How VPN Service Works

VPN - ingenious, secure and simple

You probably already know that VPN (Virtual Private Network) encrypts and redirects your traffic through a dedicated server.

In fact, this is true and not true.

VPN technology itself was designed to create private networks, which those networks might not even having a gateway to communicate with the rest of the Internet. Computers within the virtual network "saw" each other as if it were a physically isolated network.

This technology formed the basis for the modern VPN.

A tunnel is launched between the user's device and the VPN, which is additionally encrypted. In fact, a network of two devices is used, one of which is also a gateway to the Internet.

This scheme has 3 major advantages:

  1. Absolutely legal methods of data transmission are used, the age of which are only slightly less than the age of the Internet;
  2. With encryption (used today in 100% of cases), it is impossible to gain unauthorized access to the transmitted data between the client and the server;
  3. It is possible to transfer data directly to the VPN server, bypassing many intermediate nodes of normal data transfer, which can increase the connection speed.

Due to the fact that VPN services use the same technology necessary for the normal operation of state and many corporate networks, it is practically impossible to prohibit the Virtual Private Network at the legislative level (relevant for countries with Internet censorship).

Today, there are several reliable VPN tunneling protocols, on the basis of which VPN services software works. The most common are OpenVPN and IKEv2. The most technologically advanced and actively implemented is WireGuard.

These protocols also allow data to be encrypted inside the tunnel. The most common effective encryption standard is AES-256, which is used in the vast majority of VPN programs and applications.

AES-256 is recognized as the official data protection standard of the US government (see article on Wiki)

Thus, VPN is a legal, simple and effective technology that has been proven over time.

Not all VPNs are the same

The previous section outlined the technology. But the weak point of any protected system is in its final performance.

Of course, if you were to set up and configure your own open source VPN server then your system would be quite secure.

But can we trust a third party companies?

Can we be sure that they took everything into account, really applied encryption, implemented protection against leaks, and so on?

It's a difficult question. After all, if we’re just using a VPN to register another free account on a smartphone games, then it’s not a big deal.

But what if we use VPN all the time? Is our personal data or information that we want to hide from the Internet Service Provider (ISP)secure?

In this case, we need choose a VPN that we can trust.

A list of the main tasks you should think about when assessing the quality of a VPN service:

  • Location masking (IP addresses);
  • Protection of transmitted and received data, including in public WiFi;
  • Bypass geo-restrictions;
  • Unblocking websites;
  • VPN blocking bypass (in countries with strong censorship);
  • Increased streaming video quality.

Few VPNs can meet all of these objectives and it’s easy to make a mistake in choosing a service.

Error choosing VPN

What happens if you don't go into details and connect to the first VPN that comes along?

Let's take the example.

Recently, while we’re analysing reviews of VPN on Reddit, we paid attention to one comment to positive feedback about one of the major VPN providers. It said that VPN has a bad service as it didn’t bypass the geo-restrictions on streaming from the Hulu site.

At the same time, the service doesn’t have a specialization for bypassing geo-blocking by popular media materials. But he perfectly bypasses the Great Chinese Firewall and helps the residents of China to gain access to blocked sites outside the country.

So is it good VPN or bad?

The main mistake of inexperienced users is choosing a service at random, without delving into its capabilities.

In the next section, we will list the main characteristics to take in account when choosing your VPN, and in the chapter Top 10 VPN Test Results you will find experimentally obtained parameters to quickly select your VPN.

How VPNs Are Different

The main parameters of VPN services in 2021:

  • Number of platforms supported... It is better when applications are offered for all OSs.
  • Countries... A good indicator is 50 countries or more.
  • Number of servers... The more servers there are, the more evenly the load is distributed. The indicator can reach 6000. But there are services with less than 10 servers.
  • Speed... Average internet speed with a VPN connected (taking into account ISP capabilities).
  • Speed ​​stability... It can change at different locations and depending on the time of day.
  • Connection protection functions... For example, all good VPNs have a Kill Switch feature (read more at the end of the article).
  • Support for Netflix and other streaming services... Only large VPN providers can bypass the protection of such resources.
  • Torrenting support... Not all VPNs allow P2P uploads.
  • Protocols used... Providing the user with the choice of the tunneling protocol is a sign of a high-tech service. Software running on one protocol, as a rule, is not adapted for high performance and may not work in some networks.
  • Number of simultaneously used devices...
  • Logging policy... Most of the services claim that they do not record user activity, but only a few use specialized equipment for this, confirm this indirectly, or undergo an independent audit.

Best VPN overall

ExpressVPN - the best VPN

The latest testing, conducted in the second half of 2021, identified three leaders. It was difficult to single out the absolute leader, but given the large number of positive reviews and the use of expensive equipment by the service, which excludes the possibility of collecting and storing information about user activity, the best VPN overall is ExpressVPN...

Top 10 VPN Test Results

1. ExpressVPN

  • WireGuard
  • Good streaming support
  • Chameleon technology
  • Low price (for 2 years)
  • Low average speed
  • Small server network considering the number of countries
  • Doesn't accept Bitcoin

VyprVPN is an example of a relatively weak VPN service that is becoming one of the best. After revising its privacy policy, adding a performance protocol and focusing on streaming support, VyprVPN has been ranked 6th on our list.

The only drawback we identified is the relatively low speed stability. Most likely, this is due to the fact that the service has only 700 servers in 64 countries, and this negatively affects their load.

Briefly about VyprVPN:

  • Jurisdiction: Switzerland (known company Golden Frog)
  • Speed ​​over 20-110 Mb/s
  • 700+ servers in 64 countries
  • Supports all systems including Android TV

  • Netflix
  • Port forwarding
  • Virtual IP addresses
  • No modern protocols
  • Kill Switch problem

* Testing revealed that most countries are virtual. This means that the IP addresses provided are not physically located on servers in the specified countries.

PureVPN is one of the most controversial VPNs out there today. Many people think it has a dubious reputation, but after running a number of tests, we believe it is reliable.

PureVPN does not have any special advanced features, but it can be indispensable in cases when you need to access IP addresses of almost any country in the world.

Subtle But Important Features of a Good VPN

Bypass geo-restrictions of media content

In recent years, VPNs have evolved into feature-rich tools that literally break boundaries and limits. They are now not simply used for work, but for play as well.

With a VPN, you can virtually change your location and access video and audio content from Netflix and other geo-restricted video services and TV channels.

Video services try to block the IP addresses of VPN servers, so not all services are capable of fully working with popular streaming sites. This is especially true for BBC iPlayer, HBO, Amazon Prime Video, Hulu and Netflix. Choose only VPNs that have been tested with these video services. Read more in the review VPN for streaming...

Protection against leaks in case of violation of the VPN tunnel

VPN is designed in such a way that data protection occurs only inside the virtual tunnel. At the same time, for the user there is no difference in how the traffic flows - in the usual way or through the tunnel.

This is where VPN's weakness lies. You simply won't notice if the VPN goes down for some reason.

Even if it automatically reconnects, some of the data may have been sent without protection.

Leakage can occur through:

  • problems on the side of the VPN service
  • Unstable internet
  • Changing WiFi points
  • Automatic updates of VPN software
  • Change of location

But, fortunately, there is an effective way to protect against such leaks - Kill Switch technology. It blocks all traffic outside the VPN channel. There is also a Kill Switch variant that abnormally closes the specified applications. Read more in the review VPN with Kill Switch...

What to do if VPN is prohibited or blocked?

Is using VPN legal everywhere?

Countries with strong censorship may have laws or technical means that prevent anonymizers like VPNs from working.

We have compiled a list of countries and the specifics of their VPN countermeasures. If you are on one of them, it may not be possible or secure to use a regular VPN.

Use the following services to bypass blocking and mask your VPN connection:

VPN restricted countries
 Service for circumventing restrictions
VPN services not controlled by the government are legally prohibited. Together with this, the so-called ‘Great Chinese Firewall’ operates in the country. It not only blocks IP addresses, but is also capable of detecting and blocking VPN activity.
ExpressVPN (not available in all provinces)
NordVPN (with obfuscation enabled)
Surfshark (with NoBorders enabled)
The degree of blocking is highly ISP dependent.
Russia Belarus
There are laws that prohibit the use of a VPN to bypass site blocking. There are no known cases of their use.
Everyone except Surfshark
Iran Iraq Turkmenistan
Blocked IP addresses + DPI (Deep Packet Inspection)
ExpressVPN (not available in all provinces)
NordVPN (with obfuscation enabled)
Surfshark (with NoBorders included)
Turkey Egypt
Blocking IP addresses
Access to VPN sites is limited


Cooltechzone does not call for breaking the law. In cases where the VPN sites mentioned above are legally prohibited in your country of residence, stop using them. Otherwise, we are not responsible for the consequences.
