🔐 Security World SIEM Special Feature, Reinterpreted from SecuLayer's Perspective!

Hello, we are SecuLayer, a company specializing in AI-based cybersecurity solutions.

​

📌 The Most Common Question Security Personnel Are Facing These Days

"Does our organization really need SIEM?"

In July 2025, when it was revealed that the U.S. CISA failed to notify personnel in time despite confirming an external attacker's intrusion into internal systems, the security industry was taken aback. This was not just a simple mistake.
It happened because they collected logs but failed to connect them.

In April 2026, the SIEM Market Report published by Security News and Security World answers this question very clearly.

In a survey of 1,100 domestic security personnel, 63.7% reported that they have already adopted or are operating SIEM, and organizations from small businesses to large public institutions are rapidly considering the implementation of SIEM.

Let’s take a look at the key trends of the 2026 SIEM market from SecuLayer's perspective.

🔍 Why SIEM Now — Changes in the Threat Environment

​

Recent security threats do not occur in isolation within a single system.

From breaches at telecom companies like SKT and KT to information leaks in fintech and healthcare institutions, attackers utilize multiple pathways in a complex manner.
Such attacks cannot be captured by a single security solution.

This is why SIEM is gaining attention.

​

• Collecting logs from dozens to hundreds of security devices in one place to analyze correlations

• Detecting anomalous behaviors that appear normal in individual logs but are revealed when combined

• Based on this, automated responses (SOAR) can be connected to immediately block threats

​
As the IT environment becomes more complex due to digital transformation (DX), AI transformation (AX), and the spread of BYOD, the ability to view everything from a single view becomes a core competitive advantage in security.

📊 2026 SIEM Market Report: The Reality in Numbers

​

This Security News report clearly shows the true face of the domestic SIEM market.

​

✅ More than 50% of organizations have already adopted or plan to adopt SIEM

39.1% of respondents are currently operating SIEM, and 10.9% plan to adopt it within a year.
Including the 38.2% who feel the need but have no plans yet, it indicates that most organizations recognize the necessity of SIEM.

​

✅ The most common annual budget is between 10 million to 30 million KRW

Regarding implementation costs, 33.7% of respondents expect it to be below 10 million to 30 million KRW.
This is a level that small and medium-sized enterprises can realistically consider, which is also why demand for cloud-based SaaS SIEM is increasing.

​

✅ The top solution integrated with SIEM = Network Security Devices (77.3%)​

The proportion of integrating logs from network security devices such as firewalls, IPS, IDS, and VPNs into SIEM was overwhelmingly high. Following this were EDR and XDR (39.1%), and server and virtualization (38.2%), which indicates that SIEM serves as a central hub for existing security investments rather than a standalone solution.

​

​

✅ The biggest concern is false positives — 32.7%

​

The most common response regarding the challenges of operating SIEM was 'too many false positives.'
Following this were log management and costs (30%), and lack of analytical personnel (25.5%).
This shows that SIEM is not just about implementation, but requires a sophisticated AI-based analysis engine and automation system to be effective.

💡 SIEM is No Longer Just a 'Log Repository'

​

As of 2026, SIEM is evolving in three major directions.

① AI-based Anomaly Detection (UEBA) Rule-based detection only captures known patterns.
Now, through User and Entity Behavior Analysis (UEBA), AI can learn and detect new threats without predefined rules.

② SOAR Integration Automation Automates the entire process from detection to analysis to response based on playbooks.
Even with a small workforce, it allows for rapid processing of vast security events.

③ Multi-Cloud and Hybrid Environment Adaptation The ability to collect and analyze all logs on a single platform in environments where SaaS, on-premises, and cloud are mixed becomes a key competitive advantage.

🚀 SecuLayer eyeCloudXOAR — Bringing These Three Together

​

SecuLayer's eyeCloudXOAR has been introduced in this SIEM special feature by Security World.

eyeCloudXOAR SIEM​ is a leading domestic SIEM solution that integrates SIEM, SOAR, and UEBA into a single platform according to business processes. As the name 'XOAR (eXtended SOAR)' suggests, it has evolved from the existing 4th generation security monitoring platform by adding AI capabilities to become a 5th generation security monitoring platform.

1. What does SecuLayer define as SIEM?​

SecuLayer defines SIEM not merely as a log collection tool, but as "The Core of Autonomous SecOps."

• Providing Intelligent Visibility: It goes beyond merely collecting data and acts as the 'brain' of security operations.

• Starting Point for Autonomous Response: It becomes the core foundation of an autonomous security system capable of responding to advanced threats on its own.

​​

2. Why Choose eyeCloudXOAR SIEM Now?

​

As the security perimeter has collapsed due to digital transformation (DX) and AI transformation (AX), it has become difficult to block intelligent threats with a single device.
SecuLayer addresses customer concerns through the following core values.

• Maximizing Analytical Efficiency: We focused on enhancing actual analytical efficiency, moving beyond the past notion of SIEM as merely a 'log storage' tool.

• AI-based Sophisticated Detection: We have equipped our solution with AI detection capabilities that reduce alert fatigue for monitoring personnel.

• Intuitive Operating Environment: We provide a user-friendly dashboard that allows users to grasp threat situations at a glance without complex queries, resulting in high satisfaction among actual users.

​

3. The Future of SIEM Desired by the Market

​

According to this feature article, customers now prefer 'accurate prioritization' and 'immediate response' over 'many detections.'

SecuLayer is aligning with these market needs by​

• Dramatically reducing the time from detection to response through organic integration with SOAR,

• Providing integrated visibility that encompasses both on-premises and cloud environments to achieve seamless security in any setting.

​

Let’s briefly look at the key features.

​

For organizations struggling with false positives, AI-based precise detection reduces alarm fatigue, and for SOCs facing personnel shortages, automated playbooks maximize operational efficiency.

​

With a 4-year consecutive market share leader in the procurement market (2021-2024), a projected market share of 59% in 2024, and service enhancement through a strategic partnership with SK Shieldus, eyeCloudXOAR SIEM​ is already a validated platform in the domestic security landscape.

​

In Conclusion — It's Not Too Late to Start SIEM Now

​

SecuLayer will continue to lead the way in making corporate security operations smarter and more autonomous through eyeCloudXOAR SIEM.
