Sophos, a leading cybersecurity company, has dramatically reduced threat investigation times using OpenAI’s Daybreak program. By integrating AI agents into their Managed Detection and Response (MDR) service, Sophos has cut average response times from 38 minutes to just 89 seconds. This transformation offers valuable lessons for beginners building software with AI tools.
How Sophos Uses AI to Scale Cybersecurity
Sophos protects over 625,000 organizations globally, handling trillions of security events daily. Their Fusion system integrates data from 500+ third-party sources, distilling it into 1,000-2,000 cases for investigation. Before Daybreak, each case relied heavily on human expertise, averaging 38 minutes per investigation.
With Daybreak, Sophos built AI agents that automate key steps in the investigation process:
- Investigation Agent: Gathers customer context, threat indicators, and relevant intelligence.
- Planning Model: Creates a plan-execute-review loop for each case.
- Response Agents: Carries out parts of the response based on the investigation.
Tip
AI agents don’t replace human analysts—they handle routine tasks, freeing experts to focus on complex threats and strategic decisions.
The Impact of AI Automation
Sophos' AI-driven approach has delivered significant results:
| Metric | Before Daybreak | After Daybreak | Improvement |
|---|---|---|---|
| Average response time | 38 minutes | 89 seconds | 96% faster |
| Cases resolved end-to-end by AI | 0% | 52% | New capability |
| Compute scaling | Limited by headcount | Scales with compute | More efficient |
These improvements allow Sophos to handle more threats without proportionally increasing their cybersecurity workforce.
Balancing Automation with Human Oversight
Sophos maintains customer control through three operating modes:
- Notify: Sophos investigates and recommends actions, but the customer executes.
- Collaborate: Sophos and the customer work together before taking action.
- Authorize: Sophos can respond directly on the customer’s behalf.
This structure ensures that potentially destructive actions always receive appropriate human oversight, even when AI agents handle routine tasks.
Lessons for Beginners Building with AI
Sophos' success offers several insights for those starting with AI tools:
-
Domain Expertise Matters: Sophos combines OpenAI’s models with their deep cybersecurity knowledge. Similarly, your AI projects will be most effective when you leverage your unique understanding of the problem space.
-
Automate Routine Tasks: Use AI to handle repetitive, time-consuming work, freeing your team to focus on higher-value activities.
-
Maintain Human Oversight: Even as you automate, ensure critical decisions receive appropriate human review.
-
Scale Efficiently: AI can help you handle increasing workloads without proportionally increasing costs.
What's Next for Sophos and AI Cybersecurity
Sophos plans to expand their AI agents' capabilities, addressing more use cases and refining their response processes. Their approach highlights the importance of staying ahead in cybersecurity, where attackers increasingly leverage AI tools.
Important
While AI accelerates defense, it also empowers attackers. A layered security approach—including endpoint protection, multifactor authentication, and network segmentation—remains essential.
