> Firstly, employees need to be aware that they are not allowed to use this software and you need to therefore provide a solution.
As far as I understand, the usage of such tools is caused by the need to accomplish some goal that they don't know how to otherwise do. Therefore, wouldn't it be a good idea to self-host such a tool, even if it's not a part of any pre-existing platform that's in use for other business processes?
For example, for various data format related concerns, I've seen CyberChef be pretty good: https://github.com/gchq/CyberChef
As for some binary file format conversations, HRConvert2 seems viable: https://github.com/zelon88/HRConvert2
If self-hosting things is too much of a bother/risk, then I guess all that's left is local tools, such as Handbrake on Windows for video: https://handbrake.fr/ and maybe something like XnView for images: https://www.xnview.com/en/ and so on...
But then there's the risks of self-hosted or local software containing something malicious and needing to be audited etc. I recall that in my previous org, I helped develop a Wiki page listing many of the tools available within the company internally, so that anyone who needs to store files could immediately look at self-hosted Nextcloud (for example), as opposed to going for Dropbox or whatever. Of course, instructions alone probably aren't enough, restrictions are also necessary, but discoverability is always good!
