Usability of VPN :

These are used for security and some people use this to unblock websites using a proxy. So let’s talk about these factors.

  1. For Security Purpose: As we have already told you above that VPNs work by making a secure tunnel layer between you and the proxy server. For this reason, these are popular so much. These are also being used by companies on a larger scale so that employees may work securely being on the same network. It helps in decreasing the chances of data breach at a better level. It is better for security purpose but sometimes due to some vulnerabilities or any type of misconfiguration may cause data breaches may happen as you have seen the NordVPN example above. So VPNs are good for security but you should be wise in choosing a VPN service. Another use of these is to hide the IP addresses, this is a good idea to hide your actual IP address.
  2. For Proxy Use: VPNs are also used by people not only for security purposes but also for Proxy purpose. By using this as a proxy, helps users to unblock websites which are banned in there countries’. Even in some companies, employees use this proxy feature to access their home computer or laptop from their office. So this proxy technology is making a huge difference.

Sometimes it may possible that you will think that is it illegal to use a VPN for a proxy? The answer for this is if you are doing illegal activities such as hacking then it is illegal rather than it is legal. But in some countries, it is illegal to use a VPN for any reason. You may read the full list of the countries here who have banned VPNs. If you are thinking of doing wrong activities and you have an idea that no-one will catch you as your IP address is hidden then you are wrong.

It is true that your IP address is hidden because of using VPN but you should keep noticing that your IP is being captured by VPN so if there will be a problem then, in that case, police officials may ask the VPN provider to give details and then you’ll be caught.
