While surfing, you leave traces and companies track your activities for targeted advertising or to collect and sell information about you. The encryption feature is important when you connect to Wi-Fi in a restaurant, cafe, hotel, the airport, or any other public network. This way, your passwords and personal data are safe. Browse anonymously with an active VPN connection to encrypt all the data received and sent and protect yourself from hackers. The reason: other people in this network can access and steal your data.
Surfing online is inherently insecure, especially when connected to a public Wi-Fi network.
