As a CERT, handling a bug bounty program for your constituents may be challenging. In CERT-EU, during our vulnerability management process, we created a specific page on our website to thanks a researcher pointing out vulnerabilities on our constituents websites.Once the program started, a lot of unexpected issues were encountered and we had to modify our processes and tools to be able to face those challenges.In this presentation we will provide details on challenges and how we handled them to make our life easier and provide a better service for our constituents.
