^ It’s legit, as it comes as an optional bundle from Private Firewall which is a trusted vendor ^^
Not saying Good or Bad,
But, you appear to have made a couple of erroneous assumptions here.
Private Firewall may well be a Whitelisted Application.
But neither Private Firewall nor the company behind it PWI Software Inc. appear on the Trusted Vendors List. At least that I can find.
PWI Software Inc. (Private Firewall) and White Sky Inc. (ID Vault) appear to only be partners through a reseller program on the Privacyware website.
No judgments, just observations.
Google Private firewall and you’d know that they are known…
