We built Signal to not know things. Agents want to know everything.

The agentic Internet runs on data access — every tool call, trace, and log an agent touches becomes a new surface for leakage and surveillance. Signal took the opposite bet: sealed sender, minimal logs, no contact graphs. Data we never collect can’t leak, be subpoenaed, or stolen. This talk, designed for security leaders and practitioners, maps those lessons onto autonomous systems: where agent metadata concentrates, why tool-call histories are the new metadata goldmine, and three design principles for building useful agents under data minimization. You’ll leave with a checklist for shrinking what your agents can see — and a harder question about what “secure” means when the software acts on its own.
