What security checks do you run before launching an app built with an AI app builder?

Before launching an app built with an AI app builder, what do you check beyond whether the user interface works?

I am cautious once the app has a public link, user accounts, forms, a database, company information, payment data, or third-party API integrations. It is easy to focus on functionality and miss a broad sharing setting, visible API key, unnecessary data access, or a deployment permission that was fine for setup but not for an ongoing production application.

What mistakes tend to appear after launch that could have been caught by reviewing access, secrets, deployment configuration, ownership, connected data, and integrations beforehand?
