Responsible Disclosure


We have decided to temporarily suspend the bug bounty program to catch up on the backlog of reports and prioritize other improvements on our roadmap. We will update this message when the bounty program is open to new submissions again.


At the Hyperstack Corporation, we consider the security of our systems a top priority. But no matter how much effort we put into system security, there can still be vulnerabilities present.

If you discover a vulnerability, we would like to know about it so we can take steps to address it as quickly as possible. We would like to ask you to help us better protect our clients and our systems.

Please do the following:

  • E-mail your findings to [email protected]
  • Do not take advantage of the vulnerability or problem you have discovered, for example by downloading more data than necessary to demonstrate the vulnerability or deleting or modifying other people's data,
  • Do not reveal the problem to others until it has been resolved,
  • Do not use attacks on physical security, social engineering, distributed denial of service, spam or applications of third parties, and
  • Do provide sufficient information to reproduce the problem, so we will be able to resolve it as quickly as possible. Usually, the IP address or the URL of the affected system and a description of the vulnerability will be sufficient, but complex vulnerabilities may require further explanation.

What we promise:

  • We will respond to your report within 3 business days with our evaluation of the report and an expected resolution date,
  • If you have followed the instructions above, we will not take any legal action against you in regard to the report,
  • We will handle your report with strict confidentiality, and not pass on your personal details to third parties without your permission,
  • We will keep you informed of the progress towards resolving the problem,
  • In the public information concerning the problem reported, we will give your name as the discoverer of the problem (unless you desire otherwise), and
  • As a token of our gratitude for your assistance, Critical & High severity valid bug reporters will be listed on Hyperstack's wall of Fame. Of course, we will need to know if you want the recognition, in which case you will be required to give us your name and Twitter handle, LinkedIn Profile as you wish it to be displayed on our Hall of Fame page.
  • We currently do not offer any monetary compensation. However, we may send out Hyperstack swag in some cases.
  • Requests or demands for monetary compensation in connection with any identified or alleged vulnerability are non-compliant with this Responsible Disclosure Policy.
