CommunicateCyber Risk

Continuous Visibility

Cyber ExposureMetric

PrioritizeExposure

LiveDiscovery

MeasuringCyberExposureLeveragesVulnerability Management

Accurately represent and communicate cyber risk to the business – in

business terms

Continuous Visibility into where an asset is

secure, or exposed, and to what extent

Apply Cyber Exposure data as a key risk metric

for strategic decision support

Add context to the exposure to prioritize

and select the appropriate remediation

technique

Live Discovery of every modern asset

across any computing

“Modern applications are largely assembled, not developed, and developers often download and use known vulnerable open-source components and frameworks.”

-Gartner

“Even if Docker certifies an app as being safe and effective, I'm not risking $11 billion on Docker telling me it's safe. We need extra assurance and to prove it to ourselves.”
