The security market has remained one of the most robust in the face of the worst recession for sixty years maintaining growth when other sectors experienced deep cuts in their rates of expansion.
According to the latest research of the worldwide security market from channel analysts Canalys the last three months of last year saw the sector grow by 10% up on Q3 and 3.6% on 2008.
The worldwide market was worth $3.6bn in Q4 2009 and hardware and software grew with hosted security software emerging as an important slice of the market.
"The release of Windows 7 and the resurgence of the PC market have dramatically helped the client security market, said Nikki Babatola, analyst at Canalys.
"This improvement will likely continue throughout 2010 as businesses role out more computer systems," she added.
In terms of client security vendors Symantec took the top spot with 26.7% market share, followed by McAfee and Trend Micro. On the appliance front Cisco kept its position as the dominant player in the market.
Most of the major vendors have been able to produce financial results that showed they were charting a reasonably safe course through the choppy waters of recession and the RSA show in he US last week was also held in a positive atmosphere.
The theme at RSA was cloud security, which is also expected to feature prominently on the agenda at next month's InfoSec show in London.
