> Running On-Prem is no safeguard for hacks, and you are trading one set of vulnerabilities for another set. I think the parent poster's point is, concentrating all of these user accounts into one location makes it a more enticing target. Robbing a bank is more enticing than robbing a liquor store. To strech the analogy a bit, and support your point, Banks are better at securing the money. So, to be explicit, in house maybe not as secure as slack, but the possible rewards are just your company's value. If 1000 companies are all in the slack pool, slack ought to be 1000 times better than a single company alone. Because the reward for a hack is so outsized.
