Field Notes

Heatmaps to Histograms: Field Notes, a free newsletter on cyber risk quantification. New subscribers get Chapter 5 of the book.


Join Heatmaps to Histograms: Field Notes and your welcome email includes Chapter 5 of the book, Your First Quantitative Risk Assessment, free. It’s the chapter where you build a Monte Carlo simulation in Excel and run a complete risk analysis, start to finish.

After that, each issue carries a practical technique, a case study from the field, and a tool or prompt you can use the same day. It covers the parts of cyber risk quantification that are hard to get from a framework document: how to scope a scenario someone will argue with, how to get a usable estimate out of an engineer who says “it depends,” how to present a loss exceedance curve to a board without losing the room, and what to do when the data you wanted doesn’t exist.
