What is a VPN?

Virtual Private Networks (VPN) are online security tools, which create encrypted tunnels that can transfer your data securely through the Internet or any private networks. Even when you use a public Wifi network, with the help of VPN you can protect your data from the eyes of hackers. Most corporate companies never transfer any information without a VPN. It means for those who require secured data transfers on the Internet, VPN is the best choice! This VPN guide is written in such a manner that will let you know all about Virtual Private Networks (VPNs).

Why You Need a VPN?

  • Overcomes Geo-restrictions: With a VPN, You can access Hulu, HotStar, BBC iPlayer, Pandora, or any live streaming service even when you are away from the service provider’s country.  We might have come across so many people who travel overseas for higher education, job, or any other purpose. In such a case, it is difficult for them to access websites from their country as a result of geo-restriction. It blocks websites for the people in their country to access the websites from other countries. Few of the countries that follow geo-restrictions are Iran, China, etc. So next time when you plan for travel to such countries, be sure to get a VPN account to get connected with the web pages that you visit often. This VPN guide recommends a good VPN for frequent travelers while they plan for it. 
  • Secure accesses: The Internet communication is not always secured as hackers, Trojans, snoopers, etc. can harm your data by any unauthorized data access due to inadequate security and privacy measures. When we send our sensitive information such as bank account details, passwords, etc., anybody could hack our data and may use it improperly. It is a worrying fact, and it has to be dealt with caution in prior than it happens to us. Yes, the VPN guide suggests you subscribe a VPN connection when you send sensitive or any personal information via public or private networks. 
  • Bypasses Firewalls: A firewall is a virtual wall that blocks requests from certain countries, places, any set of websites, or any other matching conditions. For example, many educational institutes have firewalls to block social media websites, gaming websites, etc. A VPN is capable of bypassing such checks and can get you the access you need. This is not an illegal activity, and the usage of VPNs are widely accepted by governments all around the world. 
  • Anonymous online activities: When you use the Internet, anyone can come to know your Internet Protocol (IP) address. An IP address is an identification of your system or electronic device in the public or private network. Even the physical address and other details can be found using an IP address. It means that there is a potential risk of letting your information to others when you leak the IP. To be on a safer side, VPNs are the best solutions. VPNs hide the actual IP address and replace it with the IP address of its servers. So, nobody could track the actual IP from where the requests arise, and you can remain anonymous on each of your online activities. Just read the VPN guide further for more useful information.
