The background of VPNs

A push to safeguard and encrypt internet browser data has existed since since people started accessing the internet. In the 1960s, the US Department of Defense began participating in programmes focusing on the encryption of internet communication data.

In what way does VPN work?

By allowing the network to transmit your IP address through a specially set-up remote server operated by a VPN host, a VPN can hide your IP address. In other words, if you use a VPN to browse the internet, the VPN server becomes the source of your data. As a result, neither your Internet Service Provider (ISP) nor other parties will be able to see the websites you visit or the data you transmit and receive online. A VPN acts as a filter that “gibberishes” all of your data. Even if someone were to obtain your data, it wouldn’t be useful.

How does a VPN connection benefit you?

Your online data transmission is hidden by a VPN connection, which also shields it from prying eyes. Anyone with network access and the desire to examine it can access unencrypted data. Hackers and online criminals are unable to decode this data when using a VPN.

Is there a reason to use a VPN connection?

Normally, when you connect to the internet, your ISP configures your connection. It follows you using your IP address. Your ISP’s server, which can record and show everything you do online, handles the routing of your network traffic.

Although your ISP may appear to be reliable, it may give your surfing history to third parties like advertisers, the government or law enforcement. ISPs are susceptible to cybercriminal assaults as well: Your private information may be at risk if they are hacked.

Are VPNs Secure?

VPN security should be taken into account. Your internet traffic is diverted to and passes through the servers of the VPN service you’ve selected. Therefore, if the VPN provider firm so desired, it could observe everything you do. Selecting a reliable VPN that does not maintain user data logs that can be shared with third parties is therefore essential.

As a result, it’s crucial to investigate a VPN before utilising it. 

With a VPN, you can surf securely

Your browsing activity is encrypted with a VPN, and this encryption can only be unlocked with a key. Your ISP cannot tell where you are browsing because only your computer and the VPN have access to this key. Although different VPNs employ various encryption techniques, they all generally follow three steps:

  1. Start your VPN as soon as you are online. Between you and the internet, the VPN functions as a secure tunnel. This tunnel is undetectable to your ISP and other outside parties.
  2. Your device is now connected to the VPN’s local network, and you can change your IP address to one that the VPN server provides.
  3. Now that the VPN has protected all of your personal data, you can freely browse the internet.

Does a VPN Cause Internet Connection Slowdown?

Perhaps you’ve heard that using a VPN can make your internet connection slower. Some VPN services actually have this impact, it is true. In the end, a VPN offers an encrypted connection through which your data is sent to a faraway server. Your internet connection may become slower as a result of this taking longer. This isn’t always the case, although.


You and the internet are connected securely over a VPN connection. Your whole data traffic is routed over an encrypted virtual tunnel using the VPN. When you access the internet, this masks your IP address, hiding its location from view. A VPN connection is also safe from outside threats. That’s because nobody else can access the data in the encrypted tunnel because they don’t have the key, only you can. You can access geographically restricted content from any location with a VPN. Many streaming platforms are not available in every country. Using the VPN, you can still access them.
Now that the VPN has protected all of your personal data, you can freely browse the internet.
