Find out whether your personal information has been made publicly available with the free Security Checker. The Security Checker runs on F-Secure technology.

Terms and conditions of use

When you press ‘Send Report’, your e-mail address will be transmitted to F-Secure, which will perform the relevant analysis. If a data breach is detected, the analysis result will be sent to the specified e-mail address. Swisscom and F-Secure do not store your e-mail address or the information gleaned as a result of the data breaches and do not accept any liability for incorrect information.

The Security Checker examines the material from data breaches for accounts that are linked to the e-mail address provided by you. 

A data breach occurs when your personal information is made public by a company or organisation. This includes particulars such as passwords, telephone numbers and date of birth. 

If your data has been misused, you will receive an e-mail with the details and possible measures you can take to prevent further misuse. 

You can check multiple e-mail addresses step by step. If a data breach is found to have occurred, you will receive separate information and appropriate instructions on how to proceed for each e-mail address checked.
