TL;DR: Zero-day exploitation can begin before disclosure, leaving scans behind, according to Anchore. SBOM and vulnerability records need to be current enough to answer exposure questions before the response window closes.
Editorial analysis by NHI Mgmt Group, based on content published by Anchore: “What Your Vulnerability Scan Misses The Moment a Zero-Day Drops”.
By the numbers:
- CrowdStrike's 2026 Global Threat Report found that 42% of vulnerabilities were exploited before public disclosure, according to Anchore.
Key questions
Q: Why do zero-day vulnerabilities create such high operational risk for defenders?
A: Zero-days compress the defender's timeline because attackers can act before a patch exists or before change control can complete.
Q: What breaks when teams rely on a new scan to confirm zero-day exposure?
A: The workflow can fail because the scan finishes after attackers have already had a usable window.
Q: What should teams do first when a zero-day is disclosed before scanning can finish?
A: Start with the most current inventory data you already trust, then query that inventory for the affected CVE, package, or version.
Practitioner guidance
- Validate vulnerability feed freshness Check the Data Service Build Time field before trusting any zero-day query result, because stale feeds turn a fast answer into a misleading one.
- Query stored SBOM inventory first Use vulnerability ID lookups and package-version searches against stored SBOM data before triggering a fresh scan, especially when disclosure and exploitation overlap.
- Add package-level zero-day checks Search by package name and version when a CVE record is missing or delayed, so newly exposed components are still identified during the early advisory window.
Bottom line: Zero-day response now depends on how quickly teams can query exposure, not how quickly they can launch a fresh scan.

Zero-day readiness is now an inventory governance problem, not a scan scheduling problem. When the exploit window closes before the patch cycle opens, the control that matters is the freshness and queryability of your software inventory. That shifts operational ownership toward data integrity, feed currency, and fast matching across fleets. The practical conclusion is that teams should measure how quickly they can answer "are we affected" without running a new scan.
A few things that frame the scale:
- Vulnerability exploitation accounts for 32% of initial infections in Mandiant’s 2026 M-Trends report.
A question worth separating out:
Q: How should organisations compare SBOM queries with vulnerability scans for zero-day response?
A: Use SBOM queries for rapid exposure confirmation and scans for complementary validation, not as interchangeable steps. SBOM queries answer whether known software versions exist in your estate right now, while scans still help confirm broader environment context. The practical difference is speed of triage versus depth of verification.
