Deep Agents don’t add new AI capability, they change the architecture. Planning, memory, filesystem storage, and subagents make agents more powerful but also expand the security surface. Stored content becomes a prompt injection risk, memory spans sessions, and agent handoffs create trust gaps. It’s more observable, but only secure if teams enforce strong controls around tools, storage, and monitoring.
