The key idea is to assess data security impact by looking at how many customers were affected. When comparing companies, you want the highest disclosed count of affected customers within the same reporting period and with the same scope, because that figure best illustrates the breadth of impact from the breaches. A larger number signals greater reach, which can drive higher remediation costs, potential regulatory scrutiny, and reputational risk for stakeholders. Keep in mind that the numbers must be comparable: the metric might be stated as customers affected or records exposed, and you need to ensure consistent definitions and deduplication across multiple incidents. If a company has a huge customer base, even a breach with a small percentage could still affect a large absolute number, so focus on the actual counts and consistent scope rather than percentages alone. Therefore, the option with the largest number of affected customers represents the greatest breach impact.
