Threat Protection Pro is NordVPN’s ad blocker that’s only available on Windows and macOS. It blocks ads, ad trackers, shady sites, and protects you against malicious downloads. The tool also scans for apps with security flaws on your computer, but this is only available on Windows. One of its biggest advantages is that Threat Protection Pro works even when you’re not connected to the VPN.
Threat Protection is available on iOS, Android, macOS, Windows, and Linux. Unlike Threat Protection Pro, it only blocks ads and malicious websites. Also, in order for Threat Protection to work, you need to be connected to a VPN server — except on Android and iOS, where you can choose whether you want it to only be active when the VPN is connected or always.
