Expel is eliminating the black box within which managed security service providers (MSSPs) operate. You can see and use the same interface their analysts use to deliver their service. There’s no “internal analyst console.” There’s no curtain to look (or hide) behind. With Expel, if you’re ever wondering what they’re doing for you or want to see how they’re making decisions, you can easily look for yourself and see it all.
