Cloud access security brokers (CASBs) are central data authentication and encryption hubs for everything your enterprise uses. They have become especially important as more enterprises allow personal phones and other unmanaged devices onto their networks. Forrester predicts that by 2022, 60% of large enterprises will use CASBs, up from 20% that used them at the end of 2018. CASBs have evolved to be just as important as firewalls once were back in the day when PCs were being bought by the truckloads.”]
