Frost & Sullivan vulnerability tracker is compiled from various public sources to analyze the vulnerability landscape from 2000 to the present. The US CERT is the primary source of data but other sources include the National Vulnerability Database as well as news and vendor websites. The top research companies are also interviewed to provide industry and technology trends. The data is collected, queried, and segmented, resulting in a wealth of information that is intended to provide qualitative commentary on the research industry and to recognize the most prolific disclosers of vulnerability reports. This research service includes bugs reported by security vendors and research/testing labs such as iDefense, TippingPoint, and Secunia.
