No enterprise can survive without adopting reasonable cybersecurity measures. Enterprises constantly face numerous cyber threats—even without realizing it. Some of the common threats are;
To encounter these threats, they need robust security practices. Some argue that the on-premises model offers greater security as it’s likely down the hall from security personnel and IT staff. In contrast, others claim that public clouds have more security as they adhere to strict security standards that former ones might or might not adhere to. Let’s end this struggle! This article will dive deep into Cloud vs on-premises security—which is better?
Cloud security is the collection of cybersecurity policies, technologies, best practices, and controls to address internal and external security threats to businesses. It’s imperative to consider cloud security as more enterprises are moving towards cloud computing from an on-premises model.
As IBM states, ‘Organizations need cloud security as they move toward their digital transformation strategy and incorporate cloud-based tools and services as part of their infrastructure.’
| Pros | Cons |
| Easily adaptable to changing business needs and highly scalable | The vulnerability of remote servers to cyber-attacks might raise concerns about sensitive information |
| More economical than on-premises solutions | Dependency on the internet |
| Remote workers can effortlessly access the resources whenever required, as long as there is an internet connection. | Organizations have diminished control over security infrastructure |
| The latest security features can be accessed through automatic updates | Misconfiguration chances, if not done appropriately |
| Cloud security minimizes the operational expenditure of data compliance | |
| Greater and centralized visibility into cloud resources |
On-premises security is considered as ‘in-house’ or ‘in your own environment’. Enterprises host the security infrastructure in their hardware.
| Pros | Cons |
| Customization of security solutions | Significant infrastructure investment |
| Complete control of security infrastructure | Maintenance and upgradation of security infrastructure might be complex and time-consuming |
| Offers predictable performance | Scalability might be challenging |
| Aspect | On-Premises Security | Cloud Security |
| Location and Hosting | Localized within the enterprise premise or another choosed location | Hosted offsite by cloud vendors |
| Control | Complete control over software, data, and hardware | Limited control |
| Cost Structure | High upfront capital investment and ongoing maintenance expenditures | Lower Initial Investment |
| Scalability | Limited by purchase capacity | Highly and easily scalable |
| Accessibility | Limited to VPN access or local network | Global access |
The debate on on-premises vs cloud computing revolves around the below-mentioned essential factors that highly influence operational efficiency and organizational strategy:
Security-as-a-service providers consider Multi-factor Authentication(MFA) and single sign-on(SSO) core to their service offerings. At the same time, on-premises vendors will see that as a value-added service to charge for.
Cloud-based security systems are built and designed to open standards that can simplify integration with other compatible systems and applications. On the other hand, on-premises security options, as designed with legacy technologies, might not possess a similar level of compatibility.
A secured internal data network must be installed to connect individual access and security control components to on-premises storage devices. The network must possess traffic prioritization capacity and speed to transit high-volume data. In the cloud security model, this transmission from individual devices happens via private or public internet connections.
Compliance management is a critical consideration in the on-premises vs cloud debate. An on-premises model yields direct control to validate compliance but can be expensive and time-consuming.
There is no straightforward justification for this question! The selection relies on multiple factors. Before selecting the one that best fits its enterprise, an enterprise must have pre-defined and well-clarified goals, needs, budget estimations, employees’ technical expertise, etc, on hand.
On-premises security might offer the advantage of being customized to particular requirements. However, this customization can be costly when maintaining and implementing security measures. On the other hand, cloud-based solutions minimize the complexity of security infrastructure maintenance. Considering the strengths and weaknesses of the on-premises and cloud security models, you must be ready to make a better-enlightened choice corresponding to your organization’s specific needs.
As we’ve explored, Both Cloud and on-premises have pros and cons from a security perspective. Which one you choose depends on your project requirements. If you want to understand better which suits your organization, you can select professional Cloud Migration Services. Their expert and certified cloud migration consultants might assist you in identifying the one that fits your enterprise—on-premises, cloud, or hybrid.
