Double VPN, also known as a process of chaining the VPN servers, is a technology solution that allows hiding users’ online activity behind several servers via a VPN tunnel. As a matter of fact, the working principle is rather simple: the user connects to the first VPN server, which in turn redirects all the traffic to another server, from where online traffic reaches the final destination. This way, the connection goes through two different servers in various locations: the external IP address is changed, and the traffic is encrypted once, then it gets re-encrypted on the second server in another location.
It means the second VPN server will not be aware of your real IP address since it was changed and hidden by the first server. In addition to this, even though your ISP will know that you are using a VPN service, the final destination on the web will remain hidden. Another important aspect – the connections are mixed between UDP and TCP which also intensifies the security level when you are searching the web. In the end, an extra layer of anonymity and Internet privacy is created, while the online traffic is encrypted not once but twice.
In general, double traffic encryption may not be necessary if you only want to unblock services that are inaccessible in your location, stream video content or access specific media platforms. However, the advanced VPN encryption feature can be extremely useful and even necessary when a high level of online security and anonymity is required. Taking into consideration all the journalist, political activist and bloggers working and living in the countries with authoritarian governments along with the high level of Internet censorship and surveillance.
Despite the many advantages and benefits, double encryption offers in the context of Internet security and privacy, there are only a few service providers that support the Double VPN technology. Therefore, we at NordVPN apply advanced encryption principle by using remote servers to create VPN chain and increase our users’ online privacy and anonymity.
Thus, to accommodate those needs and to make VPN experience as secure as possible, we at NordVPN offer the double encryption feature for all our clients with no extra charge. In addition to this, we currently offer several Double VPN combinations, including US-Canada, UK-Netherlands and Taiwan-Hong Kong.

Also, it is important to mention that advanced security features may slow down your Internet speed due to the multiple layers of encryption. However, in some cases, the link between the VPN servers is highly optimized – this way the time lost due to decryption/encryption can be simply compensated. Nonetheless, advanced VPN encryption is advisable and even highly required when a high level of anonymity and online privacy is necessary due to censorship and strict Internet regulations.
