Separating the Signal from the Noise: How Mandiant Intelligence Rates Vulnerabilities

Every information security practitioner knows that patching vulnerabilities is one of the first steps towards a healthy and well-maintained organization. But with thousands of vulnerabilities disclosed each year and media hype about the newest “branded” vulnerability on the news, it’s hard to know where to start.

The National Vulnerability Database (NVD) considers a range of factors that are fed into an automated process to arrive at a score for CVSSv3. Mandiant Threat Intelligence takes a different approach, drawing on the insight and experience of our analysts.

We also believe that limiting ‘critical’ and ‘high’ designations helps security teams to effectively focus attention on the most dangerous vulnerabilities.
