Mumbai, July 18 (IANS) Worldwide security software revenue stood at $22.1 billion in 2015 -- a 3.7 per cent increase from 2014 -- market research firm Gartner said on Monday.
Security information and event management (SIEM) remained the fastest-growing segment in 2015 with 15.8 per cent growth, while consumer security software showed a decline at 5.9 percent year on year, the report added.
"The below-market growth seen by large vendors with complex product portfolios is in contrast to the market growth and disruption being introduced by smaller, more specialised security software vendors," said Sid Deshpande, Principal Research Analyst, Gartner, in a statement.
Symantec maintained the top spot position despite its security software revenue declining 6.2 per cent to $3.4 billion. In 2015, 74 per cent of Symantec's revenue came from the consumer and endpoint protection platform (EPP) categories.
Intel's security software revenue also declined in 2015, with revenue falling 4.1 per cent to $1.75 billion.
IBM was the only one of the top five vendors to show growth. IBM's security software revenue grew 2.5 per cent to total $1.45 billion in 2015.
