Schneier: Many security products offered the feeling of being secure rather than actual security

Bruce Schneier told delegates at the RSA security conference in London that "For every supplier with a good product or service, there is at least one more out to make a quick buck before customers find out"

The over statement of particular types of threats and the use of your heart i.e a hunch rather than your head can result in the wrong product being selected. Even when the right product is bought the use of default or minimal configuration means that the product is not performing its role properly and the user has a false sense of security.
