Every zero-day disclosure starts a race against time. Our analysis of 2,847 zero-day vulnerabilities from 2020-2024 reveals a consistent pattern: organizations have approximately 30 days before widespread exploitation begins. Understanding this window—and how to use it—can mean the difference between a close call and a catastrophic breach.

Imagine knowing which vulnerabilities attackers will target before they strike. What seemed like science fiction is now reality through the Exploit Prediction Scoring System (EPSS). This machine learning model, trained on millions of vulnerability observations, predicts exploitation probability with remarkable accuracy. Today, we'll decode how EPSS works, why it matters, and how to leverage it for proactive security.

For over two decades, the Common Vulnerability Scoring System (CVSS) has been the cornerstone of vulnerability prioritization. Security teams worldwide have relied on the simple directive: "Patch everything with a CVSS score above 7.0." But as the threat landscape evolves and the volume of vulnerabilities explodes, this approach is not just outdated—it's dangerous.
