Jeroen is a typical security jack-of-all-trades. He is a hands-on security architect, who loves to secure anything: from (private) clouds, to mobile apps, and anything in between. Jeroen has been involved in various OWASP projects, now focusing on OWASP WrongSecrets.
He enjoys a pentest every now and then, while helping organizations to get secure enough. Jeroen is often engaged in knowledge sharing through talks, blogs, projects at Github, and trainings.
