What is VPN ?

What is VPN? Virtual private network (VPN) is the network technology that creates a secure network connection over a public network such as the Internet.

With computers and devices connected to the VPN, they can securely transfer the information through the encrypted tunnels created by the VPN. All network traffic is sent over a secure connection to the VPN, keeping information and data safe and secure. Similar to a firewall that protects the information on your computer.

How does VPN work?

Connecting to a virtual private network is usually easy. It is important to start a VPN client on your computer and log in with the credentials. The computer then transfers a secure, trusted key to the VPN server in another country. When you authenticate the VPN client-server connection, all of your Internet communication is encrypted and secure. All web traffic is now routed through the encrypted tunnel created by the VPN. The actual IP address of some users remains hidden, and a current IP address is assigned, which enables the user to hide the physical location and bypass the content filters.


Types of VPNs

There are primarily two types of VPNs, particularly RAS VPN and site-to-site VPN.



When we talk about RAS VPN, it’s about giving someone access to an existing non-public network over the Internet. The private network can be a network set up by a business organization equipped with a database and a network related to the organization or one of its projects.

Remote access is typically based on each IPSec or (SSL) Secure Sockets layer to defend the connection, while SSL VPNs often focus on providing secure access to a single application rather than the entire internal network. Some VPNs offer Layer 2 access to the target network. These require a tunnel protocol such as PPTP or L2TP, which works over the basic IPSec connection.

Site-to-site VPN

The word “location” in this case refers to the physical location where there is a private network. It is also known as a LAN-to-LAN or router-to-router VPN. These two or more private networks in many parts of the world are interconnected via the network and each serve as a single virtual non-public network on the Internet.

Advantages of using VPN

  • Allows you to be at home and access your company’s computers like you did at work.
  • Wherever you have VPN client software on a laptop, you can connect to your business from anywhere in the world.
  • It is almost impossible for someone to tap or interfere with data in the VPN tunnel. 6 measures to protect your network from hackers

Disadvantages of VPN

Aside from the right things VPN does for us, that also has its weak points. The lack of an optimized process of ensuring quality of service (QoS) over the Internet is the most significant inability that VPN technology has. In addition, the level of security and authenticity outside the private network is outside the scope of VPN technology. This incompatibility between many providers only adds to the disadvantages.


Full data encryption is a key element in a VPN. A VPN encrypts all data traffic between the two computers and isolates it for a secure tunnel.
Encryption for devices connected to a VPN goes beyond simply surfing the Internet. It contains VOIP communication, Skype, emails – something that uses an online connection. This gives you more security than a proxy server that only shields your web browsing activity.
