Clarifying Questions (5 mins)

• Looking at Nessus's position in the market, I'm thinking it might be facing increased competition from emerging players. Could you share insights on our current market share and how it's changed over the past year?

Why it matters: Determines if we need to focus on differentiation or doubling down on core strengths. Expected answer: Slight decline in market share due to new entrants. Impact on approach: Would emphasize unique value propositions and cutting-edge features.

• Considering the critical nature of zero-day threats, I'm curious about our current detection rate. What percentage of zero-day vulnerabilities are we currently catching, and how does this compare to industry benchmarks?

Why it matters: Helps quantify the gap we need to close and set realistic improvement targets. Expected answer: Currently detecting about 60% of zero-day threats, slightly below the industry average of 70%. Impact on approach: Would focus on significant algorithmic improvements and potentially exploring AI/ML solutions.

• Given the rapid evolution of cyber threats, I'm wondering about our update frequency. How often do we currently push updates to Nessus, and what's the average time between a new vulnerability being discovered and our system being able to detect it?

Why it matters: Identifies if we need to improve our update mechanism or focus on predictive capabilities. Expected answer: Weekly updates, with an average 3-day lag for new vulnerability detection. Impact on approach: Might explore real-time update systems or predictive modeling to reduce lag time.

• Considering the diverse ecosystem of IT environments, I'm curious about our coverage. What percentage of our users are running Nessus in cloud environments versus on-premises, and are there significant differences in zero-day detection efficacy between these deployments?

Why it matters: Helps determine if we need to tailor our solution for specific environments. Expected answer: 60% cloud, 40% on-premises, with cloud deployments showing 15% better detection rates. Impact on approach: Would consider cloud-native enhancements and ways to bring on-premises performance up to par.
