Getting Started with Cloud SIEM: What You Need to Know

Keeping a company’s digital systems secure meant setting up servers in a locked room, managing mountains of log data, and relying on IT teams to manually sift through alerts. It worked — for a while. But as businesses moved to the cloud, things got a lot more complex. Enter SIEM: Security Information and Event Management.

The shift from legacy models to cloud-native approaches has led to a growing interest in the comparison between Traditional SIEM vs Cloud SIEM.

In this blog, we’ll take you through that journey — from the early days of SIEM to the rise of cloud-based solutions — and show how Regami is helping businesses stay one step ahead with smarter, more adaptive cloud security.

Stay ahead of evolving cyber threats with AI-powered Cloud SIEM. Explore how Regami’s Cloud Engineering experts can help you build smarter, scalable security from the ground up.

What Is SIEM and How Has It Evolved?

Security Information Management (SIM) and Security Event Management (SEM). The result was security information and event management (SIEM). SIEM systems could detect prospective security threats by centralizing, normalizing and processing event data throughout an IT environment. This helped security teams become more efficient and effective as they addressed ever-growing amounts of traffic throughout complicated IT infrastructures. But despite their benefits, the SIEM systems had its drawbacks as well.

Cloud SIEM technologies are built with the modern-day IT environments heavily depending on such services as AWS, Azure, and Google Cloud, while traditional SIEM products tend to be located on premises and managed on-site.

Traditional SIEM vs Cloud SIEM: Key Differences and Advantages

1. Deployment Model

The majority of traditional SIEM deployments take place on-site, requiring significant hardware expenditures and upkeep. Typically, they require expert personnel to set up and run.

Since cloud infrastructure is the foundation of cloud SIEMs, quick deployment is possible without requiring a complex hardware configuration. Additionally, this cloud-based strategy relieves IT workers of a significant portion of the operating burden, including patch management and hardware replacement.

2. Data Sources

Traditional SIEMs need extensive reconfiguration to support cloud-based data sources, and they typically gather information from on-premises environments. Integrating new data sources can be slow at times, and establishing a common security environment can be challenging

Cloud SIEMs offer support for a large number of on-premises and cloud data sources. They are now able to see all their IT assets and have the confidence that all the data streams critical to them are being watched. With their advanced data correlation and normalization capabilities, cloud SIEMs can support a variety of data formats from a large number of sources.

3. Scalability

Scaling is usually limited in the case of conventional SIEMs. Buying and deploying more hardware is usually necessary in order to scale an on-premises SIEM, which can be expensive and time-consuming. This can lead to security coverage gaps due to the lag in response to new threats and IT changes.

Since cloud infrastructure is inherently elastic, cloud SIEMs can be easily scaled to address evolving security requirements and increasing volumes of data. Cloud SIEMs can scale security monitoring across more business units or ingest more data during spikes without demanding heavy hardware investment or reconfiguring.

4. Accessibility and Management

The on-premises access requirements of traditional SIEMs might restrict the flexibility of security operations. Traditional SIEM management is additionally more time-consuming and resource-intensive, frequently requiring expert personnel for troubleshooting and maintenance.

Compared to on-premises SIEMs, cloud SIEMs provide superior management capabilities and accessibility. Security teams have real-time visibility and control regardless of their location because they can often be accessible from any location with an Internet connection. This is especially advantageous for firms implementing remote work models or distributed teams.

5. Maintenance and Updates

Traditional SIEMs need constant manual upkeep and updating, which is time-consuming and prone to human mistakes. Maintaining the system updated and safe entails periodic patches, software updates, and hardware checks, all of which add to increased cost of operation and resource utilization.

Cloud SIEMs are backed by cloud service providers, who take care of the underlying hardware and software updates, ensuring that the SIEM system always runs the latest versions with the latest security patches. This takes away the burden from the organization to spend resources on these efforts, allowing staff to concentrate on more important security activities.

6. Cost Structure

Traditional SIEMs usually come with high initial expenses for hardware, software licenses, and installation. Maintenance, updates, and hardware replacement costs can mount over time, and the overall cost of ownership could be higher.

Cloud SIEMs follow a subscription model, where the organization pays for the usage, thus enabling enhanced budget planning and forecasting. This does away with the initial capital outlays involved with purchasing and rolling out on-premises hardware and software, providing lower barrier to entry financially.
