How Do I Know Safebox Really Protects My Transactions?

Dear Sirs:

I have been using Bitdefender for a couple of years.

One module I use frequently is "Safepay"

It is said it has sandbox technology.

It is said it protects transactions.

Great.

How do I know it is true?

Are there tests that show how good is "Safepay"?

If you look at the Internet, there are papers that say sandbox technology does not protect, as well as other papers that say it does protect.

What is the truth?

The best way to demonstrate who is right is showing numbres, cases, tests.

Regards.
