Imaging Bob from accounting pasted a customer's SSN into a chat thread, group or 1:1... there countless things that shouldn't be posted in chat messages to live for eternity.

Some companies build it into their systems to automatically catch and mask that data, sometimes someone has to rollup their sleeves and do it manually.

I'd wager that 95%+ of orgs have tons of sensitive customer data scattered into chat messages in Slack, Teams, Hangouts, etc that would horrify most of us here.
