Do any Banking and Financial institutes use Proxmox?


I’m looking for Banking and Financial Institutes that use Proxmox at production level. It’s for a case study of BFIs using open-source tools.

I don’t know either way, but it strikes me as highly unlikely that a bank would use proxmox. They’re extremely conservative institutions, more likely to still be using actual mainframes designed fifty years ago than to be using a relatively new open source platform which sees considerably more homelab use than even small business use.
