A Virtual Private Network (VPN) is a technology that enhances your online security and privacy. When using a commercial VPN service, you connect to a server managed by the VPN provider using an encrypted connection. In other words, all data sent between your computer and the VPN server is encrypted so that no one else can read it.
This setting has a number of important effects that result in a significant increase in Internet security. Since your data is encrypted, all activity is hidden from your Internet Service Provider (ISP). Keep in mind that your VPN provider may see your internet activity, so a VPN should always be seen as a protection for your personal information rather than anonymity. If you are also looking for a VPN then you can choose a service provider such as Vpnacademy to fulfill your security needs.

Also, because your data is encrypted, using a VPN prevents many forms of man-in-the-middle attacks, in which adversaries try to intercept your data along the way. This is especially true when using public WiFi hotspots, which pose a great danger to Internet users. When using a VPN, your information is encrypted even if you are connected to an "Evil Twin" access point.
Your IP address is hidden from the internet because the VPN server acts as a proxy. Therefore, malicious websites and the like can only register the IP address of your VPN server, not your real IP address (a unique number that identifies each connected device). It not only help you protect your personal information online, but it also makes it harder for opponents to attack you. Unluckily, making use of a VPN is a very partial solution here as websites use all kinds of malicious methods to track and solely identify visitors.
