VPN<\/a> vs. Proxy<\/a>. Which one is better? It depends on you.<\/p>\n\n\n\n

Although VPNs and proxies may seem similar on the surface, as they both provide Internet security and privacy, underneath, they are two completely different creatures\u2014 born and raised to provide different solutions.<\/p>\n\n\n\n

VPNs were designed to \u201cvirtually\u201d link two geographically distant computers or networks using risky networks such as the Internet. Conversely, proxies were designed to add structure to complex distributed networks by centralizing all requests and responses. Therefore, both solutions provide different levels of privacy and security as byproducts.<\/p>\n\n\n\n

In this article, you\u2019ll learn the top 6 key differences between VPN vs. Proxy. You’ll also learn when to use one as an alternative to the other.<\/strong><\/p>\n\n\n\n

          What is a VPN? <\/h2>\n\n\n\n

          M\u1ed9t Virtual Private Network (VPN)<\/a> is a group of virtually interconnected clients and servers. As mentioned earlier, VPNs were designed to extend local networks geographically. Since VPNs don\u2019t rely on physically connected systems, their networks can span worldwide.<\/p>\n\n\n\n

          A VPN typically uses the Internet as a medium. VPN clients and servers use the grid (the Internet) to exchange packets, and to keep it secure, they create a kind of “secret underground” tunnel. Nobody with access to “this grid” (ISP, hackers, government, etc.) would be able to tell what is going on and through those VPN tunnels.<\/p>\n\n\n\n

          a. How does a VPN work?<\/h3>\n\n\n\n

          To establish these hidden tunnels, VPNs use encryption. Both the client and server agree and share a set of encryption-decryption keys for creating this tunnel.<\/p>\n\n\n\n

          Let\u2019s say you are connected to a VPN server and want to browse the Internet. The following is the message flow that illustrates a standard VPN client-server connection.<\/strong><\/p>\n\n\n\n

            \n
          1. Before your Internet request for a service (i.e., HTTP or P2P) goes out, the client\u2019s VPN process takes control.  <\/li>\n\n\n\n
          2. The VPN client encrypts the IP packet\u2019s data using the public key received from the server and then encapsulates the request with the new destination IP: the VPN server.<\/li>\n\n\n\n
          3. The client transmits the encrypted packet across the Internet towards the VPN server. <\/li>\n\n\n\n
          4. Anyone across this path, either a coffee shop hacker, ISP, government, or your neighbor, would still be able to capture your packets but never to make sense out of your data.<\/li>\n\n\n\n
          5. The VPN server receives, opens, and decrypts the packet using the private key. <\/li>\n\n\n\n
          6. The VPN server decapsulates the original client\u2019s packet, then forwards the original request using the server\u2019s VPN IP to the intended destination (for example, youtube.com or facebook.com). <\/li>\n<\/ol>\n\n\n\n

            b. When Should you use a VPN? <\/h3>\n\n\n\n

            Widespread use cases are (but are not limited to): Extending private networks, circumventing geographical restrictions, bypassing censorship, protecting true identity, improving branch-headquarters security, adding security when using public networks, and more. <\/p>\n\n\n\n
