Outline VPN  Outline VPN is a free and open-source tool that deploys Shadowsocks servers on multiple cloud service providers. The software suite also includes client software for multiple platforms. Outline was developed by Jigsaw, a technology incubator created by Google.[3]   The Outline Server supports self-hosting, as well as cloud service providers including DigitalOcean, Rackspace, Google Cloud Platform, and Amazon EC2. Installation involves running a command on its command line interface, or in the case of installing on DigitalOcean, its graphical user interface. Outline has three main components:   Outline uses the Shadowsocks protocol for communication between the client and server. Traffic is encrypted with the IETF ChaCha20 stream cipher (256-bit key) and authenticated with the IETF Poly1305 authenticator. Outline is free and open-source, licensed under the Apache License 2.0, and was audited by Radically Open Security and claims not to log users’ web traffic. The Outline Server supports unattended upgrades. Outline is not an anonymity tool, and it doesn't provide the same degree of anonymity protections as Tor, which routes traffic through three hops rather than just one and also protects against attacks like browser fingerprinting. In March 2018, Max Eddy of "PCMag" stated that a preview version of Outline VPN was "startlingly easy to use" and "removes privacy concerns associated with VPN companies". However, Eddy criticized the software for not encrypting all traffic on Windows, and warned users that "individual use may lack some anonymity compared [to] large VPN companies". Since version 1.2, the Outline Windows client came out of 'Beta', effectively beginning to encrypt all traffic from the device, in par with the Outline clients for macOS, Chrome OS, Android, and iOS.
