  A scalable overlay networking tool with a focus on performance, simplicity and security

  

- Nebula ( https://github.com/slackhq/nebula ) is similar to the other two. It was developed by Slack to solve some problems the existing systems of the time didn't handle, or didn't handle well. It's the least user friendly, but also the most secure, powerful and gives you the most control. You can define which hosts (or groups) can access which ports on which systems. All nodes are identified with a with a signed certificate and you control the CA and the signing process. In my personal testing it's also performed the best for me. It's even smart enough to find the fastest path between nodes. This is completely free and open source, however to use it you should set up your own "Lighthouse" node with a hosting provider, which will cost you around $5/mo.
