### "Ultimate Defense Upgrade Interesting"

August 24, 2021

4.0

Pros

Seems to have a lot of features which I'm still exploring. However, be careful in blindly accepting its recommendations as it may cause you problems. Fortunately, Tech Support is fast & Excellent if you shoot yourself in the foot as I did.

Cons

Installation is very simple, but the guided setup encourages users to turn on all options without sufficient warning in some areas of things that can go wrong. Not a problem, but recommend any user study the help files to better understand what a module & its settings do BEFORE turning them on/ following the default advice.
