The Cyber Exposure Score: How Secure Is the Business?

“By 2022 cybersecurity ratings will become as important as credit ratings when assessing the risk of existing and new business relationships.”

– Gartner¹

Tenable Lumin enables organizations to effectively measure and benchmark their cyber exposure, providing comparisons both internally (e.g., business groups, geographies, asset classes) and externally against peer organizations.

The Cyber Exposure Score, a critical component of Tenable Lumin, is an objective rating of cyber risk derived through data science–based measurement. The score is automatically generated daily through machine-learning algorithms that combine vulnerability data with other risk indicators such as threat intelligence and asset criticality. Today, the score is calculated by combining the Tenable Vulnerability Priority Rating (VPR), for the likelihood of exploitability, with the Tenable Asset Criticality Rating (ACR), for the business criticality of the affected asset.

The Cyber Exposure Score can be applied to a single asset, a group of assets or an entire organization.
