I am a Security Analyst at Zerocopter, where I identify and validate a variety of vulnerabilities and security issues on a daily basis.
Next to my day-job I'm a volunteer with the Dutch Institute for Vulnerability Disclosure (DIVD), I contribute to coordinated vulnerability disclosure. At DIVD, I head the CSIRT, ensuring that operations run smoothly and are well-structured. My work has involved notable cases, including high-profile incidents such as the July 2021 ransomware incident involving Kaseya. I have also discovered vulnerabilities for several large organizations, including the Dutch government.
In addition to my work at DIVD, I am a founder and board member of CSIRT.global, an organization dedicated to building an international community and improving global cybersecurity. I have been volunteering with Hack in the Box (HITB) since 2018, contributing to the success of their security conferences. This year, I am also volunteering to help organize the very first edition of Orangecon, a new security conference in the Netherlands.
