Before that we introduce you Top 10 VPN of 2019 you should know what is VPN and how it works, is it safe to use a VPN or not?
What is VPN
Afghanistan24: Most of us have heard the word VPN at least once, at least on filtering issues (explained in the last paragraph). VPN stands for “Virtual Private Network“
VPN extends a private network through public networks such as the Internet. Suppose, for example, that a company’s private network is restricted to that company’s premises and that we must go inside to access it. But sometimes we don’t have physical access to that location, but we need to connect and work with the private network there. For example, when you’re traveling and needing to connect to the network quickly, or nowadays the term telecommunications is used, users are connected to the network using VPN connections and doing their job. VPN connections are completely secure and unreadable and decrypted.
In the past, the intranet was used to extend private network data. An intranet is a network that does not use the Internet to communicate and exchange and is a completely proprietary network of companies. Intranets have no connection to the Internet without an extranet interface. That is, the intranet can be defined as a personal internet for companies that use Internet protocols and standards but are much more restricted and only accessible to certified people. For example, banks, universities, etc. are often intranet type.
Setting up an intranet is very expensive and is not possible for most companies. On the other hand, its security and unauthorized access is always a major threat to intranet networks. For this reason, the VPN communication method has been introduced which is cheaper, safer, more flexible and faster.
How does VPNs Company work?
We said that VPNs provide a secure environment for the user to communicate with the destination over the Internet. By providing a tunnel between the user and the server, which is often directly connected to the company’s intranet and encrypts the transmitted data, it provides a completely secure space. Like the picture below:
Filter VPNs and their Risks
In the section above we explain how enterprise VPNs work. This section is about VPNs that are often referred to as filter breakers. You may have used these filters as well, and your need may have been met, but most people, unfortunately, don’t care about the security of their information and think that these filters and VPNs aren’t a threat to them.
VPNs that act as a filter breaker by creating a tunnel between you and the purchased (or free) server and encrypting information make our requests for telecommunication filters and Internet Service Providers (ISPs) incomprehensible without Difficult to rule them out. They will then send the request they received to the website or service you requested. That service or website also sends the response to the VPN server (because it recognizes it as the requestor) and the VPN server encrypts the response and again bypasses the ISP and ISP filters and decodes the client-side using a tunnel. And so you use the website or service you want. Like the picture below:
If you look at the picture above, it’s all very easy to get your hands on it. If the VPN server is controlled by a hacker, he or she will be able to get in touch with you and the website in question. That is, if you ask for account login, as the password and username are sent along with the request, it can easily view them! It is important to note that, if not all filtering servers, many of them through Identity-Identity Information (the only website that does not know your identity and recognizes the VPN server as the opposite) while the VPN server itself does not Know any problems!) And other sensitive information such as passwords, browser cookies, banking information, and so on.
On the other hand, because these services are illegal and the mechanism of their work is that their identity is secret, they will often not be able to sue, for example, if your password is stolen, stolen, and neither by the police nor by yourself. It won’t come back. It is best to change your password quickly.
To give you a better understanding of these risks, let me give you an example: Suppose A cannot send a letter directly to B. Instead of communicating directly, Person A puts the letter in a specific place and goes home. A third person whose identity is unknown to A picks up the letter. It reads it, may change it, then sends it to person B and does the same in the response process.

Advice to all VPNs user
Don’t use filters as much as possible! If you use it, don’t even type in sensitive information like your bank card number, internet password, etc … until you send it. If you have to, make sure you only go to sites that use the HTTPS protocol instead of HTTP. In such sites, information is encrypted between you and the site, which is even incomprehensible to your VPN and filtering server. Otherwise, be sure your information is read by someone!
Types of VPN
We have two types of VPN for different use
- Remote Access VPN
- Site to Site VPN
What is a Remote Access VPN?
Remote Access VPNs allow individuals (and not companies, branches, etc.) to connect to a company’s private network. These users can access their resources by connecting to the company’s VPN server. Among those who use this type of VPN are long-distance employees.
Two basic components are needed to communicate in this type of VPN
- User-side application
- NAS stands for Network Access Server and controls communication from the server. The NAS may operate as a dedicated server on the corporate network or as a software that runs on shared networks, collecting user authentication information and allowing them to connect to the corporate network by reviewing them.
- User-side application: The user must use software to connect to the VPN server that encrypts the transmitted data and decrypts the incoming data in addition to communicating and authenticating. Most operating systems (including Windows, GNU / Linux, etc.) provide embedded applications to connect to a VPN server.
What is Site to site VPN?
The Site to site VPN type allows branches of a company to communicate with each other. This type of VPN is important when hundreds of people want to connect to the server. Instead of using each type of “remote access VPN”, they are divided into groups that, as branches of that company, are connected via “VPN location to location” and allow each other resources to be used. The components needed to set up this type of VPN are the same as before, but most will no longer need a client on every computer.
This type of VPN is divided into two types
- Internet-based VPNs
- Extranet based VPNs
What is internet-based VPNs?
If the company has one or more remote locations that want to connect to each other and share their local network, they use an Internet-based VPN.
What is Extranet based VPNs?
If companies or organizations want to connect with each other but do not need Internet access, they can connect their intranet network to another intranet using an extranet-based VPN. This way they can work together and protect their intranet network.
