Ministry of Digital Transformation of Ukraine, posted 22 December 2025 17:17

In two years of operation, the Tallinn Mechanism has become a key tool for coordinating international assistance in the field of cybersecurity in Ukraine. The initiative has brought together 13 partner countries and attracted EUR 241.7 million in international funding for projects to strengthen cyber resilience, protect digital sovereignty and critical infrastructure.

The Tallinn Mechanism began operating on 20 December 2023 in response to long-term cybersecurity challenges in the context of full-scale war.

"The world's first cyberwar is ongoing in Ukraine, and we are developing new approaches to cyber resilience. Every day, Ukraine finds effective solutions and sets the pace in countering digital threats. That is why the support of our partners is critically important to us. The Tallinn Mechanism is about trust between states, quick decisions, and systemic support. Such a partnership allows us to respond quickly to challenges and work together to build a secure digital environment — for Ukraine and the entire democratic world," said Valeria Ionan, Advisor to the First Deputy Prime Minister — Minister of Digital Transformation of Ukraine on Innovation, Digitalisation and Global Partnerships.

Key results over two years:

  • EUR 241.7 million in international aid has been raised for cybersecurity projects, including EUR 60.9 million in 2025;
  • 13 countries have joined the initiative, with the European Union, NATO and the World Bank participating as official observers;
  • cybersecurity and cyber risks have been assessed for approximately 30 critical infrastructure facilities;
  • a transparent system for selecting and coordinating cyber assistance projects has been established;
  • measures are being implemented to develop human resources in the field of cybersecurity.

Coordination of international cyber assistance

During the operation of the Tallinn Mechanism in Ukraine, a transparent system for selecting and coordinating cyber assistance projects has been established, ensuring coordination between the state and international partners.

The Tallinn Mechanism includes:

A technical working group that evaluates projects for technical feasibility and compliance with priorities.

An interdepartmental working group chaired by First Deputy Prime Minister and Minister of Digital Transformation of Ukraine Mykhailo Fedorov, which determines the strategic importance of initiatives.

To ensure transparency and centralised interaction with donors and recipients, the Tallinn Mechanism Project Office (TMPO) was established. It acts as a permanent coordination centre between international partners and Ukrainian institutions, supports project implementation and ensures coordination between all parties. The TMPO was established with the assistance of ESTDEV and EU CyberNet. The office works closely with the State Service of Special Communications and Information Protection, the Ministry of Foreign Affairs, the Security Service of Ukraine, and the National Cyber Security Centre.

A catalogue has also been launched — a cyber assistance portal for project verification and selection.

The implementation of projects for the Secretariat of the Cabinet of Ministers, the National Health Service, the Ministry for Veterans Affairs, the Ministry of Economy, Environment and Agriculture, the State Enterprise ‘Diia’, ‘Ukrenergo’ and the State Customs Service has begun. Cooperation has also been initiated with the State Judicial Administration, the Chernobyl Nuclear Power Plant, the State Border Guard Service, the National Cybersecurity Coordination Centre, the State Service of Special Communications and Information Protection, the State Migration Service, the Ministry of Foreign Affairs, the Office of the Prosecutor General, Ukrzaliznytsia, and Ukrposhta. A separate area of work is regional support. Two projects are being implemented in the Ternopil region within the framework of the Tallinn Mechanism.

Expansion of international partnership

The Tallinn Mechanism is constantly expanding its circle of participants and partners. To date, 13 countries have joined the initiative (the United Kingdom, Denmark, Estonia, Italy, Canada, the Netherlands, Germany, Norway, Poland, the United States, France, Sweden and Finland), while the European Union, NATO and the World Bank participate as official observers. The United Kingdom currently leads the mechanism. The next meeting of donor countries will take place in March in London.

In addition, the mechanism is moving towards more active interaction with the private sector. The Tallinn Mechanism Project Office (TMPO) team is working on the creation of the Tallinn Mechanism Platform, a digital platform that will launch in early 2026 and expand opportunities for businesses to participate in joint cyber initiatives, in particular through access to information on tenders and projects.

Human resource development

The Tallinn Mechanism systematically supports the development of human capital in the field of cybersecurity. With the participation of international partners, training programmes and educational events are being implemented for civil servants and cybersecurity specialists.

In particular, a series of training programmes has been launched at the CDTO Campus with the support of France (in cooperation with Expertise France) and Germany (in cooperation with Monarch). The NCCK, the Estonian Embassy and the Estonian Centre for International Development (ESTDEV) have also launched the UA-EE Cyber Shield via Tallinn Mechanism exercises in Kyiv.
