Jesper Frederiksen, head of EMEA enterprise at Google, said that by pushing an increasing number of services "into the cloud" businesses could tap into the high level of security that exists around large, centralised web-driven datacentres.
"We believe centralising data and workflow processes on highly protected systems is the long-term answer to a lot of issues related to security of data on laptops, protecting highly mobile workers, and keeping end-point security constantly up to date," he said.
Frederiksen will tell attendees of next week's Infosec 2008 exhibition in London that the massive shift to centralised services that is being forecast by analysts will enable all businesses to increase security at a lower cost because of the economies of scale.
"Suppliers of services to millions of users out of shared facilities means they are able to dedicate a lot of resources to security to provide a level of security that is difficult for any individual organisation to produce at a fixed and lower cost than an in-house alternative," he said.
Another benefit of aggregating services and applications in fewer larger datacentres, said Frederiksen, is that this makes it easier to respond to new security threats rather than relying on a security product that needs patches to be distributed to a large number of gateways or end nodes.
Frederiksen denied that this consolidation would make the world's businesses more vulnerable to attack by concentrating critical services and data in fewer locations.
"These datacentres will still be spread geographically, and would be protected by the most advanced and highest level of disaster recovery available that a normal mid-sized business could never afford to maintain on their own," he said.
