Nopsec
Vulnerability assessment scanners are adept at finding security flaws, but they leave professionals with chaotic lists of vulnerabilities to sift through. With a mixture of spreadsheets and crossed fingers, cyberdefenders struggle to determine what to fix first. This results in wasted time and little progress made on their overall risk exposure. NopSec has been recognized by both Gartner and Forrester for its whole-brain approach to vulnerability prioritization. We’ve infused our years of offensive security expertise into a patented algorithm that prioritizes vulnerabilities for remediation based on each company’s unique environment. As a result, companies spend less time fixing flaws and proactively improve their risk exposure by scalably addressing what matters most to them.
