<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">Technology enthusiasts and cybersecurity professionals alike recognize the importance of staying protected online. This is where Virtual Private Networks (VPNs) come into play. Whether you're concerned about securing your connection on public Wi-Fi or considering setting up a DIY VPN for your home, understanding how VPNs work and their critical role in network security is key.</p>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">Here, we’ll explore what VPNs are, how they work, and why they’re essential, especially when connecting to public networks. Plus, we’ll show you how you can create your own VPN setup for home use!</p>

<h2 class="font-bold text-h3 leading-[40px] pt-[21px] pb-[2px] [&amp;_a]:underline-offset-[6px] [&amp;_.underline]:underline-offset-[6px]" dir="ltr">What Is a VPN and How Does It Work?</h2>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">A <b><strong class="font-bold">VPN (Virtual Private Network)</strong></b> is a technology that creates a secure, encrypted connection wherever you access the Internet. Essentially, a VPN acts as a protective tunnel for your data, hiding sensitive information from prying eyes.</p>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">Here’s how it works in simple steps:</p>

 	<li class="text-body font-regular leading-[24px] my-[5px] [&amp;&gt;ol]:!pt-0 [&amp;&gt;ol]:!pb-0 [&amp;&gt;ul]:!pt-0 [&amp;&gt;ul]:!pb-0" value="2">Your internet activity is funneled through this server before accessing the broader internet.</li>

</ol>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr"><b><strong class="font-bold">Key takeaway:</strong></b> This encryption ensures that any data you send or receive is protected from hackers, especially on unsecured networks like public Wi-Fi.</p>

<h2 class="font-bold text-h3 leading-[40px] pt-[21px] pb-[2px] [&amp;_a]:underline-offset-[6px] [&amp;_.underline]:underline-offset-[6px]" dir="ltr">Why Should You Use a VPN on Public Networks?</h2>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">Public Wi-Fi networks, such as those in coffee shops, airports, or libraries, might seem convenient—but they can be very risky. These networks are often unsecured, making them a prime target for cybercriminals.</p>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">Here are the top reasons why using a VPN in public networks is vital:</p>
