Cisco’s (Nasdaq:CSCO) Network Security Continues to Grow

Most people don't think of network security when they think of Cisco (Nasdaq:CSCO), but it has been growing solidly since 2005, when it generated close to $1.1 billion in revenue, to 2009, when it generated $1.9 billion.

while those numbers are earth-shaking, they do lay a solid foundation for a segment of the market that's starting to grow quickly.

Think of Wikileaks to understand why protecting data is so important, and increasingly on the minds of executives.

In 2010 Cisco generated $2.2 billion in revenue via its network security products.

The overall network security market is estimated to grow to $8.2 billion in 2011, a jump of about 8 percent from 2010.

Network security accounts for under 10 percent of the share price of Cisco, so isn't a huge game change, but is an important piece of the overall picture to consider with the company.
