What is Kenna Security?

Kenna Security (now part of Cisco) was a risk-based vulnerability management platform. It aggregated vulnerability data from various sources, including vulnerability scanners and threat intelligence feeds, to prioritize remediation efforts based on actual risk. Kenna used data science and machine learning to identify which vulnerabilities posed the greatest threat to an organization, helping security teams focus their resources on the most critical issues. It was commonly used by security teams to improve their vulnerability management programs, reduce their attack surface, and measure the effectiveness of their remediation efforts.
