We don’t have enough cyber experts to overcome the sheer number of attacks and real compromises we face today. Blocking the correct amount of known threats at the perimeters and boundaries of our clouds and data centers in an automated manner does a few things. First, it dramatically lowers the number of events the rest of our cyber stack has to deal with. Anytime there is a real reduction in events through automation, the efficiency of the rest of your team and technology is increased. Second, assuming a real attack will defeat your sensing, the first you may get indication of an attack is when you have a connection blocked simple because it was a known hostile Internet resource.
