Which of the following does a phishing campaign click rate measure?

A phishing simulation click rate measures user susceptibility to phishing and is therefore primarily an indicator of employee security awareness and behavior . If a simulated phishing message is delivered to employees and a percentage of recipients click the embedded malicious-style link, that percentage provides evidence about how effectively users are recognizing and resisting social-engineering attempts.

NIST research specifically identifies phishing-simulation click rates as a commonly used measure for evaluating the effectiveness of phishing-related security-awareness programs. NIST also cautions that raw click rates should be interpreted in context because phishing messages differ substantially in difficulty; the Phish Scale was developed to provide context for click-rate and report-rate results.

The metric does not primarily measure email-filter effectiveness because a controlled simulation may intentionally bypass or be allowlisted through technical filtering so employee behavior can be evaluated. It is unrelated to data-loss prevention false positives. It also does not directly measure response speed; metrics such as reporting time or mean time to respond would be more appropriate for that purpose.

Therefore, click rate is fundamentally a human-risk and awareness metric .
