Build a defensible monthly exposure metric from public data. One number your CISO can act on.
Every month, Chen walks into a CISO meeting with one number. Not patch rate, not mean time to remediate, not scanner coverage. Those describe the programme. This number describes the threat, and it is built from public data she can defend to a regulator without citing any vendor’s scoring model.
The number is defensible because it is sourced from publicly verifiable facts: CISA’s own catalog and public exploit repositories.
The free tier gives you observable facts. The commercial platform turns those facts into an explainable exposure signal: what changed, why it matters, and what to do next.
