assistance more effective and coordinated among partner countries. It includes 11 member states: the United Kingdom, Denmark, Estonia, Italy, Canada, the Netherlands, Germany, Poland, the USA, France and Sweden. The European Union and NATO serve as official observers. Currently, France and Estonia are co-chairs of the initiative.

Dozens of initiatives are already being implemented within the TM: cybersecurity assessments, training programmes and the provision of Starlink terminals, which play a vital role in maintaining Ukraine’s digital resilience.

The Tallinn Mechanism and TMPO represent the frameworks and tools for international cooperation, helping Ukraine defend its sovereign rights in cyberspace and adapt to long-term cybersecurity challenges.
