Cloud security consists of technologies designed to protect information, data, applications, and infrastructure, but unlike the stacks of appliances that sit at the gateway where they can scan inbound and outbound traffic, cloud security is delivered from the cloud. Cloud security offers many advantages over hardware-based security, especially as users have become mobile and applications have moved to the cloud. It moves security from the network to the cloud, where it can scan all traffic, even if it’s encrypted, no matter where it is headed or where it originated. The cloud also reduces the cost and complexity of deploying and maintaining appliances.
