Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the detection algorithm. Has there been any recent update to the Vulnerability Detection module?

Why it matters: Recent changes often correlate with performance shifts. Expected answer: Yes, there was an update last month. Impact on approach: If confirmed, we'd focus on the changes made in the update.

• Considering user segments, I'm wondering if this issue is affecting all customers equally. Are we seeing the increased false positive rate across all customer types or is it concentrated in specific segments?

Why it matters: Helps narrow down potential causes and prioritize solutions. Expected answer: The issue is more prevalent in enterprise customers. Impact on approach: We'd investigate enterprise-specific factors or configurations.

• Given the nature of vulnerability detection, I'm curious about any changes in the threat landscape. Have there been any significant new vulnerabilities or exploit techniques discovered recently?

Why it matters: External factors could be influencing our detection accuracy. Expected answer: No major new vulnerabilities have been reported. Impact on approach: We'd focus more on internal factors if external threats haven't changed significantly.

• Thinking about data sources, I'm wondering if there have been any changes to our vulnerability databases or feeds. Have we added any new data sources or made changes to existing ones?

Why it matters: Data quality and consistency are crucial for accurate detection. Expected answer: A new vulnerability feed was integrated last month. Impact on approach: We'd investigate the integration and quality of the new data source.
