When you navigate social networks or use online payment service providers, you inevitably have to provide personal information.  But no one can guarantee comprehensive data protection on the internet. After all, history shows that providers do not always handle your data with confidence, such as in the Facebook data leaks and Klarna data leaks in 2021. If you want to protect your data on the internet, you have to: Change your surfing behavior by not visiting dubious websites under any circumstances. Always use a VPN server if possible. Scan your devices for malware regularly. Use strong passwords. Set up two-factor authentication. Encrypt sensitive data.
