About HALON
HALON (Hack All Education in the Netherlands) is a hacking event for education, by education. With your team, you will search for vulnerabilities in the open IP ranges and a number of domain names of various Dutch educational institutions. By finding vulnerabilities, you also contribute to the cyber resilience of these institutions. The organisation is in the hands of SURF, the IT partnership for education and research. We ensure proper handling of found vulnerabilities.
Who is it for?
HALON is intended for students and employees of universities, universities of applied sciences and mbo's. It is useful if you already know your way around IT systems, but you are also welcome if you are not so experienced.
