Why has the average response time for ZeroFox's threat intelligence alerts increased from 10 minutes to 25 minutes in the past week?

Introduction

The recent increase in ZeroFox's threat intelligence alert response time from 10 to 25 minutes is a critical issue that demands immediate attention. This significant degradation in performance could potentially compromise the effectiveness of our threat intelligence system and impact customer satisfaction. I'll approach this problem systematically, focusing on identifying the root cause, validating hypotheses, and developing both short-term fixes and long-term solutions.

Clarifying Questions (3 minutes)

• Given the sudden increase, I'm wondering about recent system changes. Have there been any updates or modifications to the threat intelligence platform in the past week?

Why it matters: Recent changes could directly impact system performance. Expected answer: Yes, a new update was deployed last week. Impact on approach: If confirmed, we'd focus on the update's impact and potential rollback.

• Considering the specific metric, I'm curious about alert volume. Has there been a significant increase in the number of alerts generated recently?

Why it matters: A surge in alerts could overwhelm the system or analysts. Expected answer: Alert volume has increased by 30% in the past week. Impact on approach: We'd investigate the cause of increased alerts and system scalability.

• Thinking about user behavior, have there been any changes in how analysts interact with the system?

Why it matters: Changes in user behavior could affect response times. Expected answer: No significant changes noted in analyst behavior. Impact on approach: We'd shift focus to system-related issues rather than user-related ones.

• Regarding system health, have there been any reported infrastructure issues or outages?

Why it matters: Infrastructure problems could directly impact response times. Expected answer: No major outages, but some intermittent slowdowns reported. Impact on approach: We'd investigate the cause of these slowdowns and their correlation with response times.
