Frequently asked questions
- Is this real data?
- Yes — it comes from FIRST's EPSS API and is refreshed on a schedule.
- Does a high score mean a flaw is severe?
- No. EPSS estimates how likely exploitation is, which is a separate question from how damaging it would be. A low-severity flaw can score high, and the reverse.
- Is a key needed?
- No. This source is fully key-less.
- Is it free?
- Yes — free, no download, in your browser.
