In April 2026, NIST changed NVD operations to a risk-based model. CVEs still enter the NVD, but many are no longer scheduled for enrichment. For teams that depend on complete coverage, this creates blind spots and slower triage unless enrichment comes from another source.

NIST Updates NVD Operations to Address Record CVE Growth
NIST confirms a risk-based model where many CVEs are no longer scheduled for enrichment.

NIST Enrichment Reductions Impact CVE Coverage, Accuracy
Dark Reading covers Volerion’s research: 1,583 published CVEs left unanalyzed and widespread CVSS scoring disagreements with NIST.
The data layer your program needs
NVD’s cutback pushes enrichment onto your team, whether you’re ready to staff it or not. We take on that work for a fraction of the cost of building it in-house, so your pipeline keeps receiving reliable scoring, mapped products, and meaningful source context.
CVSS 3.1 and CVSS 4.0 vectors
Severity scoring that helps your team prioritize remediation quickly.Dictionary-validated CPEs
Normalized product mappings so affected assets are easier to identify.Categorized reference tagging
Links grouped by source type so analysts can review evidence faster.Context-rich CVE descriptions
Expanded vulnerability context that makes each record more actionable.Our API stays compatible with NVD 2.0 request and response formats, so your existing parsers and workflows keep working. We enrich every CVE and inject the missing context directly into that same schema, so downstream systems receive complete records in the format they already trust.
Keep your established NVD 2.0 request patterns.
Receive enriched CVEs in familiar NVD 2.0 response shapes.
Missing fields are injected so records arrive complete for triage.

FAQ
NVDAPI.com is an NVD API alternative powered by Volerion. It provides NVD 2.0-compatible access to fully enriched CVE records.
We fill the huge gaps the NVD now leaves in CVE data. Every new CVE the NVD defers, usually thousands per week, we enrich ourselves. For every CVE the NVD does enrich, we proxy their data directly for full compatibility and coverage. That makes our API the best drop-in option to swap to.
Records include CVSS 3.1 and 4.0 vectors, validated CPEs, affected versions, improved descriptions, and categorized references.
Most new CVEs are enriched within 10 minutes. Complex or unusually large records can take up to a few hours.
We've spent over 3 years automating CVE enrichment and specializing in standards like CVSS, CPE, and SSVC. During that time, we developed a unique graph-based approach that models each vulnerability as auditable attack paths. Enrichment such as CVSS is then derived from that structured analysis. You can watch our VulnCon26 talk to learn how it works. Our public CISA Vulnrichment corrections also show real examples of us identifying and correcting problems in public vulnerability data.
Yes. Most integrations can keep their existing requests, parsers, and workflows. You only need to change the base URL.
No. NVDAPI.com uses credentials issued by Volerion instead of a NIST NVD API key.
Yes. NVDAPI.com uses a separate production endpoint, reducing your dependency on NVD availability and helping prevent failed synchronization cycles.
Rate limits vary by plan. We offer options for evaluation, regular ingestion, and high-volume production use.
