Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of enterprise infrastructure security company Fortinet (Nasdaq: FTNT) are getting an 11% boost today after reporting better-than-expected fourth-quarter results.

So what: Fortinet saw growth across the majority of its business segments which led it to beat Wall Street's profit expectations by $0.02 ($0.14 vs. $0.12) and to glide past sales expectations ($120.9 million vs. $116.5 million). These weren't small moves either -- sales popped 29% while profits jumped 27%. These figures also surpassed Fortinet's own guidance of $0.12 and revenue range of $114 million-$116 million that it had given in October.

Now what: There is no such thing as a "safe" area in the technology sector, but I've always believed enterprise infrastructure security could be considered one of the closest things to it. Fortinet has a cash-heavy balance sheet and is growing at a breakneck pace -- I just wish the valuation was more compelling. Despite four consecutive double-digit earnings beats, I just can't recommend buying into a company valued at 50 times forward earnings. I would, however, highly recommend adding Fortinet to your watchlist just in case it drops and its valuation does become more compelling.
