I'm looking into vpn tunnels and how safe and reliable are they. I've seen a few but I'm not so sure

I’ve recently seen tailscale which is a good one apparently but I’m a little skeptical on what they do if I would route through them. I have a file server and a game server that I want to route through but I’m nit so sure how safe I will be l. I’ve also seen netgear vpn and thought that might be a great idea because I can see traffic and block if I need to. I’m essentially looking for a great alternative to portforwading that keeps me safe and dosnt mine data.
