It is a secure tunnel that all traffic and communication pass through. This helps ensure that sensitive data is safely transmitted between servers. <\/p>\n\n\n\n<p>VPNs can be used to access region-restricted websites, shield your browsing activity on public Wi-Fi, and more. VPNs were originally created to connect business networks together securely over the internet or allow users to access a business network from home.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Set up a VPN<\/h2>\n\n\n\n<p>There are many reasons why someone would need to set up a VPN. Here are some of them:-<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Security:<\/strong> Protecting the user from potentially harmful networks.<\/li><li><strong>Anonymity:<\/strong> Hiding the user&#8217;s true location and granting them freedom-of-use <\/li><li><strong>Bypass:<\/strong> Giving the user access to geographically blocked websites.<\/li><li><strong>Business Use<\/strong>: Connecting the user to their company&#8217;s private network.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Types of VPN<\/h2>\n\n\n\n<p>There are two types of Virtual Private Networks:-<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Remote Access VPN:-<\/strong><\/li><\/ul>\n\n\n\n<p>Like the name suggest, Remote Access VPN allows users to connect to and access a private network remotely. This secure and private network connects the endpoint user to the encrypted network over the internet.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Site-to-Site VPN:-<\/strong><\/li><\/ul>\n\n\n\n<p>Also known as Router-to-Router, Site-to-Site VPN works by connecting two or more separate geographical locations together through a virtual network bridge. This makes it possible for those separate locations to connect to their very own private network. <\/p>\n\n\n\n<p>The way this works is, the main router serves as the <strong>VPN Client<\/strong> while the other connecting router serves as a <strong>VPN server<\/strong> that connects directly to the VPN Client&#8217;s network. That connection is only possible between those two networks after passing through secure authentication which makes Site-to-Site a very secure method of network communication.<\/p>\n\n\n\n<p>To explain further, let&#8217;s use an example. Let&#8217;s say there are two sites, Site A and Site B. Site A hosts the main network for the company and therefore acts as the VPN Client. Site B directly connects to Office A&#8217;s VPN and therefore acts as a VPN server. Between both A and B there is a virtual bridge that connects both of them.<\/p>\n\n\n\n<p>In business, if the connection is made between two offices of the same corporation, it is called <strong>Intranet<\/strong>, and if the connection is made between the offices of two separate corporations, it is called <strong>Extranet.<\/strong><\/p>\n\n\n\n<p>Those are the two main VPN Types. There are also different types of VPN Protocols that we will walk through soon.
