Vulnerability Intelligence & Prioritization
200+ CVEs are published every week. Most of them don't matter to you. ClairSec maps published vulnerabilities to your specific asset inventory and tells your team exactly what to patch, in what order, and why.
What we analyze
We don't just forward the NVD feed. Every CVE is cross-referenced against your asset inventory, enriched with exploitation evidence, and scored for your specific exposure.
- CVE feed (NVD + vendor-direct advisories)
- CVSS re-scoring with exploitation likelihood
- Dark web exploit trading and proof-of-concept releases
- Active exploitation in the wild (CISA KEV, threat actor TTPs)
- Patch availability and deployment complexity assessment
- Supply chain library vulnerabilities (open source dependencies)
- Zero-day intelligence from closed threat actor communities
- Vendor advisories: Microsoft, Cisco, Linux, VMware, Fortinet
- Cloud provider vulnerability disclosures
- ICS/OT vulnerability tracking
- Browser and endpoint software CVEs
- Exploit PoC repositories (GitHub, ExploitDB)
Filter. Map. Prioritize. Not the other way round.
Filter
We ingest the full CVE feed and vendor advisories, then filter against your asset inventory. Only vulnerabilities affecting technology you actually run advance to the next stage.
Score
Each filtered CVE is re-scored using CVSS plus exploitation evidence plus your actual exposure. A theoretical 9.8 in software you don't expose ranks below an actively weaponized 7.2 in your public API.
Prioritize
We deliver a ranked patch list: fix these first, this week, because the exploit is already trading on underground forums. Fix these second. Monitor these. The rest, deprioritize — your team's time is not infinite.
Intelligence deliverables
Weekly patch priority list
A ranked list of CVEs affecting your environment, scored for your actual exposure. Fix these first. Includes patch links and deployment notes.
Dark web exploit alerts
Immediate notification when an exploit for a vulnerability affecting your stack is observed trading in underground forums or published as a proof of concept.
Vendor advisory summaries
Processed vendor advisories for the vendors you run — stripped of marketing language and filtered to what's relevant to your environment.
Monthly vulnerability landscape
Trend analysis, remediation status from the prior period, emerging vulnerability classes, and a forward look at risk in your technology stack.
