Gartner is predicting that corporate spending across the world for a broad swath of security services will climb from about $35 billion today to $49 billion (£31 million)in three years, with the managed security services expected to jump most of all.

Managed security services called "IT management" will grow from about $8 billion today to $14.8 billion in 2015. Other segments, such as security consulting, are also expected to thrive, with consulting rising from $9.6 billion today to $12.1 billion in 2015.

Gartner research director Lawrence Pingree predicted telecommunications providers will continue to be among the larger players in managed security services around the world, which hit $6.87 billion last year.

Factors such as desire to economise and the difficulty in establishing round-the-clock personnel coverage for security will continue to drive corporate adoption of managed security services but it's the small-to-mid-sized companies that are exhibiting demand in particular now, Pingree says.

The North American security services market is expected to surpass $14.6 billion next year and grow to $19 billion in 2015. Western Europe is projected to reach $11.9 billion next year and $14.4 billion in 2015. The Asia/Pacific region is forecast to reach $4.7 billion in 2012 and total $7 billion in 2015.
