When conducting experiments, scientists will carefully set up control measures to provide parameters for results. These controls help define the outcome by marking what ways the experiment did or did not meet expectations.

This guide below will lay out in detail the difference between the pros and cons of penetration tests and vulnerability assessments, their differences, and why you might choose one or the other.
