Why It's Time to Replace Legacy SIEMs

Back to Blog

Enterprises adopted SIEM (security information and event management) technology to make threat detection and response more efficient. However, while traditional SIEM solutions are well-suited to log management and compliance requirements, they weren’t optimized to keep up with the overwhelming volume of data in the present-day security operations center (SOC).

The typical security operations team received an average of 11,000 daily alerts, according to “The 2020 State Of Security Operations” report. Analysts are ignoring or turning off alerts because there’s too much noise and too many false-positives. At the worst, businesses have suffered a data breach or a cyberattack that should have been caught and stopped.

Legacy SIEMs are failing to deliver their expected value, leading to frustration for security teams and the need for a better approach.

Overcoming Common SIEM Limitations & Frustrations with SOC-as-a-Service

SOC-as-a-Service (SOCaaS), which combines a next-gen SIEM with a team of experts to provide 24/7 threat detection and response, is a compelling alternative for SOC teams. Here are six common SIEM frustrations and how emerging SOCaaS addresses them.

Frustration 1: Legacy Architecture 

Built on a cloud-native, next-generation SIEM platform, SOCaaS eliminates the disruptions and management complexities of traditional SIEM and enables rapid scaling and better resiliency.

Frustration 2: Limited Functionality

SOCaaS combines key capabilities, including SIEM, SOAR, UEBA, and a threat intelligence platform, into a single, unified SaaS offering to improve the speed and efficiency of the detection and investigation process.

Frustration 3: Unsupported Data Sources

Threat detection and response is only as good as the data you have. A SOCaaS provider with a vendor- and data source-agnostic model provides native support for critical data sources and telemetry. The vendor’s platform immediately ingests your data and improves the breadth, quality, and confidence of threat detection, reducing dwell time and enabling analysts to quickly detect and respond to hidden, evasive, and emerging threats.

Frustration 4: Weak Analytics

Legacy SIEMs weren’t optimized for the SOC and require extensive (expensive) configuration and tuning and rarely include a common information model (CIM) that would enable it to optimize analytics. SOCaaS providers rely on a next-generation SIEM platform purpose-built for the modern SOC. Threat detection and investigation combines data science and automation, a blend of threat detection methods, and contextual enrichment along with threat intelligence to dramatically reduce false positives and accelerate detection and response.

Frustration 5: Lack of Experts

SIEM is not sustainable if you can’t dedicate substantial staff resources to deploying, managing, and monitoring the platform. The strength of SOCaaS is not only the technology but also the expertise that comes with it. As a co-managed service, you can have as much control as you’d like without the expense of in-house staff to deploy, operate, and maintain the platform.

Frustration 6: Slow Time to Value

Legacy SIEM platforms often take a year or longer to fully configure and implement. SOCaaS takes very little to deploy, can be done quickly and remotely, and can be fully operational in as little as one month. 

These legacy SIEM frustrations led Cysiv to develop our own cloud-native, co-managed, multi-tenant SOC platform. Cysiv SOCaaS enables organizations of all sizes to achieve better value from their existing security investments while continuously improving cyber defenses.
