Tailscale makes Aperture available for free, and while it's not something you own, it is in your tailnet, so at least you have a certain amount of control over how things access it. It gives a nice view of what agents are doing, with lots of configurability and extensions, and the team behind it has been updating pretty steadily.

I happen to be working on an extension to Aperture, so I have my own reason to promote it. But I do think it's a nice easy solution, and I promoted it to people before I was extending it.
