Who is the Ponemon Institute, and why is its "Cost of a Data Breach" research widely cited in security business cases?

The Ponemon Institute (founded 2002) is an independent research organization focused on information and privacy management; its annual breach-cost study gives security teams credible, comparable money figures.

The cited edition examined 600 organizations across 16 countries and 17 industries (breaches ranging from 2,960 to 113,620 compromised records) and interviewed 3,470 security and C-suite leaders with first-hand knowledge of the incidents, costing each breach across the full lifecycle. WHY it matters for a CISO: boards respond to euros, not to abstract "risk". A respected, independent dollar figure — e.g. an average breach cost — converts a technical worry into a number an executive can weigh against the cost of a control. It is the kind of evidence that wins budget.
