A VPN protects your internet connection from being intercepted or tampered with. It works by encrypting all traffic between your PC and the internet. In addition, it allows you to connect to multiple devices at the same time. This type of protection is essential if you want to protect more than one device. The software on a VPN server serves as a proxy. This means that websites will only see your IP address and location when you are connected to the VPN. Another advantage of a VPN is that it enables you to access more content. The encryption tunneling technique is effective in overcoming geoblocking restrictions and government censorship.

NordVPN is one of the few VPNs available on Android. Although the company does not provide an APK file, it is available on Google Play. The app offers many locations and is free to download. The split tunneling feature lets you decide which sites you wish to protect and which you don't. Users can also enable ad blocking and malware blockers to further enhance their privacy. There is no need to download any software, and it's simple to use.

A VPN should also come with a kill switch. It prevents unencrypted data from leaving your device. The kill switch is a feature of many VPNs that automatically cuts off your Internet connection if the connection is lost. When it's active, the kill switch will prevent your device from accidentally exposing your IP address to the Internet. While it's good to use a VPN when you're connected to public Wi-Fi, you'll be more likely to be in a situation where the connection is dropped.
