Netmaker is legit and backed by Y Combinator. It's based on Wireguard (like Tailscale) and is focused primarily around Kubernetes use. In my opinion, it is a better solution than any other zero trust networking solution due to it offering built in ACLs and traditional Wireguard/VPN features as well as the P2P encrypted mesh overlay.
You may find it easier to work with zerotier or tailscale, but NetMaker is something to keep an eye on. I met the founder at KubeCon last year and he's a really approachable and nice guy. You can always reach out to him directly if you have specific questions or concerns.
