About the team

Join a team that combines cybersecurity, technology, and business strategy. Subsidiary Security is responsible for helping newly acquired companies securely become part of Mastercard. From assessing security risks and emerging technologies to helping shape integration roadmaps, interns gain hands-on experience solving real-world challenges that have direct business impact.
