Threats

We focus on applications because your adversaries focus on applications.

Applications have become the focal point of the Internet, the workhorses behind organizations of all types. Attackers have figured this out, and they target applications more than anything else (besides people). This research series ties together trends and data from a number of perspectives to give an overall picture of the application security threat landscape.
