The Truth About Double VPN, Triple VPN, and Quad VPN

Currently, VPN technologies are widespread on the Internet. But why, then, the services of Double VPN (or as it is also called dual VPN), Triple VPN, Quad VPN offer only a few services around the world?

Do these technologies really provide protection to their users? Or is the anonymity of these technologies just another myth?

Let's try to figure it out.


Where did Double VPN, Triple and Quad come from
It is not known who first made the cascade of 2 VPN servers. Most likely, the sequential chain of 2 proxy servers can be considered the parent of Double VPN.

Further, the idea received material feedback from clients of VPN services. Many began to believe that finally found a technology that solves absolutely all security problems. Double VPN technology has begun to gain popularity.

If something works and attracts customers, why not create “new technologies”?

Thus, VPN services created Triple and Quad VPN, the idea came up of instantly switching servers on the fly and the ability to change exit points.

In fact, sequential cascading has serious disadvantages. We will talk about them later, but for now, let's continue to watch how Octuple VPN will be created (8 consecutive VPN servers


The essence of the idea of cascading VPN servers
The idea of sequentially transferring traffic between VPN servers is simple.

A connection is created between the user's computer and the first VPN server. Next, a second encrypted channel is created between the first and second VPN server. Traffic is encrypted as if twice and sequentially.

Undoubtedly, this technology has its advantages. Let's take them apart.


Pluses of Double VPN, Triple VPN, Quad VPN
Thanks to this technology, we increase our anonymity. Traffic passes through several servers and is encrypted. At the same time, your external IP address changes several times.

The following advantages of using Double VPN technology can be highlighted:

• your ISP will see a connection to the first VPN server, but will not know your final IP address on the Internet, since Internet access is from a second VPN server
• the second VPN server will not know your real IP address, as it will be hidden by the first VPN server. It enhances your anonymity.
• You can use different geographical locations of VPN servers located on different continents (for example, Panama, Malaysia, Korea).
• at each stage, the IP address changes, which creates the layering of your anonymity

When Double VPN first appeared, many decided it was a great way to anonymize. But we will always talk about an integrated approach to security. And one consecutive VPN is not enough to provide the highest level of anonymity.

But the question is why so few services offer such services if they help solve the issue of anonymity on the Internet?


Why do so few services offer Double VPN?
If you analyze sites for Double VPN on Google, then these services provide just over 10 services worldwide.

If Double VPN has so many advantages, then why do not all VPN series offer such services?

In fact, most services are officially registered as a company, they have real offices.

Companies provide VPN services for customers who just need to change their geographic location to unlock access to services such as Skype, Facebook, Google Disk.

The companies have a real office where you can send an official request. Anonymity of clients for such companies is not important, and such services will immediately provide all the data to the client at the first request from the police.

As a rule, registered companies are required to keep logs and record the actions of their customers in accordance with the law. We have compiled a list of questions by which you can definitely find out if the VPN service keeps logs.

It makes no sense for companies to complicate the sales model by introducing Double VPN. Because along with this it is also necessary to develop a system for logging the actions of clients using a cascade of servers.

Double VPN enhances anonymity, but is there any danger in using it?


Why is Double, Triple, Quad VPN dangerous?
The technology of sequential cascading of VPN servers involves the presence of consecutive encrypted channels.

But then the main question arises, but what is between the channels?

At each step, the information is decrypted and then re-encrypted, leaving the next channel. Thus, at each stage, traffic is encrypted and decrypted. Roughly speaking, this process takes place in RAM and practically does not pose a great danger.

But in April 2014, a vulnerability was found in the OpenSSL package HeartBleed, due to which it became possible to remotely read the contents of the memory. This error in OpenSSL code has existed since 2011. And we cannot say for sure whether she appeared by chance or not.

Therefore, such decryption of traffic on each server carries a great danger to clients.

Let's highlight the disadvantages of using Double, Triple and Quad VPN.


Cons of Double VPN, Triple VPN and Quad VPN
Despite all the advantages of the sequential cascading technology of VPN servers, we can highlight the disadvantages of using this technology.

The main disadvantage is the decryption of traffic on each VPN server. We have already noted this dangerous step in terms of your anonymity.

The second disadvantage of this technology is a noticeable drop in speed when using chains of VPN servers. This is due to traffic encryption, geographical distance between servers.

We tested the drop in speed between using a regular VPN and Double VPN. You need to test the same exit points (same servers). All results are indicative, since if you conduct several tests in a row, the data can vary greatly (at times).

First, the speed of a standard VPN connection was checked. In this case, the traffic goes to a server in the Netherlands. Then go to speedtest.net, located in the USA. And it returns to your computer in the reverse order.

Checking the speed of a Double VPN connection. Traffic goes from your computer to a server in Germany, then to a server in Holland. After that, traffic goes to the Speedtest site located in the USA. To display data, traffic is returned to your computer in the reverse order.

Check speed offshore Double VPN connection. Please note that in this case the traffic goes from your geographical location to the offshore VPN server in Panama, then to the server in the Netherlands and then comes to the Speedtest website (which is located in the USA). Then the data from the site comes to your computer in the reverse order.

If you use Triple VPN and Quad VPN chains, the drop in speed may be even greater. Accordingly, using such chains will not be comfortable.

If this technology has disadvantages, is it worth using it at all?


Do I need to use Double VPN, Triple VPN, Quad VPN
We recommend using Double VPN, as this technology really enhances your anonymity.

We will always talk about an integrated approach to security. And Double VPN can be one of the links of your anonymity on the Internet.

We do not recommend using Triple VPN and Quad VPN, as they reduce the speed of your Internet connection and do not create an additional level of protection. That is, speed reduction is greater than the benefits of these technologies.

If you need perfect anonymity, then we recommend that you consider other protection methods, such as TOR, proxies, SSH and others, instead of using Triple and Quad VPN.

We will talk about them in more detail in other articles.

The anonymity of customers is currently more dependent on the number of technologies that the client uses. We want to tell you about parallel VPN technology, the popularity of which is gaining momentum.


What is Parallel VPN
The idea of using Parallel VPN technology came about because of the disadvantages found in Double VPN.

Parallel VPN removes all the disadvantages of Double VPN security.

The essence of the technology is as follows: traffic passes in a double parallel tunnel. Unlike Double VPN, traffic is really encrypted twice at one time.
