Where I work, we want to move from using and paying for Zscaler, so we have been considering Headscale (vs using/paying for Tailscale). Does anyone have any advice on this and if Tom has a good video to watch on the topic as well?
Thanks in advance!! 
Just went through a bunch of Tom’s videos regarding overlay networks and Netbird has really stood out to me as an option! I really liked this summary video:
Yesh, Netbird is really nice and well done.
I’ve been using self hosted NetBird for a couple months now and have been impressed, hasn’t skipped a beat.
