Cloud computing has helped many firms manage data while saving on costs. A critical reason for businesses trusting cloud infrastructure by having data on the cloud is done by maintaining its security and integrity.
Here, encryption plays a major role in securing the data. This is applicable for cloud environments as well as on-premises. But which functions better?

Discover how approaches for internally hosted vs. cloud encryption mechanisms differ.
Understanding the distinctions can help companies make smarter decisions based on their needs.
Type of Architecture and Management
The infrastructure of both encryption mechanisms differs greatly.
With Self-Hosted Encryption
Encryption is entirely managed by the firm, and they have full control over the entire infrastructure. Deploying and maintaining security software and hardware is the responsibility of the firm.
Thus, with complete control, the firm must expend more resources to maintain solid security.
With Cloud Encryption
Most businesses are unable to deploy or maintain their own cloud infrastructure. So, they hire cloud service providers that also manage encryption. This secures data, both at rest and during transfers.
There is a Shared Responsibility Model when working with cloud vendors. This means that the firm is responsible for security in the cloud while the vendor manages security of the cloud.
Ease of Scalability and Flexibility
Business needs change with time and having a flexible and scalable environment makes it easier to manage the requirements.
With Self-Hosted Encryption
All infrastructure is managed by the firm itself. Thus, any need for scaling can become a complicated and costly procedure.
Excluding software and hardware costs, there are many manual updates which can create disruptions and potential disasters to business operations.
With Cloud Encryption
Cloud encryption has been designed in a manner where it is flexible and scaling the data is easier. Thus, vendors can easily accommodate large volumes of data.
Services work on a pay-as-you-go model so firms can scale according to needs and pay accordingly.
Managing Compliance with Regulations
Regulations around data security are constantly changing and ensuring compliance with them is key.
With Self-Hosted Encryption
The entire responsibility of meetings regulations is on the firm. The access and location make it easier for firms to comply with laws.
However, since it is all managed by the firm, they might require a dedicated team which adds to costs.
With Cloud Encryption
Cloud vendors manage compliance on their own with different regulatory requirements lightening the burden on firms.
However, there are challenges when the firm’s location is different from the service provider. So, firms might have to comply with local laws by themselves.
