April 23, 2012 – Gartner reports that global unified threat management (UTM) revenue reached $1.2 billion in 2011, a 19.6% increase over 2010.  Fortinet remained the top vendor in revenue in 2011, accounting for 20% of the market, followed by SonicWALL (which was acquired by Dell for $1.2 billion last month) in second place with 13%, Juniper Networks  in third with 12%, Check Point Software and Watch Guard were tied for fourth with 11% and Cisco in fifth with 9%. Sophos, SECUI, Cyberoam, and Barracuda Networks followed. North America was reportedly the largest market for UTM products which the reports says was related to, ”strong payment card industry demand requiring both firewalls and intrusion prevention technologies in midsize businesses with higher credit card transaction volumes and greater interest to protect against network-based attacks.”
