Patrick Garrity, Security Researcher at Nucleus Security, discusses the rise of vulnerabilities exploitation and threat intelligence in the field of vulnerability management. He highlights the history of vulnerability management, the increase in vulnerabilities and exploitation, the limitations of the common vulnerability scoring system (CVSS), and the emergence of vulnerability threat intelligence. Patrick also emphasizes the importance of open-source intelligence, such as CISA's Known Exploited Vulnerabilities (KEV) List and the Exploit Prediction Scoring System (EPSS), as well as the value of commercial threat intelligence.
