• Looking at the timing, I'm thinking there might be a seasonal component. Has this increase coincided with any particular events or time of year?

Why it matters: Seasonal patterns could explain cyclical changes in false positive rates. Expected answer: No clear seasonal pattern identified. Impact on approach: If seasonal, we'd focus on adjusting algorithms for time-based factors.

• Considering the magnitude of the change, I'm wondering if there have been any recent updates to the threat detection algorithms. Have there been any significant changes to the Managed Risk service in the past quarter?

Why it matters: Recent changes could directly impact false positive rates. Expected answer: A minor update was implemented two months ago. Impact on approach: If confirmed, we'd prioritize reviewing and potentially rolling back recent changes.

• Given the specificity of the 30% increase, I'm curious about the baseline. What was the average false positive rate before this increase?

Why it matters: Understanding the baseline helps contextualize the severity of the increase. Expected answer: The previous false positive rate was around 5%. Impact on approach: A low baseline would make this increase more concerning and urgent to address.

• Thinking about user segments, I'm wondering if this increase is uniform across all clients. Have we seen any patterns in terms of which types of clients or industries are experiencing higher false positive rates?

Why it matters: Segmentation could reveal targeted issues or vulnerabilities. Expected answer: The increase appears to be more pronounced in the financial sector. Impact on approach: If sector-specific, we'd focus on tailoring solutions for affected industries.
