Forms to report a data breach

Everything you report will become an official document. This means that anyone can request access to the document, and the document might have to be disclosed depending on the outcome of an assessment of whether secrecy applies. The decision whether a document can be disclosed or not is always ultimately made by the Swedish Authority for Privacy Protection.

Therefore, we recommend that you only reply to the questions asked, not providing more information than necessary using the free text fields. Should you nevertheless choose to provide what you consider is confidential information, the free text field at the end of the form should be used to describe which information this applies to.
