Tenable.io correlates vulnerability severity with asset criticality scores, surfacing the top 3% of vulnerabilities that pose real risk versus thousands of theoretical findings.
Tenable Identity Exposure maps Active Directory misconfigurations to known attack paths like AS-REP Roasting, showing how attackers could escalate from a standard user to Domain Admin.
