Cybersixgill_DVE_Enrichment

By enriching CVEs with the DVE Score, Cortex XSOAR customers gain deeper visibility with relevant threat intel from the deep and dark web with dynamic attributes such as where they are trending, POC exploit details, and more. Loaded with extra-context, this allows users to accurately understand the real impact of CVEs to effectively prioritize critical vulnerabilities.

README

Powered by the broadest automated collection from the deep and dark web, Cybersixgill’s Dynamic Vulnerability Exploit (DVE) Score is a feed of common known vulnerabilities, scored by their probability of getting exploited. The DVE Score feed enables Cortex XSOAR users to track threats from vulnerabilities that others define as irrelevant, but have a higher probability of being exploited. It is the only solution that predicts the immediate risks of a vulnerability based on threat actors’ intent.

DVE Score is also the most comprehensive CVE enrichment solution on the market: Cortex XSOAR users gain unparalleled context and can accelerate threat response and decision making, effectively giving security teams a head start on vulnerability management.

· Anticipate the exploitation of a vulnerability up to 90 days in advance
· Track threats from CVEs that most others define as irrelevant or obsolete, but a higher probability of being exploited by active cyber threat actors.
· Gain visibility as well as the ability to prioritize and articulate the remediation process across the organization - straight from Cortex XSOAR

To obtain access to Cybersixgill DVE Score feed via Cortex XSOAR, please contact Cybersixgill at getstarted@cybersixgill.com.
