https://www.wired.com/story/cloudflare-says-new-vpn-service-wont-slow-you-down/ > Virtual private networks (VPNs) can help protect your internet traffic from prying eyes. VPN services route your email, web browsing, and other internet activity through the service provider's servers, making it appear to outsiders that you're only accessing those servers. VPN services help users in China, for example, reach blocked sites by making it appear they’re accessing something else. They also prevent your internet service provider from snooping on the pages you visit, and encrypt web connections that might otherwise be exposed, a handy feature on public Wi-Fi networks. > But VPNs typically come with some major trade-offs. One of the biggest is speed. After all, your traffic must pass through someone else's server before reaching other websites. That extra step inevitably introduces lag. Security company Cloudflare claims its new mobile-only VPN service will be as fast, if not faster, than a traditional mobile connection.
