Email, billing, and access: where founders often get exposed

The attack can look like normal support

Not every risk starts in code. In small SaaS, many decisions happen through email, WhatsApp, support, and admin panels. An urgent request can become a bank change, a wrong invite, or an access change.

The point is not to distrust every customer. It is to confirm sensitive actions.

Watch these flows

• Bank or payment destination change.
• Admin invite outside the normal flow.
• MFA reset or email change without enough validation.
• Manual billing link without internal record.
• Support asking for personal data it does not need.

Commercial security does not need to be heavy. It needs to stop speed and improvisation from becoming unauthorized access.
