This is an example of bad promotional material -- there are good reasons to use external security service, but the post does not show them. Instead, it is trying to scare people into getting the service, by listing reasons which apply to external product as well. You are going to have "bus factor" with outsourced security as well. You will need local integration expert (or a team of them) to support the local developers. You still have to worry about scaling, but this time from financial endpoint.
