Both novice entrants into the world of VPN and experienced online security specialists will likely have heard the phrase “Double VPN”. It is a security measure that not a lot of VPN companies offer, and the small number that do so ensure that they include it in their best features list.
Double VPN, sometimes called multi-hop, is the procedure of stringing together two VPN servers. This is a hi-tech solution that permits hiding online activities behind a number of servers and VPN tunnels. The working rationale is quite straightforward: you connect to the primary VPN server, which in line forwards all the traffic to another server, from which point the online traffic gets to the final destination. The connection goes through two distinct servers in different places: the external IP address is altered, and the traffic is encoded once, and afterwards, it gets encrypted again by a second server in a different spot.
How does double VPN work?
It would not be shocking to suppose that some individuals think the phrase “double encryption” means the usual encryption level, which is AES 256-bit would then be converted into AES-512 – that’s not the case.
To illustrate the double VPN meaning in a better way, imagine you have a functioning VPN connection that is routed via an encrypted channel to a server in a country of your preference. The standard form of encryption in effect would be that of the AES-256 bit. With an attribute such as double VPN brought into the mix, traffic from the first server will get re-routed to the second one that is not necessarily based in the same location.
This would cause the data to be encrypted again, adding to the complexity and making it harder for a third party to decrypt. This also leads to a very high anonymity level, as it makes the task of straightforwardly tracking back to the point where the connection was initiated very difficult.
The advantages of Double VPN
On the whole, double encryption might not be essential if you only need safe access to censored content, media platforms or streaming sites.
Although the sophisticated VPN encryption can be enormously helpful and even indispensable when advanced online security and privacy is required. This is particularly pertinent to all the political activists, bloggers and journalists living and working in countries with dictatorial regimes that have a soaring level of Internet surveillance and censorship.
Fortunately, by employing double VPN, one can create an additional layer of confidentiality, which adheres to these principles:
- The web traffic is encrypted two times.
- Even if your ISP is aware that you are using a VPN, the ultimate browsing destination will stay unknown.
- The connections can be jumbled between TCP and UDP, which also enhances the level of security when you are surfing the web.
Double VPN disadvantages
There are various drawbacks, as well. Among them is that this is not something many individuals generally look for when they are buying a VPN for merely accessing geo-blocked services or websites. The main reason is a significant speed reduction.
It is not a secret that the tougher the encryption, the more sluggish your connection speed will be. Thus, if you want to watch or stream a show on the web, a double VPN may not be of much aid. Of course, this strongly relies on your individual ISP-given connection speed: people with higher speeds might not even notice the default encryption effects, while those users with slower, more limited bandwidths might struggle streaming anything.
However, a double VPN encryption will severely affect any type of connection, which might turn a trouble-free Internet search into an annoying process. High-grade providers sometimes have multihop as an addition to their default connections, thus making it possible to shift from a double VPN connection to a simple one when the requirement arises.
Conclusion on double VPN meaning and function
Employing a double VPN will, without a doubt, make it extremely unlikely that anyone can get to your data. However, the catch is that it can really slow down the connection. This makes such a connection a resort of complete necessity. In addition, before subscribing to a provider that offers double VPN, it would be best to make sure that the connection is sufficiently fast by default, so it does not hold you back to the point that it becomes annoying.
