Reporting weaknesses in our IT systems

Nederlands

We work daily to improve our systems and processes. We do this to help our customers safely manage their credit cards online and to keep our systems reliable. If you do find a weakness in one of our IT systems, we would appreciate your help.

Working together

Mistakes can happen, and we don't want to hide them from the public. However, sharing weaknesses in our IT systems without first discussing them with us can have serious consequences, even if your intentions are good. Criminals could misuse your information, for example to commit online fraud. To prevent this, we ask you to work on a solution with us first. This allows us to take measures to prevent system outages and fraud. We are happy to reward you for this.

What can you report?
