NordVPN provides several security features
Double data encryption
This is a dual encryption system deployed by NordVPN to safeguard incoming and outgoing data, utilizing AES-256-CBC encryption. This kind of encryption is considered military-grade and is applied twice to increase security levels.
Automatic kill switch
NordVPN provides a kill-switch feature, this helps users remain safe even if their connection is interrupted, as all location-sensitive apps are locked down when a temporary disconnect occurs. This feature is very popular among gamers and file-sharing services.
DNS leak resolver
DNS servers are known to have security risks because they are able to transmit queries that are not encrypted, enabling external entities to access sensitive information, such as your IP address and the websites you’ve visited. You won’t even realize that such data has been sent. NordVPN prohibits this from occurring by guaranteeing that all of your DNS queries are secure when you’re connected to the service.
Strict no-logs policy
NordVPN has a strict no-logs policy, therefore your activities on its servers is never logged in any way. NordVPN uses a Tor over VPN solution to send encrypted traffic over the Tor network. Traffic is always encrypted as it jumps to different locations worldwide to make it almost impossible to trace.
