But in practice, most programs still just patch what scores the highest. Risk is inferred, not proven. Fixes are assumed to work. And security teams are left guessing what actually…

Scanning and patching aren't enough. Learn the critical difference between being vulnerable and being exploitable—and why it's the key to preventing real-world breaches.
