What happened
Ukraine has been granted access to the European Union’s Cybersecurity Reserve, allowing the country to request emergency cybersecurity assistance during major cyberattacks that exceed its own response capabilities.
The European Commission announced that EU member states approved Ukraine’s participation in the reserve, which is managed by the European Union Agency for Cybersecurity (ENISA). The reserve consists of pre-approved private cybersecurity companies that can be rapidly deployed to assist governments and critical infrastructure operators during significant cyber incidents.
The Cybersecurity Reserve was created to provide incident response services, digital forensics expertise, technical support, and recovery assistance to participating countries facing large-scale cyberattacks.
Under the arrangement, Ukraine can formally request assistance when an incident surpasses the capacity of its national cyber response teams. Support may include digital forensics, incident containment, recovery operations, cyberthreat intelligence sharing, and post-incident security improvements.
Ukraine becomes the second non-EU country granted access to the reserve after Moldova, which joined the program in 2025 amid increasing cyber threats linked to Russia.
Ukrainian officials described the move as both a practical cybersecurity measure and a sign of deeper integration with European security structures as the country continues its path toward EU membership.
Who is affected
Ukrainian government agencies, critical infrastructure operators, and organizations responsible for national cybersecurity stand to benefit directly from access to the reserve.
The arrangement is particularly relevant given Ukraine’s continued exposure to cyberattacks targeting government institutions, critical services, and national infrastructure during the ongoing conflict with Russia.
EU member states and participating cybersecurity providers are also affected because they may contribute expertise, incident response services, and technical resources during major cyber incidents impacting Ukraine.
Why CISOs should care
The decision highlights the growing importance of collective cyber defense models. Rather than relying solely on national capabilities, governments are increasingly building mechanisms that allow trusted partners to provide surge capacity during large-scale cyber incidents.
For CISOs, the Cybersecurity Reserve represents an example of how cybersecurity resilience is evolving beyond traditional organizational boundaries. Large incidents often require specialized expertise, forensic resources, and recovery capabilities that may not be available internally during a crisis.
The move also reflects the strategic role cyber cooperation now plays in broader security and geopolitical partnerships. As cyber threats become more sophisticated and state-linked activity continues to increase, organizations may see greater emphasis on cross-border threat intelligence sharing, coordinated incident response, and mutual assistance frameworks.
Ukraine’s inclusion further demonstrates how operational cybersecurity experience can become a strategic asset. Years of defending against advanced cyber campaigns have enabled Ukrainian organizations to contribute threat intelligence and expertise alongside receiving assistance from European partners.
3 practical actions
- Develop external incident response partnerships before a crisis occurs: The Cybersecurity Reserve provides access to specialized expertise during major incidents. Organizations should establish relationships with trusted incident response providers and external partners before they are needed.
- Build procedures for rapid escalation during large-scale attacks: Ukraine will be able to request assistance when incidents exceed national capabilities. CISOs should define clear thresholds for when external support, forensic specialists, or recovery partners should be engaged during major incidents.
- Strengthen threat intelligence sharing programs: The reserve emphasizes collaboration and intelligence exchange among trusted partners. Organizations should participate in industry information-sharing groups and establish processes for consuming and sharing actionable threat intelligence.
