We have a positive attitude toward the concept of ethical hacking and appreciate it if vulnerabilities in our software are found in a responsible way. If you have found a vulnerability in oue of our systems, we would like to hear about it so that we can solve this as quickly as possible. We would like to work with you to better protect our customers and our systems.

  • Not use attacks on physical security, social engineering, (distributed) denial of services, spam, or third party applications.
  • Provide sufficient information to reproduce the problem so that we can resolve it as quickly as possible. Usually, the IP address or the URL of the affected system and a description of the vulnerability is sufficient, but with more complex vulnerabilities, more information may be necessary.
