Security guarantee? Good one. Tell them to get in line for a unicorn ride.
Guarantees are for appliances. We're deploying complex, networked code that interacts with unpredictable systems. Every new plugin, API, or prompt is a new attack surface. You can have monitoring, you can have controls, you can have layers of isolation. But a guarantee? That's just asking to be on a future breach report.
What they probably want is a checkbox to make a problem go away. Break it down for them. Show them the actual risks: prompt injection, data exfiltration, privilege escalation in the orchestration layer, dependency poisoning. Ask them which one they'd like us to "guarantee" won't happen. Watch them backpedal.
