Revenue from
security applications delivered as a
cloud-based service will
triple in some markets, according to
analyst Gartner.
In
messaging security controls - such as malware and spam
detection/exclusion for e-mail and instant messaging - cloud-based
services account for 20% of of the sector's revenue in 2008, said
Gartner.
By 2013, cloud-based services in messaging security controls
will account for 60% of revenue, Gartner said.
Cloud computing will enable security controls and functions to
be delivered in new ways and by new types of service providers.
It will also enable enterprises to use security technologies and
techniques that are not otherwise cost-effective, said the
analyst.
Gartner
defines cloud computing as a style of computing where massively
scalable IT-related capabilities are provided "as a service" using
internet technologies to multiple external customers.
