Security for mobile phones and PCs

For secure protection, you must install the My Security app on your devices and adjust the necessary settings. Once you have placed your order, you will receive an e-mail with the link to download the app.

Use the free Security Checker to check whether your personal data is publicly accessible. The Security Checker runs on F-Secure technology. We do not store the e-mail address or personal information compromised by the data breach. If a data breach is discovered, the analysis result will be sent to the e-mail address provided.

There is still a risk even if you are cautious online. Many threats, such as data leaks, malware and phishing, happen in the background and remain undetected. Comprehensive protection is therefore essential to safeguard personal and confidential data.

Even the most seemingly innocuous information can be misused. Criminals use stolen data for identity theft or to commit fraud or extortion. Data protection thus protects your digital identity and privacy.

A strong password is important, but it does not guarantee comprehensive protection. Additional effective security measures include using password managers, two-factor authentication and running regular software updates.

Phishing is the attempt to obtain confidential information such as passwords or credit card details via fake emails, websites or text messages. These can be deceptively realistic and difficult to spot.

Installation and use of the security app

The following recommendations will minimise your risk in the digital world:

• Use unique, secure passwords
• Use a password manager
• Activate two-factor authentication
• Never open suspicious e-mail links and attachments
• Use VPN in public networks
• Run regular software updates

In public networks, anyone using the same WLAN could, in theory, spy on or intercept your data. Cybercriminals can create bogus hotspots or tamper with your connection. Without protection, your passwords, bank details or private information are vulnerable to snooping. You should therefore use a VPN (Virtual Private Network) to encrypt your connection.

Take immediate action:

• Change affected passwords
• Inform your bank or the service affected
• Run a full security scan
• If in doubt, seek professional support

To protect younger users, it is essential to implement technical safeguards (e.g., to protect them from inappropriate content or limit screen time), clearly explain the risks, and provide supervision and support. We recommend talking to your children regularly, setting age-appropriate rules and taking a generally cautious approach to using digital media. swisscom.ch/campus
