Most UK businesses (71%) think security is the biggest threat to cloud computing, a survey of IT chiefs has found.
Most organisations would like to enable remote working, but security concerns is still a stumbling block, said Steve Watts, co-founder of authentication firm SecurEnvoy which conducted the survey.
Over three quarters of the respondents said they would be concerned if their company's data was stored outside the office.
Only 12% said they store data in the cloud, therefore if cloud computing is going to take off organisations need strategies that make the cloud more secure, said Watts.
The priority for most companies, he said, is to be able to tighten security to the point where they are comfortable to embrace the cloud and maximise its benefits.
According to Watts, an important first step will be improve authentication of end users so companies can be sure only authorised users are accessing applications and data.
