At World CISO Day the security of our systems is top priority. No matter how much effort we put into our security, there might 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 protect our clients and our systems.

Please do the following:

• Submit your findings by using this URL.
• Report the vulnerability as quickly as is reasonably possible, to minimise the risk of hostile actors finding it and taking advantage of it.
• Report in a manner that safeguards the confidentiality of the report so that others do not gain access to the information.
• Provide sufficient information to reproduce the problem, so we will be able to resolve it. 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.

Please don't do the following

• Reveal the vulnerability or problem to others until it has been resolved.
• 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.
• Build your own backdoor in an information system with the intention of then using it to demonstrate the vulnerability, because doing so can cause additional damage and create unnecessary security risks.
• Use brute force attacks, attacks on physical security, social engineering, distributed denial of service, spam or applications of third parties to gain access to the system.
• Repeatedly gain access to the system or share access with others.

What we promise

• We will respond to your report within five 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 concerning the report.
• We will handle your report with strict confidentiality, and not pass on your personal details to third parties without your permission, unless it is necessary to comply with a legal obligation. Reporting under a pseudonym or anonymous is possible.
• We will keep you informed of the progress towards resolving the problem.
• In the public information concerning the reported problem, we will give your name as the discoverer of the problem (unless you desire otherwise).
• As thanks for your help, we offer a reward for every report of a vulnerability that was not yet known to us. The reward will be determined based on the severity of the vulnerability and the quality of the report.

We strive to resolve all problems as quickly as possible, and we would like to play an active role in the ultimate publication on the problem after it is resolved.


This Coordinated Vulnerability Disclosure policy is based on an example written by Floor Terra on responsibledisclosure.nl and the Coordinated Vulnerability Disclosure Guideline of the NCSC.
