We aim to make the digital world safer by reporting vulnerabilities we find in digital systems to the people who can fix them. We have a global reach, but do it Dutch style: open, honest, collaborative, and for free.

Ethics at the base of everything we do

Since we handle sensitive data collected without informed consent, we've created this Code of Conduct to establish an ethical foundation for our work. This code can also be utilized by other researchers involved in what is currently known as responsible disclosure or coordinated vulnerability disclosure.
