Unified vulnerability data has transformed risk prioritization and optimized remediation effort
The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms. It is helping quite a lot to unify all of that. It also offers good prioritization based on the EPSS or the CVSS score, as well as different other factors including Mandiant threat intelligence and similar aspects. It helps bring it all into one big picture instead of different silos of vulnerabilities. The integrations make my job easier because I can connect my other tools, which is the most important part of this tool to bring in all the vulnerabilities from the different other tools. The prioritization changed it from chasing vulnerabilities or pushing colleagues to patch vulnerabilities to providing colleagues with their vulnerabilities and requesting remediation and patching. Nucleus Security positively impacts my organization by bringing awareness to vulnerability management since we can actually determine how many vulnerabilities we have and how critical the risk is, or we can quantify the risk overall for the company.
