The Business Value of Security
summary
Makes a concrete claim: replace fuzzy severity labels with numbers and you can prioritize fixes by business impact. Uses Monte Carlo simulation implemented in Python or Excel (mentions a Streamlit uploader), produces a loss exceedance curve and overlays a risk tolerance line, measures forecast quality with the Brier score, and cites scale: ~25,000 disclosed vulnerabilities/year and 0.5% critical → ~125 triage candidates. Recommends automating runs and sharing the numeric security matrix.
