Threat Protection is NordVPN’s ad blocker that’s only available on Windows and macOS. It blocks ads, ad trackers, shady sites, and also protects you against malicious downloads. One of its biggest advantages is that Threat Protection works even when you’re not connected to the VPN.
Threat Protection Lite is available on iOS, Android, macOS, Windows, and Linux. Unlike Threat Protection, it only blocks ads and malicious websites. Also, in order for Threat Protection Lite to work, you need to be connected to a VPN server.
