The safety of your data is our top priority. That’s why we work hard to protect our systems. But did you nonetheless find a flaw in our security? Help us by reporting the vulnerability. Please do not make a vulnerability public, before working with us on a solution first. We are not trying to cover up our mistakes, but making a vulnerability public might have serious consequences for all our customers.
You can report a vulnerability by sending an email to email@example.com. If possible, encrypt your email with our GPG-key (ask for key) to prevent the information from falling in the wrong hands. Please explain in your e-mail the vulnerability you have found and provide us with enough information to reproduce and investigate the problem.
Absolutely. You are not required to provide your personal details.
Reports related to DMARC or SPF are not needed. We are aware of the issues.
You might have conducted illegal activities to discover a vulnerability. We will not report these activities or claim damages if you have followed these rules:
We will start an investigation immediately after receiving your report. We always try to get back to you within a couple of days and will keep you up-to-date about our progress on solving the problem. The time we need to solve an issue depends on the complexity of the problem. After you have reported a problem, we ask you to refrain from making it public to give us time to solve the issue first.
Together, we can decide if and how the issue will be made public (after the problem has been solved). We can include your name in the publication if you want.
To thank you for your help we may offer you a reward, but we are never required to offer a reward. We only offer rewards for flaws that were unknown to us at the moment of reporting. We will determine the type and size of the reward based on the reported issue, taking the severity of the issue (amongst other things) into account. In case multiple people report the same issue, we will only offer a reward to the first reporter.
We only use your personal details to take action in response to your report. We don't share your data with third parties without your permission, unless we are legally required or a court order requires us to do so. If we contract another company to investigate your report, we might be required to share your data with this company. We will ensure this company also keeps your data confidential.
Always take applicable laws and regulations into account, because you could still get in trouble with the law, even if we don't report you to the authorities.
