The lack of industry-wide security standards is slowing business adoption of cloud services, according to cloud computing firm Mimecast.
Speaking at the V3 Security Summit, Mimecast chief scientist Nathaniel Borenstein said often businesses will not move to the cloud if they are unsure about which providers to trust when it comes to security.
He renewed previous calls he has made for industry standards that will allow businesses to properly evaluate cloud providers.
"All clouds are not created equally. The decision about who to trust is absolutely critical. There's a lack of evaluators telling you who to trust," said Borenstein.
Borenstein said independent evaluations are slowly becoming more common place due to the introduction of the ISO 27001, although many cloud vendors have yet to sign up to such best practice standards.
"What businesses are worried about is how to get the right cloud security. They can talk to other customers and exchange references but this is not entirely satisfactory," he added.
Borenstein made the point that cloud providers generally offer organisations a more secure model of computing than when IT departments try to secure their own infrastructure. However it is essential that the right cloud providers are trusted.
According to new Mimecast research, which surveyed over 700 IT professionals, 45 percent of businesses have concerns around the security of their data when it is stored in the cloud, while more than 70 percent believing an on-premise IT model is more secure than the cloud model.
Meanwhile, adding strength to Borenstein's argument, nine per cent of businesses said a lack of clear cloud security standards is holding them back from adopting the cloud.
