> Maybe that's actually what Hack the Box is, mentioned in the sibling Hack the Box hosts the VM for you on their servers (and you connect to a VPN to get access), but it's effectively that. They release a box every so often (roughly monthly?) and users compete to collect the user/root flags. They also have a rotating selection of past boxes (and I think you get access to all of them if you pay them), so it's kind of like an "on demand" CTF.
