What is VPN? (Virtual Private Network)

A VPN is, by a simple definition, a network that requires authentication before a user can access it; consider for example a campus or company network that requires a username and password. So how exactly does a VPN protect your data? The VPN acts as a launching pad for users before they access sites on the internet.

When a user launches a VPN application, it creates a “tunnel.” This passage is a secure line of communication between the computer and the VPN, meaning outside observers cannot see the data passing between them. As an additional layer of security, the data passing through the tunnel is encrypted, altering the information in a particular way. Computer and the VPN, both are aware of the encryption key, so when the data lands on the destination, it gets decrypted and reinstates its original form.

That strengthens the fact that Hackers have no chance to snoop around your privacy. This secure tunnel staves off malicious applications and thinkers sitting across the lines. Even an ISP (Internet Service Provider) is only able to see the unintelligible strings of data.

Once you connect to a VPN, you can browse the internet as usual, with one major exception: Your computer behaves as if it is located in the network, rather than wherever you are. This means that when you access a site while logged into a VPN, the data packets sent will not have your address on them, but instead that of the VPN.

Benefits of Having a VPN are Mainly Intended to

  • To safe keep your identity.
  • To get users the data they are looking on the web.
  • Enabling access to Youtube contents which are prohibited for other remote users.
  • To give users access even to the blocked websites which are only viewable in the local domain.
  • Once you are secure through a VPN, you use intermediate VPN servers to connect to the internet, and use is anonymous browsing.
  • You can use VPN to access your home country’s network as if you were in the region.

Bad Sides of a VPN

No questions, VPNs are handy, but they are still not untouched by problems. The most intricate problem with VPNs is that they can rattle your download speeds. Since data passing between the user and the VPN is encrypted, it takes more time keeping the downloading process delayed and prolonged. And don’t forget that the data also gets decrypted after reaching the destination.

Another bottleneck with VPNs is that some larger websites have decided to crack down on them. Let’s take Netflix for example. To keep different users from accessing its U.S. library, Netflix routinely blocks users if it detects they are coming from a VPN. This does not only apply to people trying to get around geoblocking. if you live in the United States and work to access Netflix through a VPN, the site may detect it and block access.


VPNs are an excellent option for anyone looking to protect their privacy online. They are not foolproof, however, so take care when using one. Be aware of your country’s surveillance laws, and the privacy policies of any VPN you use.
