It has been predicted that identity and access management (IAM) revenue will reach a worldwide total of $9.9 billion (£6.58 billion) over the next year.
This is according to Gartner, which noted that this will represent an eight per cent increase on 2009's figures of $9.2 billion.
Ruggero Contu, principal research analyst at the organisation, pointed out that although the global economic downturn has had a negative effect on the IAM market, it has proven to be "fairly resilient" and is being given a higher priority than other sectors.
"IAM technology is a critical component of enterprises' security strategies and Gartner clients have indicated that approximately eight per cent of their security budgets are dedicated to IAM," he continued.
Gartner added that by 2013, the IAM market is expected to have expanded by $11.9 billion.
At the end of last month, the firm claimed that although worldwide server shipment revenue fell by 3.2 per cent in the final quarter of last year, shipments grew by 4.5 per cent.
