Separately, TheStreet Ratings team rates INFOBLOX INC as a Sell with a ratings score of D+. TheStreet Ratings Team has this to say about their recommendation:

We rate INFOBLOX INC (BLOX) a SELL. This is driven by some concerns, which we believe should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks we cover. Among the areas we feel are negative, one of the most important has been a generally disappointing historical performance in the stock itself.
