Every product changes from one release to the next, and a comparison of named vendors is out of date the day it is published. The underlying approaches change far more slowly — and they decide most of what your project will feel like: how many systems you validate, how many audit trails an inspector will ask about, and how long it takes to go live.
These comparisons describe general approaches in the market, not any specific vendor or product. Statements about Swat iQua Suite are our own; statements about other approaches describe what is typical and may not apply to every product.
