Security concerns are preventing wider adoption, despite industries increasingly adopting the public cloud, according to a new report from Barracuda Networks.

Survey respondents said they currently run 44% of their infrastructure in the public cloud, but expect this percentage to double in the next five years.

According to 74% of IT leaders, security concerns restrict their organisations migration to the public cloud.

They survey also found that 77% of IT decision makers said they believe that public cloud provider are responsible for securing customer data in the cloud, and 68% said they believe these providers are responsible for security customer applications.

Despite the lack of clarity, 30% of organisations reported they have not added additional security layers to cloud deployments.

Tim Jefferson, vice president of public cloud at Barracuda, said: “This survey confirms what we are hearing from customers and partners; security still remains a key concern for organizations evaluating public cloud, and there’s confusion over where their part of the shared responsibility model begins and ends.

“Many organisations realise their cloud deployments can be inherently more secure than an on-premises deployment because cloud providers are collectively investing more into security controls than they could on their own.”
