Responsible disclosure in English

Hackers may discover (in an ethically responsible manner) and report vulnerabilities in our IT-security. Should you discover a vulnerability, we would like to hear from you, in order to take steps to address the issue as soon as possible. This helps us learn and avoid damage as a result of malicious action. If you, as an ethical hacker, abide the stated rules, we will not pursue legal action against you regarding your report to us.

What we ask
  • Email your findings to cert@deltion.nl in a safe manner.
  • Do not take advantage of the vulnerability you found.
  • Do not reveal the problem you found to others.

What we promise
  • We will not take legal action against you.
  • We will respond within five workdays.
  • We will handle your report with strict confidentiality.
  • We will keep you informed of the progress towards resolving the problem.
  • At your request we will mention you in our online Hall of Fame.
  • Deltion does not reward trivial vulnerabilities (known and accepted vulnerabilities and risks) or bugs that cannot be abused.
