The investigation conducted by the CNIL on the Sergic website showed that any user could access documents and files stored by other users in their personal spaces, by slightly changing the URL address displayed in the browser.

The CNIL's recently published activity report states that the CNIL received 1,170 data breach notifications in 2018, compared to approximately 100 notifications in 2017.
