What is VPN and how it works?


Normally, if you want to browse the Internet, first you need to connect to your Internet Service Provider (ISP), which then forwards you to the desired website or other Internet resource. It means, all your Internet traffic goes through and can be viewed by your ISP.

A Virtual Private Network (VPN) allows you to connect to the Internet via a remote server run by a VPN service provider. All the data traveling from your computer, tablet or phone is transferred via an encrypted connection, also known as a VPN tunnel. That means all the traffic coming from your device is encrypted, so that it is no longer visible to your Internet Service Provider (ISP).



How secure and reliable is NordVPN?


NordVPN uses AES (Advanced Encryption Standard) with 256 bit-keys. In fact, it was used by the U.S. government to secure classified information and by the NSA to protect national security data, before it became the most frequently used algorithm in symmetric key cryptography. Now it is an ideal option for software applications, hardware, and firmware that require either high throughput or low latency.

Furthermore, NordVPN recommends two different security protocols that provide strong VPN encryption between your device and the server you have connected to. Usually, when you connect to one of the NordVPN apps, it automatically selects the encryption settings most suitable for your speed and security circumstances.

Here you will find more detailed information about each security protocol and NordVPN recommendations for choosing between different VPN encryption types.
