The Key Differences Between On-Premises and Cloud Cybersecurity Solutions

The importance of data security cannot be questioned in today’s business environment as organizations strive to enhance their cybersecurity. A business must consider many factors while enhancing its storage backups, security, enterprise resource planning (ERP), and software.

Also, businesses have to decide if cloud infrastructure or on-premises data solutions are the proper fit for their IT services. A managed service provider (MSP) or a client has a crucial job to make the right choice when deciding to invest in data services. Here are the key differences between on-premises and cloud cybersecurity solutions.


This is the most important aspect of cybersecurity solutions and business is at the forefront to opt for the right infrastructure that guarantees data safety and ensures it is apt with current data security trends and practices. Large organizations in the private sector and government have sensitive data to protect hence the need to make the proper choice when investing in a data solution.

For companies offering banking services and on-premise data, the solution makes more sense because of the nature of engagement to clients that need absolute privacy that third-party cloud computing services may not provide.

When choosing a security solution, next-gen email security software comes in handy to prevent malware, phishing, attacks, and other security concerns on the cloud. There have been many reports of attacks on cloud computing deployment hence the need to enhance it with a better email security solution.


Another factor an organization should consider when differentiating between on-premise and cloud computing solutions is scalability. Cloud computing has a clear competitive edge in this regard because the data hosts prioritize customer needs and would most like to modify their resources to meet client needs. An example, when a company needs to enhance its services to a larger market, in this case, the host will easily alter the service to match the customer’s expectations.

With regards to on-premise, the whole factor is ownership of the data resources, and this may change from time to time depending on the organization’s needs. The business environment keeps evolving, clients’ expectations and services also change, and in this case, the organization has to invest in data solutions that fit these expectations.


The cost implication is important for many organizations in a competitive business environment and saving on IT service costs is significant. When it comes to costs, in cloud-based computing, an organization doesn’t incur the cost of installing any software as the services are from a third-party cost. The only cost will be a monthly fee to the host to continue providing the solutions, and most of the time, the fee is minimal.

For an on-premise solution, the organization will have to incur the initial costs of installing the hardware, buying software licenses, paying staff to maintain the servers, and other operating expenses. There will be no monthly fee because the servers are owned by the organization, which may be an advantage. Still, when you calculate the cost of investments and operation costs, cloud computing solutions have the upper hand.


Time is of the essence in business, and most organizations would want maximum uptime to enhance their services. Challenges with systems can have negative implications in running an organization, especially when clients need instant and 100% secure service.

Transaction details, the e-signatures, and overall customer data, order status, etc., should be available to customers at all times.

Cloud computing relies on external servers, and when the internet is off, you end up losing significant data. On the other hand, on-premises have internal savers and most of the time may not require the internet to store data.

But servers may also fail for on-premise solutions, which can greatly affect the operations and can be costly too. Cloud computing has a better server advantage because many external servers can guarantee better uptime, especially if there is more than one server.

When one server gets affected or stops working, other servers will still be at service, and this gives cloud computing a competitive edge over the on-premise solution. But if the on-prem has no server problems, it remains a better option.

Time to implement

On one end, cloud-based solutions are pretty straightforward on uptime because you simply sign into a host and make an order, and import data from other institutions within a short time. On the other hand, on-premise solutions can be challenging, especially when customized because they take much time to implement.

An on-premise solution has to be physically brought to the organization’s place of business, installed, plus you will have to manually import data from other organizations via datasheets. This can take a long time before being available for use compared to cloud computing which takes a win when it comes to timely implementation.


This is also a key factor a business should consider before deciding which option to go for. While cloud solutions don’t offer many options, small to medium-sized organizations without the need for complex IT services can opt for cloud computing. On the other hand, on-premises are perfectly customized and are the better option for large organizations with complex IT solution needs.

On-premise customization can make a huge difference for a large organization because of the customization feature. With this said, on-premise wins on customization because cloud computing is more rigid. However, custom configurations will come at an extra cost for the on-premise solutions.

On-premises vs. cloud deployment

The key difference here is that an on-premise deployment maintains its solutions in-house, while a third party hosts the services in a cloud environment. A business has a key responsibility of keeping a solution with all its features. On-premise is great with businesses that already have an in-house IT team ready to run the infrastructure.

With a dedicated internal IT department, you will be able to deploy your security software in-house. On the other hand, cloud computing allows organizations to get security solutions from the service provider. It can be a public cloud, a private cloud, or a hybrid of both.
