Score base severity and parse product identifiers quickly.
Tools
Practical utilities for CVE analysis, triage, and blue-team workflow.
These tools are additive to the portal, not a separate product. Use them to score, parse, extract, and normalize the data you already investigate in Vuln Signal.
Pull out IPs, domains, URLs, hashes, emails, and CVEs from pasted text.
Map techniques quickly and inspect phishing-style mail headers in the same workspace.
Normalize dates, inspect certificates, and prettify structured payloads during triage.
Resolve ownership context and inspect SPF, DKIM, and DMARC records from the same toolkit.
Current Tools

Each tool now has its own page so it can grow without turning the Tools section into one giant utility dump.
24 tools available
