Live AMA with Sophos CTO John Peterson: AI, the agentic SOC, and the technology decisions behind building (and defending against) frontier AI - June 23, 2026
Hi r/sophos 👋
We're live. I'm John Peterson, CTO at r/sophos , here to take your questions on AI, the agentic SOC, and the engineering decisions behind how we're building (and defending against) frontier AI.
Drop them below - we'll be responding in real time.
⏰ Live Response Window
- Tuesday, June 23
- 13:00–15:00 BST | 08:00–10:00 EDT | 12:00–14:00 UTC
- I'll circle back to additional questions over the following 24 hours
💬 What to ask
- What an agentic SOC actually looks like once it's running real workflows
- Securing the AI footprint enterprises are rapidly building (copilots, agents, model APIs, MCP servers), and where the biggest risks are showing up
- Human-in-the-loop, human-on-the-loop, and where those models actually hold up in production
- The engineering trade-offs of building AI-driven security, including what didn't work
📌 A few housekeeping notes
- Keep questions focused on cybersecurity and AI
- Don’t share sensitive configuration or environment details
- This is a discussion, not a support session, but i aim to be as helpful as possible and if it’s related to my world, i'm happy to help with any issues you may be having. If not i can triage you to our support function or the correct team
- Be respectful, even when you disagree
Let's get into it.
