The global security software market is on the rise, with analyst firm Gartner reporting a 3.7% increase for 2015, despite large vendors such as Symantec and Intel experiencing below-market growth. According to Gartner, security information and event management remained the fastest-growing segment in 2015, with 15.8% growth, while consumer security software showed the sharpest decline at 5.9% year on year. In 2015, the top five vendors together accounted for 37.6% of the security software revenue market share, down 3.1 percentage points from 2014. These vendors also displayed a collective decline of 4.2% in 2015, while the rest of the market (Others) grew strongly at 9.2%year on year, Gartner's analysis shows. "The below-market growth seen by these large vendors with complex product portfolios is in contrast to the market growth and disruption being introduced by smaller, more specialised security software vendors," explains Sid Deshpande, principal research analyst at Gartner.
