Fortinet very well positioned in much in demand security space
Based on Fortinet's product mix and very good ratings in Gartner Magic Quadrant for UTM providers (leader in leader Quadrant) I think they are the best positioned Security company for growth or to be acquired at a very good premium.
With Cisco acquiring SourceFire recently it just proves the value of security in today's very active Cyber Security environment. Most analysts are listing Fortinet as a top target. PANW and IMPV are also good companies in this space as well but Fortinet seems the most likely.
The Cyber Crime environment has never been more active and it is growing at huge rates, thus the need for companies to protect their assets. Fortinet has a very good product mix for this and are highly rated.
I do not expect it will take long for the market to reward Fortinet in coming months and rest of year and next year as spending on security continues to increase.
I also think they will be bought out soon (within 6 months or 1 year etc.). They are a strong player in the UTM security space and seem to be building some nice new larger customer deployments etc.. I would think the price could be in the $30 to $40 range possibly.
