Check security before customers arrive.

The first risk is a privileged key or credential stored where it can be read by someone who should not have it. A secret that grants database or service access can expose more than the interface suggests.

Ask which credentials the product uses, what each one permits and where it is stored. Some services intentionally publish limited client identifiers, so the review should focus on actual privileges and configuration rather than assuming every visible key is equivalent.

The second risk is missing protection for restricted information or actions. A product may have different customer accounts or enterprise roles, but those boundaries need to be enforced where requests are processed.

Ask the reviewer to check whether users can access only the records and operations intended for them. Hiding a control in the interface is not the same as rejecting an unauthorized request. The server should apply the relevant access rules regardless of which screen sent the request.

The third risk is trusting the browser with a decision it should not control. Carlos gives pricing as an example: a technically capable user may manipulate a value if the server accepts it without applying its own rules.

Ask how prices, permissions and other important values are determined. The interface can display information and collect input, but the trusted system should validate the request and calculate the result it is willing to accept.

A useful review goes beyond a statement that the product is secure. Identify the relevant systems, the access each credential grants, the protected actions and the checks used to reject inappropriate requests.

Prioritize findings by their effect on customers and the business. Exposed privileged credentials, cross-account access and manipulable transactions deserve a clear response before wider use. Ask the team to explain the fix and demonstrate how the relevant boundary is verified.
