Introduction
Today, cyber threats are becoming increasingly sophisticated, making data and system protection crucial for businesses of all sizes. Small and medium-sized businesses (SMBs) are particularly vulnerable to these threats because they often lack sufficient resources to build a robust cybersecurity system. Digital tools play a key role in protecting businesses from such challenges, and one of the most important technologies is Security Information and Event Management (SIEM).
SIEM (Security Information and Event Management) is a technology that combines Security Information Management (SIM) and Security Event Management (SEM). SIEM systems collect, analyze, and store event logs and data from various sources in real time, allowing for the detection of suspicious activity, threat analysis, and response.
Key Functions of SIEM:
Data Collection and Correlation: Gathering information from various systems, network devices, and applications. It collects information from different sources such as network devices, systems, and applications and correlates the data. This enables the detection of relationships between events from various components for quick identification of potential threats.
Anomaly Detection: Searching for unusual behaviors or events that may indicate threats.
Analysis and Reporting: Visualizing data and generating reports to meet security requirements.
Incident Alerts: Providing quick notifications about potential threats and abnormal activities for prompt response.
Wazuh, as an open-source platform, can be enhanced with XDR (Extended Detection and Response) to create a more powerful and integrated cybersecurity solution. The combination of Wazuh's SIEM and HIDS with XDR provides broader visibility into threats across all vectors — from endpoints to servers and networks. In this context, XDR helps unify threat data from various sources, facilitating the rapid detection of complex attacks. This integration also optimizes the incident response process, enabling security teams to respond, investigate, and neutralize threats more quickly through a single platform.
In summary, Wazuh is an innovative solution that combines the functionalities of SIEM, XDR, and additional tools for business protection. In this article, we will explore in detail why Wazuh is an important choice for small and medium businesses, provide an overview of the platform, analyze its cost-effectiveness, and consider its advantages and disadvantages.

For example, a financial company can use Wazuh to automate monitoring for GDPR compliance, thus avoiding the risk of fines.
Optimizing Security Costs Without Sacrificing Efficiency: Wazuh, as an open-source platform, provides powerful SIEM functionality without the high licensing costs. For companies with limited budgets, this is an important factor. For example, a medium-sized business that used commercial security monitoring solutions can switch to Wazuh and significantly reduce costs without sacrificing protection quality. In one case, a company reported a 30% reduction in cybersecurity costs due to using Wazuh.
Integrating Security into Existing IT Systems: Wazuh easily integrates with other cybersecurity solutions and infrastructure management tools such as AWS, Azure, or Google Cloud via API. If API integration with a particular service is not available, information can be obtained through syslog connections. This allows companies to create a centralized security monitoring system. For example, a retail company that uses several cloud services can integrate Wazuh for simultaneous monitoring of all platforms, receiving centralized alerts and reports on potential threats.
However, even with a powerful platform like Wazuh, it is important to have qualified specialists who continuously monitor security processes. Without professional supervision or a Security Operations Center (SOC) that specializes in real-time monitoring, analysis, and incident response, the system may not be as effective.
To clarify, a Security Operations Center (SOC) is a centralized unit responsible for monitoring, detecting, and responding to cyber threats in real time. SOC uses various technologies and methodologies to gather data on network activity, analyze security events, and respond to potential incidents. Integrating Wazuh into SOC processes can significantly improve the security team’s efficiency through automated threat detection, log collection, and compliance management.
