ABOUT THIS SITE

How It Works

Our methodology →

We monitor

Once a day at 04:00 UTC, the pipeline pulls ten authoritative security feeds – including CISA advisories – and extracts the day’s most important stories and the CVEs they cite.

We verify

Every CVE is checked against NVD for canonical CVSS and cross-referenced with the CISA KEV catalog. Inline citations link each story to its sources, and a skeptical second AI pass flags – or blocks – claims it can’t substantiate.

You act

Severity is scored from CVSS and confirmed exploitation – not editorial tone – so Critical is rare by design. Structured briefings tell your team exactly what to patch, investigate, or escalate.
