What Is A Virtual Private Network (VPN) And How Does It Work?

A virtual private network (VPN) serves as an intermediary between you and the rest of the Internet. Instead of directly communicating with a website, you would use a VPN server to conceal your online activity. Consider the following scenario: you want to transfer money from your bank account to a family member. This can be accomplished by visiting the bank’s website and entering your login information.

If you don’t use a VPN, your username, password, and bank account information are all at risk. Keep in mind that we’re not just talking about cyber criminals here. Your online activity can be monitored by a variety of parties, including your ISP, the government, and even network administrators at your workplace. They could access your data if they had the necessary tools because it is open and unsecured. The diagram below shows how your data can be viewed by those with the necessary tools and technical knowledge (within the data packets).

A VPN, on the other hand, creates a tunnel through which your data packets flow, keeping them safe from prying eyes. Using a VPN encrypts or converts your data into a code that can only be deciphered by the destination (in this case, your bank’s website).

What are the benefits of using a VPN service?

When you browse the web or conduct business on an unprotected Wi-Fi network, you risk exposing your personal information and browsing history. That’s why everyone concerned about their online security and privacy should invest in a virtual private network or VPN.

Consider how many times you’ve been on the move, checking your bank account while standing in line at the doctor’s office or reading emails while waiting in line at the coffee shop. Any data transmitted during your online session could be exposed to eavesdropping by strangers using the same network unless you were logged into a private Wi-Fi network that required a password. A VPN’s encryption and privacy secure your online activities, such as sending emails, buying online, and paying bills. VPNs can also help you browse the web anonymously.

VPN security: What does a VPN conceal?

  1. Your internet browsing history
  2. Your IP address and location
  3. Your devices

What a VPN does to protect your IP address and privacy

VPNs essentially build a data tunnel between your local network and an exit node located thousands of kilometers away, creating the illusion of being in another location. This feature enables online liberty, or the ability to access your favorite apps and websites on the go

Consider the function of a virtual private network in further detail. VPNs encrypt data sent over a Wi-Fi network. Encryption renders data unintelligible. Data security is critical while utilizing a public Wi-Fi network, as it prevents other network users from spying on your online activity.

There is an additional aspect to privacy. Your internet service provider can see your entire browsing history if you do not use a VPN. Your search history is hidden when you use a VPN. This is due to the fact that your web activity will be associated with the VPN server’s IP address rather than your own. A VPN service provider’s servers may be located all over the world. That means your search activity could appear to come from any of them. Keep in mind that search engines track your search history as well, but they will associate that data with an IP address that is not yours. Again, your VPN will protect your online activity.


You should be able to keep track of your browser history, IP address, and current location without revealing them to others. If this information falls into the wrong hands, you could be in danger. It is possible that your identity will be stolen and used maliciously by someone. Another way for cybercriminals to steal your money is through bank account hacking. To avoid all of this, you must use a VPN. If you have any questions about VPN security, please leave them in the comments section below.
