General
At DIVD the security of our systems is a top priority. No matter how much effort we put into system 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. We would like to ask you to help us protect our systems.
Please do the following
Submit your findings by using the following URL: https://app.zerocopter.com/en/rd/f9afbf32-ce59-48ed-96f2-ac4410595aa4.
What we promise
We will respond to your report within three business days with our evaluation of the report and an expected resolution date. We will keep you informed of the progress towards resolving the problem.
If you have followed the instructions above, we will not take any legal action against you concerning the report.
We will not pass on your personal details to third parties without your permission unless it is necessary to comply with a legal obligation.
In the public information concerning the reported problem, we will give your name as the discoverer of the problem (unless you desire otherwise). Reporting under a pseudonym or anonymously is possible.
We strive to resolve all problems as quickly as possible, and we would like to play an active role in the ultimate publication of the problem after it is resolved.
This Responsible Disclosure policy is based on an example written by Floor Terra and the Responsible Disclosure Guideline of the NCSC.
