What Are Known Exploited Vulnerabilities?

Known exploited vulnerabilities are vulnerabilities with credible evidence of real-world exploitation. They help security teams move beyond severity-only prioritization and focus remediation on vulnerabilities attackers are actually using.

For a deeper definition, see What Is a Known Exploited Vulnerability?.

Sensor-Led Early Warning

Previdian uses proprietary sensors and private honeypots to observe exploitation attempts, corroborates those signals with vendor advisories and relevant public evidence, and keeps CISA KEV status as context.

Compare with CISA KEV →

Evidence You Can Act On

Each warning can include confidence, evidence links, exploitation status, EPSS, CVSS, CWE, proof-of-concept references, scanner templates, and sensor telemetry where available.

Known Exploited Vulnerability Feed FAQ

How Previdian observes, validates, and delivers early exploitation warnings.

What is a known exploited vulnerability?

A known exploited vulnerability is a CVE with credible evidence that attackers have exploited it in real-world conditions, rather than a vulnerability assessed only through theoretical severity. See also What Is a Known Exploited Vulnerability?.

How does Previdian differ from the CISA KEV Catalog?

CISA KEV is the baseline. Previdian complements it with proprietary sensor and honeypot observations, then corroborates warnings with vendor advisories and relevant public evidence — with confidence and inspectable provenance attached. Browse known exploited vulnerabilities not in CISA KEV or compare with CISA KEV.

What does observed in sensors mean?

It means Previdian honeypots recorded activity associated with exploitation attempts for that vulnerability. Sensor observations complement, rather than replace, the wider evidence and confidence model. Explore live telemetry on Exploitation Signals.

Can teams consume the feed through RSS or an API?

Yes. Previdian provides a free RSS feed, a free JSON feed, and a Pro API for deeper evidence, available telemetry, and integration-oriented workflows. See API & Integrations and API docs.
