Selecting and deploying security technologies such as next generation firewalls or secure web gateways has typically required significant effort, skill, and time. But with widespread shortages of skilled personnel, security teams barely have the resources needed to manage existing security technologies, let alone new ones. To combat this, enterprises turn to security vendors that have built out offerings that leverage the scale and ubiquity of cloud-based infrastructure to deliver over the Internet a wide range of security functionality as a service to enterprises. This approach to deploying security functionality is known as cloud-delivered security.
