So it works similarly like a honeypot. Petya is no longer considered a new ransomware. I can understand if you say that this product cannot detect a new ransomware of tomorrow but to not able to detect a yesterday ransomware seems strange.It's based on dynamic analysis, but that doesn't mean it will detect all ransomware. It's already failed in some tests by @Av Gurus since it failed to protect against Petya, which is a more sophisticated ransomware threat (than your average) which works by targeting the Master Boot Record.
It seems this product works by placing files around as bait to catch out programs attempting to encrypt the data within these bait test files.
Then do you feel safe having this product on your PC?
