Coordinated Vulnerability Disclosure

At Conclusion, we are committed to keeping our systems, network and product(s) secure. Despite the measures we take, the presence of vulnerabilities will always be possible. When such vulnerabilities are found, we’d like to learn of them as soon as possible, allowing us to take swift action to improve our security.

Conclusion kindly request you to:

  • Submit your findings through the 'Coordinated Vulnerability Disclosure report' option in this online form as soon as possible;
  • Provide us with adequate information to enable us to investigate the vulnerability properly. We need to be able to efficiently reproduce your actions; at least an IP/URL and a description of the vulnerability;
  • Provide us with enough information to contact you; i.e. telephone number or email address;
  • Refrain from sharing your observations with others until the vulnerability has been solved;
  • Act responsibly with your knowledge on the vulnerability; do not perform any actions that go beyond what is necessary to demonstrate the flaw.

Always avoid to:

  • Use denial-of-service, social engineering or any other interruption of our services;
  • Copy, change or delete our data;
  • Make changes to a system;
  • Install malware;
  • Use “brute force” techniques

What to expect from us:

  • If you comply with the conditions above, following your report Conclusion will not pursue legal action towards you;
  • Conclusion will confirm the receipt of your report within 72 hours;
  • You will receive our technical appraisal of your report within 30 days and subsequently instruct you on the ‘black out period’ required to deal with the vulnerability if required. During this period the information may not be shared by you with others’;
  • Conclusion will handle your report as ‘confidential’, respecting your privacy unless we are legally required to disclose information to authorities;
  • Conclusion offers you a token of appreciation for your efforts in working with us to improve cybersecurity. As a reference you will find some examples of our ‘bounty assessment criteria’ below.

report, considering potential impact in the relevant context. Their assessment is not open for debate. We will only reward the first reporter of a vulnerability; duplicate reports will not be rewarded.
