Cloud security vs On-premise security

What is Cloud Security?

Cloud security refers to protecting data, applications, and infrastructures involved in cloud computing. Cloud-based assets are secure due to various security measures, including data encryption, identity and access management, and network security. These measures guarantee the complete safety of the assets.

Cloud security is typically provided by the cloud service provider (CSP). It is often delivered as a service, meaning that the CSP handles security tasks such as updates, maintenance, and system monitoring. The CSP is responsible for safeguarding the underlying infrastructure and implementing security measures. While the user is responsible for ensuring their data and applications are on the cloud.

What is On-premise Security? 

On-premise or in-house security protects data, applications, and infrastructure hosted on an organization’s premises. It involves deploying security measures such as firewalls, intrusion detection systems, and encryption mechanisms to secure assets within the organization’s premises.

On-premise security is typically managed by the organization’s internal IT team, giving them complete control over the safety of their systems. It allows organizations to customize their security measures to meet their specific needs, and they can modify and adjust them as needed.


Our goal is to help your customers decide if cloud computing or on-premises technology will benefit them, and how to help them make this decision.


Its popularity makes it understandable that cloud computing is overgrowing. There is now more flexibility with cloud computing, but there are also some disadvantages compared to on-premise solutions. Meanwhile, on-premises security refers to the protection provided by physical measures at a business’s location. 


On-premise applications offer data security controls that cloud applications cannot typically provide.

Many procedures, technologies, policies, and controls are employed to secure data stored in the cloud. 


By utilizing a centralized approach, this solution facilitates compliance and establishes authentication procedures to protect sensitive data. 

 In cloud computing, APIs also present a risk since traditional security tools cannot fully understand them. 


Public clouds are similar to your on-premise environments in many ways, but one significant difference is that you must share security responsibilities with the cloud provider. 


Remind yourself that threats to your organization can occur anywhere and any level, depending on its structure. Therefore, you must implement adequate security measures if you use on-premise security. 


In most cases, on-premises security refers to the rules and tools used to safeguard the confidentiality, integrity, and performance of computer networks and their components, including hardware and software. 

By now, you probably have some idea about these two solutions. Here are some differences between them to help you understand better.


1. Implementation

IT infrastructure and resources are installed on-premises in an enterprise environment. The enterprise manages all related processes. 


The service provider hosts the resources, but enterprises have access to and can use them as they wish in cloud computing.


2. Cost


To deploy an on-premises server, you must purchase hardware, staff it for maintenance, and buy the software. Because of these reasons, companies choose cloud computing as a cost-saving measure. However, uncontrolled spending and cloud outages, which result in downtime, can incur additional costs. 


3. Uptime

Data centers are most concerned about their server uptime. It is common for on-premises systems to be up and running almost 100%. If these systems are adequately maintained, they can last for years. Most cloud services offer an SLA of more than 99%, which is substantially higher than anything typically found in an on-premises data center. You’d be better off with On-premise if you believe in your team.


 4. Customization


Cloud computing solutions are limited in customization capabilities, while on-premises solutions are infinitely customizable. For small businesses with simple requirements, cloud computing is the best option. In contrast, the level of customization available through on-prem can be invaluable for a large organization with complex IT requirements. 

5. Control



Enterprises with an on-premises solution have complete control over handling their data. As a result, companies with high privacy concerns tend to delay their entry into the cloud. Many companies and vendors have grappled with the issue of data ownership in a cloud computing environment.
