Network security specialist Palo Alto Networks (PANW) is rapidly climbing the market-share charts, enjoying quick revenue growth as cloud operations drive new network security installations, according to networking hardware purveyor and blogger Brad Reese of Bradreese.com.

Reese, citing industry numbers he attributes to Infonetics.com as circulated in internal Cisco memos, says Palo Alto has moved into the number four market-share position with 7.8% market share among network security vendors in Q3 2014. This makes Palo Alto the fastest growing network security vendor of the year with 17% quarter/quarter growth and 56% growth year/year.

Among other vendors, Fortinet (FTNT) jumped to the number three market-share position, with 8% of total revenue, 7% q/q growth and 25% y/y growth. Rounding out the top of the charts is Checkpoint Software (CHKP) in second place, with 14% of revenue.

Market leader Cisco still leads the pack with 35% share, and in fact it made 4 points of market share gains. Much of this can be attribted to Sourcefire, which contributed $94M in revenue to this number, according to Reese, who is citing Infonetics numbers.
