Privacy and limitations: Some checks run locally. Some use bounded server lookups. Do not paste secrets, credentials, private logs, or internal asset inventories unless the selected tool clearly explains how the data is handled and you have permission to use it.
Check
Check a security artifact
Start with a CVE, domain, email header, token, certificate, or other security artifact. Vuln Signal points you to the right tool or reference without making unsupported claims.

What do you want to check?
Type one artifact or choose a type below. This launcher routes your entry in the browser without intentional persistent storage.
Ready
Enter an artifact to get a safe starting point.
Exact CVEs open CVE detail. Domains point to domain and DNS checks. Tokens, headers, records, certificates, logs, and detection rules point to focused local tools or references.

These are shortcuts to existing routes. They do not create a new workflow or change the global site structure.
CVE or vulnerabilityLook up public vulnerability context and source confidence.
Domain or websiteCheck DNS, TLS, headers, and website posture tools.
Email authenticationReview SPF, DKIM, DMARC, and spoofing protection.
Email headerInspect authentication results and sender evidence.
Token or certificateInspect JWTs locally or review certificate/TLS helpers.
Log or detection ruleExtract indicators, draft Sigma/YARA, or normalize signals.
Report or handoffTurn validated evidence into owner-ready language.
