Double VPN and its work
Two VPN servers in order to disguise your location and online activities even more efficiently through encrypting it twice.
VPN server chaining steps.
Your traffic first gets encrypted on your device and is redirected to a remote VPN server afterwards
Once it reaches the VPN server, it gets encrypted once again
The encrypted traffic passes through a second VPN server, where it gets decrypted
You reach the website you wanted to reach, with maximum security and privacy.
