🔐 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
"Is SIEM really necessary for our organization?"
In July 2025, when it was revealed that the U.S. CISA failed to notify personnel in time despite confirming an external attacker's infiltration 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 the dots.
In April 2026, the SIEM Market Report published by Security News and Security World clearly answers this question.
In a survey of 1,100 security personnel in South Korea, 63.7% reported that they have already adopted or are operating SIEM, and organizations from small to large public institutions are rapidly considering the implementation of SIEM.
Let's explore 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 incidents involving telecommunications companies like SKT and KT to information leaks in fintech and medical institutions, attackers utilize multiple pathways in combination.
Such attacks cannot be detected by a single security solution.
This is why SIEM is gaining attention.
Collecting logs from dozens to hundreds of security devices to analyze correlations
Detecting anomalous behavior that appears normal in individual logs but is revealed when combined
Based on this, automated responses (SOAR) are 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 see the whole picture through a Single View becomes
the core competitive advantage in security.
📊 2026 SIEM Market Report: 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 reported they 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.
▲SIEM Solution User Survey [Source: Security News·Security World]
✅ 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 level is realistically considered by small and medium-sized enterprises, which is also why demand for cloud-based SaaS SIEM is increasing.
▲SIEM Solution User Survey [Source: Security News·Security World]
✅ The top solution integrated with SIEM = Network Security Devices (77.3%)
The integration rate of 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%), indicating that SIEM serves as a central hub for existing security investments rather than a standalone solution.
▲SIEM Solution User Survey [Source: Security News·Security World]
✅ The biggest concern is false positives — 32.7%
The most common challenge faced while 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 that a sophisticated AI-based analysis engine and automation system must also be in place.

💡 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.
This allows a small team to quickly handle vast amounts of security events.
③ Multi-Cloud and Hybrid Environment Response The ability to collect and analyze all logs on a single platform in environments where SaaS, on-premises, and cloud coexist becomes a key competitive advantage.
🚀 SecuLayer eyeCloudXOAR — Bringing These Three Together
SecuLayer's eyeCloudXOAR has been introduced in this SIEM special feature of 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 into a 5th generation security monitoring platform by adding AI capabilities to the existing 4th generation security monitoring platform.
1. What Does SecuLayer Define SIEM As?
SecuLayer defines SIEM not just as a log collection tool, but as "The Core of Autonomous SecOps."
Providing Intelligent Visibility: It goes beyond simply 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 digital transformation (DX) and AI transformation (AX) have eroded security boundaries, it has become difficult to block intelligent threats with a single device.
SecuLayer addresses customers' 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 equipped our system 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 very high satisfaction among actual users.
3. The Future of SIEM Desired by the Market
According to this feature article, customers now want 'accurate prioritization' and 'immediate response' rather than 'many detections.'
SecuLayer is keeping pace with these market needs by
Dramatically shortening 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.
Let's briefly review the key features.
For organizations struggling with false positive issues, 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 strategic partnerships with SK Shieldus, eyeCloudXOAR SIEM is already a proven 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.
