It is a common misconception that the applications and data hosted on a set of servers on-premise are more secure than on the cloud. For enterprises that already have an in-house IT team, on-premise security might prove optimal. However, most on-premise systems are not equipped to ensure the required level of security across the various layers—infrastructure, network, applications, and data.
The security measures you can take on-premise vs. what cloud providers can offer to keep your data and applications secure on the cloud may not be comparable considering the size of your security team, your budget for security, as well as your organization’s ability to implement automated risk monitoring systems 24X7. Cloud providers often dedicate greater resources and budget to ensure that their core systems are as secure as possible and regularly update these systems in response to potential security threats as it is their primary business. For an individual enterprise, it might be too expensive to allocate such efforts. For example, the comprehensive access control that Cloud providers (like AWS or Azure) offer is difficult to replicate on-premise given the tools, infrastructure investments, and large teams required. Therefore, rather than fearing whether the cloud is secure, it’s best to ask cloud providers what they offer in terms of security and compare their cloud security strategy to your own to make sure their strategy meets your requirements.
