The way I deal with this at work is: we both work for a person who can fire us for looking at them funny. The threat of dismissal is sufficient for us to expect our peers to be rude neighbors but not criminal ones. If the divisions get big enough that this gets blurry, well then it’s simple enough to ask for private VMs/separate Kube clusters. The Conway’s Law aspects of server maintenance cycles when you report to separate directors/VPs is self evident.
And of course collocating different classes of work can lead to a bug in a low priority task taking down a high priority one. So those also shouldn’t run in the same partition. Once you’ve taken both of those into account, you’ve already added some security in depth. It’s hard even to escalate a remote exploit into a privilege escalation into attacking a more lucrative neighbor.
