An organization is evaluating the cost of licensing a new solution to prevent ransomware. Which of the following is the most helpful in making this decision?

Single Loss Expectancy (SLE) represents the monetary loss that would be incurred from a single ransomware incident. While useful for understanding individual attack impacts, SLE does not provide a broader annual context needed for evaluating ongoing costs versus benefits, making it less helpful for long-term licensing decisions.

Recovery Time Objective (RTO) indicates the maximum acceptable downtime after a ransomware attack. Although important for operational resilience, RTO does not directly address the financial implications of ransomware incidents, which are critical for evaluating the cost-effectiveness of a licensing decision.

Annual Rate of Occurrence (ARO) estimates how often ransomware incidents are expected to occur within a year. While it contributes to calculating ALE, ARO alone does not provide a complete financial picture necessary for making an informed decision about licensing costs.
