KEV Intelligence is becoming Previdian.

Exploitation intelligence

Observed Exploitation Signals

Sensor-backed exploitation attempts against internet-facing services, mapped to vulnerabilities and reviewed for confidence. See where attacker activity is concentrating before severity scores alone tell the story.
