In this edition of The Motley Fool's "Ask a Fool" series, Motley Fool One analyst Jason Moser takes a question from a Fool reader, who asks: "Recently I was told, 'CLDS (Cloud Security Corp.) may have the Holy Grail in Internet Security' and 'should be a good buy for any investor,' but I don't trust the source. I subscribed to Motley Fool Stock Advisor and Rule Breakers, and I was wondering if you could check this out and tell me if this is a good buy?"
