What is VPN (Virtual Private Network)?

Virtual Private Network

VPN stands for Virtual Private Network that allows a user to connect to a private network through the Internet in a secure and private way. The virtual private network is gaining popularity among users for several reasons. In this article, I’m going to simplify what is a VPN and its types.

Definition of VPN (Virtual Private Network):

Virtual private networks provide connections between two or more private networks that access public networks, such as the Internet. VPN connections on the Internet are similar to wide area network (WAN) links between these sites. VPNs are used to protect your online traffic against espionage, interference, and censorship.

Definition of VPN

VPNs establish encrypted connections, called VPN tunnels, and all traffic and Internet connections go through that secure tunnel. Therefore, keep the user data safe and private. They are more affordable and much faster.

A VPN is a service that is registered online for a small monthly fee. Once you have an account, your VPN service should be “on” when you are online. A VPN, in action, takes your Internet connection and makes it more secure, helps you to remain anonymous and helps you bypass blocks and access censored sites. The VPN key is that it gives you a temporary IP address and hides your real IP address from each website or email with which you connect.

Why Virtual Private Network?

Your IP address is a behind-the-scenes number provided by your Internet service provider for computers that allows you to go anywhere on the Internet. It’s like the number of the house in your street/area. Therefore, your IP address also provides your computing location, at home, or on the road. That annoys many computer users.

Therefore, online businesses of all types monitor the activity that comes from the IP address. Finally, hackers can divide them into networks and sometimes take control of the devices through their IP address.

Types of Virtual Private Network:

The two basic types of VPN described below.

  1. Remote access VPN
  2. Site-to-Site VPN

Remote acess VPN:

Remote access VPN allows users to connect to private networks and access services and resources remotely. Connections between users and private networks occur through the internet and connections are secure and private. Remote access VPN is useful for home users and business users.

A company employee, while traveling, uses a VPN to connect to his company’s private network and access files and resources from a private network remotely.

Remote access VPN

The main benefits of remote access VPNs are easy configurations and uncomplicated use. With the right software, this type of VPN can be easily accessible for newcomers and veterans alike and is ideal for personal use. However, it may be inappropriate for (and even incompatible with) large-scale commercial needs.

Site-to-Site VPN:

Special tools for VPN websites require scale encryption. Where the Site-to-Site VPN is based on Router-to-Router communications. In this type of VPN, one router acts as a VPN client and another router acts as a VPN server. Communication between the two routers does not begin until authentication is validated. Site-to-site VPNs commonly used in large enterprises.

Advantages of Virtual Private Network:

More privacy:

Your connection cannot be linked to your computer and yours. You can visit any website and your ISP doesn’t know where you are going.

More security:

A VPN connection is very safe. The network can protect from hacking and all your Internet activity can encrypt and unreadable in transit.

Reduce costs:

After the VPN network created, maintenance costs are very low. Moreover, if you choose a service provider, network settings and supervision are no longer a problem

More website access:

VPNs works perfectly for accessing blocked websites or for getting around Internet filters. No more blocks of censorship. They can not prevent you going to websites based on an IP address.

More anonymity:

Thanks to a VPN, you can browse the Web in the most complete anonymity. Compared to hide IP software or IP proxy servers, the advantage of a VPN service is that it allows you to access Web applications and Websites in a completely anonymous way.

Conclusion: VPN has played a big role in getting private networks from cyber attacks. Therefore, with the information above, you get a brief idea about a Virtual Private Network (VPN). If you have questions, please specify in the comments section below.
