NordVPN is a Virtual Private Network (VPN) service that provides both security and privacy. It is designed to help users protect their information and online activity from unwanted attention and malicious actors. It does this by creating an encrypted tunnel between a user’s device and the internet, thus hiding the user’s IP address and making it impossible for anyone to monitor their online activity. NordVPN also offers protection from malicious websites, prevents snooping from ISPs, and allows access to geo-restricted content. It also provides a double VPN encryption option for added security, and an automatic kill switch to ensure that no data is leaked even if the connection is unexpectedly dropped. NordVPN is available on a variety of platforms, including Windows, macOS, iOS, and Android.
Open source vs. closed source. Two totally different VPN approaches that cannot be compared from a technical point of view.
