Tenable Predicts the Big Bad 3% of Vulnerabilities

February 11, 2019 / Jessica Lyons Hardcastle

Security teams found 16,500 new vulnerabilities in 2018, according to Tenable. Obviously, that’s way too many for most — if not all — organizations to wrap their arms around. The “good” news is that just 7 percent of these had a public exploit available, and Tenable estimates only 3 percent of vulnerabilities will be exploited. If only there was a way to figure out which ones are in that 3 percent…wait for it…Tenable says it developed a new tool that helps companies do just that. It’s called Predictive Prioritization, and it analyzes Tenable vulnerability data combined with third-party vulnerability data and threat intelligence across 150 data sources. It then uses a proprietary machine learning algorithm to predict the likelihood a vulnerability will be exploited in the next 28 days. Predictive Prioritization also calculates a vulnerability priority rating, which automatically indicates the remediation priority for each vulnerability. ...
