about the hackday

what is the hackday?

HackDay is a cybersecurity challenge open to all students in higher education, created in 2022 by the associative Internet operator OpenGate of the ESIEESPACE association and the company SIFARIS.


Numerous challenges are proposed, allowing the participants to make their neurons boil, in order to reach the flags and to accumulate the most points.


During a whole day, security experts are invited to share their themes and their latest discoveries with an informed public.


If you are looking to identify tomorrow's talent for a future recruitment campaign, then our event is a very relevant solution.
