Cloudflare is rolling out a new mobile VPN service called Warp that's built on top of its 18.104.22.168 DNS resolver.
Personal VPNs have a lot of expectations, and they aren't suited for all of them. But there are some scenarios that are ideal for personal VPNs.
The main point of using a personal VPN is to surf the interwebs in privacy, away from prying eyes. Lock down the browser before starting up the personal VPN for maximum benefits.
People expect the personal VPN to hide or otherwise obscure what they are doing on the Internet. Some are better than others, but it is difficult to evaluate them on technical merits. Duo Labs provides guidelines on how to pick a personal VPN that matches your threat model.
