1. Purpose of the gate
Security concept approval decides whether the security the product's markets expect is accepted as part of the product concept and funded. It is the first point at which security has a named owner and a budget, so it stops security being treated as a feature to add later.
The gate does not judge the security design; none exists yet. It judges whether the expectations are understood well enough to fund the definition work: which markets, which customers, which kinds of assets and attackers, and which certifications or regulations are likely to matter.
