Critical vulnerabilities and CVEs
How to prioritize risks with public NVD and CISA KEV data — volume, severity and what really matters to defend.
What is a CVE and why volume matters
CVE (Common Vulnerabilities and Exposures) is a unique identifier for each known security vulnerability, published by NIST's NVD (National Vulnerability Database). Each CVE includes a CVSS (Common Vulnerability Scoring System) score from 0 to 10 indicating severity.

CISA KEV: the list that really matters
CISA (Cybersecurity and Infrastructure Security Agency) maintains the Known Exploited Vulnerabilities (KEV) catalog — a list of CVEs with confirmed active exploitation in the field. While NVD lists all known CVEs, KEV lists only those attackers are already actively using. It is the highest priority list.
- 1. CISA KEV first — requires immediate remediation if the system is exposed.
- 2. CVSS ≥ 9.0 in internet-facing systems — critical with high attack visibility.
- 3. CVSS 7.0–8.9 in systems with sensitive data — high contextual risk.
- 4. CVEs ≤ 6.9 in isolated systems — remediate in normal patch management cycle.
