A real business has more to protect than a prototype does: customer information, employee access, contractual commitments, internal knowledge, and the reputation it is building.
Every deployment should define what data the system can use, who can access it, where it is stored, how long it is retained, and what activity can be audited. Company data should not quietly become training material for someone else's model.
Security and governance are part of the system design from the beginning. They should be proportionate to the workflow, understandable to the owner, and strong enough for the responsibilities the company already carries.
