🔎 Ever wonder how likely a CVE is to be exploited?

I built a simple serverless tool that checks the risk of any vulnerability using EPSS data, enriched with CVSS context — all in your browser, no backend needed.

Try it → jmousqueton.github.io/epss-cve-loo...

Data Source : @first.org / NIST.gov
EPSS Lookup Tool
Check the real-world risk of any CVE using EPSS and CVSS scores. No backend needed.
