NordVPN routes all users' internet traffic through a remote server run by the service, thereby hiding their IP address and encrypting all incoming and outgoing data.
For encryption, NordVPN uses the OpenVPN and Internet Key Exchange v2/IPsec technologies in its applications.
Besides general-use VPN servers, the provider offers servers for specific purposes, including P2P sharing, double encryption, and connection to the Tor anonymity network.
NordVPN offers three subscription plans: monthly, yearly and bi-yearly. It is not possible to cancel a subscription through the web interface.
