Responsible Disclosure

At Previder, we consider the security of our systems very important. Despite our care for the security of our systems, there may still be a weak spot. If you have found a weak spot in one of our systems, we would like to hear about it so that we can take measures as quickly as possible. We would like to work with you to better protect our customers and our systems.

We ask that you:

  • Email your findings to responsible-disclosure@previder.nl or contact our security officer by phone;
  • Do not abuse the problem by, for example, downloading more data than necessary to demonstrate the leak or accessing, deleting or modifying third-party data;
  • Not to share the problem with others until it is fixed and to delete all confidential data obtained through the leak immediately after the leak is fixed;
  • Not to use physical security attacks, social engineering, distributed denial of service, spam or third-party applications;
  • To provide sufficient information to reproduce the problem so that we can fix it as soon as possible. Usually the IP address or URL of the affected system and a description of the vulnerability is sufficient, but more may be required for more complex vulnerabilities.

What we promise:

  • We will respond to your report within 3 days with our assessment of the report and an expected date for resolution;
  • If you have complied with the above conditions, we will not take any legal action against you regarding the report;
  • We will treat your report confidentially and will not share your personal information with third parties without your consent unless necessary to comply with a legal obligation. Reporting under a pseudonym is possible;
  • We will keep you informed of the progress in resolving the problem;
  • In notifying you of the reported problem, we will, if you wish, include your name as the discoverer.
  • We aim to resolve all problems as quickly as possible and we will be happy to be involved in any publication about the problem after it has been resolved.
