the Cloud is increasingly being used to provide external security testing services (such as AVS, Application Vulnerability Scanning). The argument of the proponents of such services is that security threats come from the cloud, and thus it makes most sense to embed the AVS in the cloud. However after very detailed examination of the options we have come to the conclusion that the Cloud it isn’t necessarily the right answer for many enterprises, and that the AVS service may best be delivered inside the datacenter.
