Severity assessment

This program follows Intigriti's contextual CVSS standard


How should we create an account?

When creating an account, you have to provide first name and last name: "Intigriti" and "Test". The email address must be your email address.

How to create multiple applications?

In the field 'Rental period' you can choose:
1st semester
2nd semester
Whole academic year.
Never select 'Whole academic year'. If you select '1st semester' and save the request, you can create a second request by selecting '2nd semester'. If you want to create subsequent requests, please contact Intigriti. They will convey your question to KU Leuven.

All aboard!
Please log in or sign up on the platform

For obvious reasons we can only allow submissions or applications for our program with a valid Intigriti account.

It will only take 2 minutes to create a new one or even less to log in with an existing account, so don't hesitate and let's get started. We would be thrilled to have you as part of our community.
