With these, you’ll get different levels of security and specifications depending on your specific needs. VPNs also come in various protocols which will determine how data is routed through a connection. In the case of a major cloud provider like AWS and its site-to-site VPN offering, it can provide a secure, encrypted connection between your office or data center, directly to an AWS gateway and ultimately your private cloud resources. For instance, a site-to-site VPN is an encrypted connection between two or more networks on an ongoing basis. There are other types of VPNs that differ in how they work from the above example, a personal VPN. And you can use streaming services without your ISP detecting it and slowing down your speeds. Since your IP address is hidden from your ISP and other third parties, you can often get around geo-restriction by connecting to a VPN server in other locations. VPNs can protect you when using public WiFi networks by encrypting your location and activity and by providing a secure connection between you and the internet. The VPN works to encrypt the entire process in such a way that your ISP and other third parties can’t peek at what websites you visit or data that you send or receive online. The VPN client on your device encrypts the data, it travels through your ISP, encrypted, to your VPN server where it handles the rest of the DNS lookup process. How a Virtual Private Network worksĪ VPN works by tunneling your traffic through an encrypted tunnel hiding your IP address and encrypting your data. Therefore, to ensure more security while using the public internet, many adopt a VPN solution. This has often been the case for those using streaming services like Netflix or YouTube. Since your activity is known, your ISP can intentionally slow down your internet if a high demand of bandwidth is detected. Since your location is known, you are subject to geo-restrictions enforced by your internet service provider. What if you aren’t at home or on a secure network? What if you are at a coffee shop or a hotel, using their public network? Well, there’s the risk of a man-in-the-middle-attack, Wi-Fi sniffing, and attackers even setting up their own fake router to intercept your data. Your IP address reveals your location and your ISP keeps information on your activity. Now, there are a few problems with this flow: And if a site uses HTTPS, once your request arrives there, data is then encrypted between you and that server. The ISP then performs the DNS lookup keeping logs of your request, sites you connected to, etc. From your router, the data goes to your Internet Service Provider (ISP) and gets assigned an Internet Protocol (IP) address on their network, pinning you to a general location in the world. The device request goes through your router with a packet of data including what device made the request and what is being requested, among other things. Let’s look at a typical device accessing the web. A VPN connection will encrypt your internet traffic and route it through a remote server, keeping your activity hidden from hackers, ISPs, and any third-party with malicious intent. A VPN, or Virtual Private Network, is a tool that allows you to create a secure and private connection between your device and the public internet.
