Cloud computing's inherent security risks will prevent it from becoming dominant in the enterprise, says Gil Shwed, co-developer of the world's first firewall software.
"Cloud will complement traditional computing, but will not take over," said Shwed, co-founder, chairman and chief executive at Check Point Software Technologies.
Security is about control, and few large enterprises will give up control of business-critical applications until the benefits justify the risk, he said.
Until that point is reached, Shwed predicts larger organisations will adopt cloud computing only for simple functions that can benefit from economies of scale.
Another likely area of adoption is where there is a lack of viable alternatives, as has happened with customer relationship management (CRM).
Businesses are not using CRM in the cloud because is more cost effective or particularly secure, Shwed said.
According to Shwed, the inherent risk of cloud computing is unlikely to disappear because it is not a technological weakness that can be overcome by innovation.
The risk comes from businesses not having control over their own data and being able to account for it if things go wrong, he said.
