The training will begin with Tunnel, deploying a fast VPN in Iceland for which 100's of configs can be generated. Then, we'll deploy Fortress, a large dedicated server with cloud, collab docs, webmail, team chat - even a Zoom alternative - tuned & secured using time-tested best-practice strategies

Thanks friend! The optics / light path stuff was really tricky, especially with the gear I had. I enjoyed it so much. Learned a lot!

The threat model is primarily for warrants for data and server seizures, not routes, for which robust transport layer encryption typically provides sufficient cover. Several jurisdictions have proved historically resistant to federal warrants from the US; both Iceland and Switzerland among them.
