Guardian Firewall – Guardian Firewall This looks really good. Not cheap, but I am disposed to like a company that says "For the lifetime of our company, Guardian Firewall will utilize a simple tried-and-true business model: Accepting currency for a product that people find valuable. Full stop. We will never track our users. We will never collect personal information about our users. We consider user data to be a liability. Each and every technical design decision is built around that concept. "
