everyone assumed:

defaults are safe defaults

what was actually true:

A default is a decision the vendor made for you, and it is not always the safe one.

what everyone assumed

A default from a major vendor feels like a recommendation, a safe baseline chosen by people who know better. The assumption is that out-of-the-box settings protect you until you deliberately open them.

what happened

Where administrators had not explicitly locked permissions and had enabled a data feed, anonymous users could read the underlying records straight through the interface. Many organizations never changed the setting, because it looked like it was already safe, and the vendor initially described the behavior as intended.

how it surfaced

In 2021 researchers found 38 million records exposed across 47 organizations through this default, including contact-tracing data, Social Security numbers, and employee IDs, across government and major companies.

A default is a decision the vendor made for you, and it is not always the safe one.

Out of the box can mean open, and assuming otherwise is how millions of records sit exposed in plain configuration.

your turn

what you can do about it

  1. this week

    Pick one SaaS or low-code platform and review the defaults you never changed.

    Your SaaS and low-code platforms ship with defaults you have probably never reviewed, some of which favor convenience or visibility over protection. Power Apps is the reminder that out of the box is not the same as secure. Which of your platforms' defaults you have actually checked is the gap it exposes.
