Coverage
Partialpublic feeds are useful but not exhaustiveKnown Limitations
Know what the portal cannot guarantee before you act.
This page collects the practical limits of public-source coverage, local browser state, generated tool output, and live-derived vulnerability views.

Common places where users can overread the site
Coverage is not universal
The portal may not include every CVE, vendor advisory, exploit note, package update, private disclosure, or regional source.
Freshness can change
A page can render successfully while an upstream feed is stale, cached, degraded, unavailable, filtered empty, or missing structured fields.
Source confidence is not truth
Confidence labels help pace validation. They do not prove local exposure, compromise, remediation, business impact, or vendor intent.
Threat views are derived
Maps, actors, ransomware relevance, exploit-chain views, and campaign cards are orientation layers, not live packet telemetry or incident evidence.
Tools produce starting points
IOC extraction, Sigma, YARA, hunt, regex, CVSS, and exposure outputs need field checks, false-positive review, owner validation, and scope control.
Local browser state is not a system of record
Saved items, notes, compare queues, and exports are helpful working aids. Formal approvals and closure evidence belong in official systems.
Safe posture: use Vuln Signal to decide what to validate next. Use vendor sources, asset inventory, telemetry, change records, and owner evidence to decide what is true locally.
