In traffic we could see that 12% of the company used the site daily, transferring gigabytes of data between our engineers and contractors.
I asked why we didn't just start paying WeTransfer since it's so widely used and this would solve the problem, too.
They said they should just use the internal SharePoint file sharing tool.
I asked how this would work since most of WeTransfer use was us receiving docs, not sharing them.
They said the contractors should just update their policy, and that was the end of the debate.
Last time I spoke to a field engineer he said they mostly use private mailboxes now mostly since they "can't even copy something in Outlook anymore" on company laptops.
I decided not to report this to CISO and these docs are workorders and pictures demonstrating workorders have been completed. They're irrelevant one day later.
