Debunking
three common security myths of private cloud
Jake Madders, co-founder and director of Hyve Managed Hosting explains the benefits of the private cloud.
A
t the end of 2021 more than two-thirds of all enterprise infrastructure was cloud-based. What’s more, 81% of business leaders reported that they had a multi-cloud strategy in place or in
the works. Many of these opt to use the private cloud for more sensitive workloads rather than solely relying on the public cloud. This is because a private cloud can be tailored to the goals and needs of a single organisation, as opposed to the off-the-shelf public cloud which is used by many different organisations on a pay-as-you-go basis. One of the main benefits of the private cloud is that only the organisation
has access to their data, as it is encrypted and much more secure. This means more control, security and greater performance, along with the ability to comply with local business and government regulation. When considering the security advantages of the private cloud, it’s
important to remember that there are three different types of private clouds, each with different capabilities: • There is the virtual private cloud, a confined environment which is located within a public cloud – although the server is shared, the virtual logic ensures everything remains private.
• The second is the hosted private cloud, where servers are not shared – instead, the provider configures the network and it is owned by a single organisation.
• The third is the managed private cloud – where the provider manages all aspects of the cloud for an organisation.
Despite the security advantages of private cloud being common knowledge in the technology industry, there are still some myths lingering – in particular around its security capabilities – and it’s time these myths were debunked.

Myth 1: The private cloud is more prone to cyber-attacks than on-premise storage The myth that the private cloud is more vulnerable to attacks than on-premise sites stems from the popular and misinformed idea that non-physical servers are less secure, but the reality is that cyberattacks and breaches can happen regardless of setup. The public cloud could certainly expose you to more potential cyber-attacks
as it is shared and security measures could be diminished. However, a well- designed cloud security strategy vastly reduces the risk of cyber-attacks, so that even with these risks, cloud computing is often more secure than on-premise computing. Organisations need to have the right detection and response solutions in place to respond to potential vulnerabilities and breaches. A private cloud though, can boost security. For example, it can enable
remote workers to use technology such as virtual machines to make sure that employees fall under company protection, regardless of where they log in from. This is unlike an on-premise solution which is less agile and more vulnerable when employees log in remotely. It’s also misconceived that data is less secure when stored on the cloud
because more exposure means more risk, while on-premise infrastructure is safer as it’s situated physically closer to the end-user. This is not the case and in fact, on-premise storage is usually more vulnerable because it’s more expensive. Maintaining even moderate – usually insufficient – security with an on-premise storage is costly because you must employ staff to continuously monitor data and ensure servers are constantly patched and updated in real time. When you use a private cloud provider on the other hand, all security patches and updates are maintained externally at a lower cost.
