Then someone gets Slack because they don't like Teams, and they think that's worth it. Someone else wants Flowdock. Your new exec used Zoom at his old job and wants everyone to have that for video calling. Your IT security team have half a dozen anti-virus tools, two data loss prevention tools, three monitoring solutions because they're overwhelmed by the amount of data coming out of them. You use a third party RAS solution that doesn't work as well as the one built into Windows, but boy does it add a chunk per-user. You're still running a few JVM applications which you now owe Oracle for the pleasure of using an old JRE. No-one uses the three knowledge management tools you've bought over the years to try and organize your documentation, but you can't decommission any of them yet, because you never migrated everything out of them.

Then someone in the finance team decides the way to tackle out-of-control costs is to buy a tool to monitor installed software on all the desktops. It has another agent.

Welcome to the swamp.
