The National Bank of Ukraine (NBU) has signed a Memorandum of Understanding with Mastercard to deepen cooperation on cybersecurity, with the stated aim of strengthening the cyber resilience of Ukraine’s financial sector. Senior NBU and Mastercard executives met to discuss priority areas for implementing the cooperation. The cooperation is intended to develop joint initiatives to promote cybersecurity best practices across the Ukrainian financial sector, exchange data and analytical insights on current cyber threats to improve risk assessment and inform cybersecurity projects, and build cybersecurity competencies including threat prevention, cyber incident response, and safe digital practices. The NBU and Mastercard framed the arrangement as supporting the implementation of international cyber protection standards, innovation, and further digitalization of financial services, and linked it to Mastercard’s broader Digital Country Partnership program in Ukraine referenced in a November 2025 memorandum with the Ukrainian government.
