Understanding SIEM for Enhanced Endpoint Security

Introduction to SIEM and Endpoint Security

Securing endpoints is one of the most critical aspects of modern cybersecurity strategies. With the growing sophistication of cyber threats, businesses are increasingly turning to SIEM for endpoint security to ensure robust protection and threat visibility. But what exactly does SIEM bring to endpoint security? Let's dive into how SIEM endpoint security addresses the challenges organizations face today.

What is SIEM?

Security Information and Event Management (SIEM) is a comprehensive solution designed to monitor and analyze security events in real time. By collecting data from various sources, including servers, applications, and networks, SIEM creates a centralized view that offers deep insights into security threats. For organizations relying on SIEM for endpoint security, it means the ability to detect, prevent, and respond to malicious activities swiftly.

With endpoint SIEM, companies can correlate data from multiple endpoints, spotting anomalies and unauthorized access attempts. The result? Early detection of security breaches and minimized damage to critical assets.

Importance of Endpoint Security

Your endpoints are the gateways to your network. Whether it's laptops, smartphones, or other devices, each endpoint is a potential target for cybercriminals. Without robust endpoint SIEM solutions in place, these devices become vulnerable to malware, ransomware, and phishing attacks. SIEM endpoint security not only strengthens the security posture of these endpoints but also ensures continuous monitoring for suspicious activity.

Endpoint security powered by SIEM delivers several benefits:

• Enhanced visibility: SIEM tools provide a comprehensive view of all endpoint activities in real-time.
• Proactive threat detection: With SIEM for endpoint security, you can detect threats before they escalate.
• Automated response: SIEM systems can automatically trigger predefined responses to potential threats, reducing response times.

Challenges in Endpoint Security without SIEM

Relying on traditional endpoint protection without integrating SIEM endpoint security exposes organizations to significant challenges. Many businesses struggle with visibility across their networks, leaving endpoints exposed to attacks. Without SIEM, critical data might remain unnoticed until a breach has already occurred. Here's what companies face without SIEM for endpoint security:

• Lack of centralization: Managing endpoint security without SIEM results in scattered data and inefficiencies.
• Delayed threat detection: Without SIEM, recognizing anomalies across different endpoints becomes more challenging.
• Increased vulnerability: Manual monitoring of endpoints lacks the scalability to keep up with growing security threats.

Organizations that fail to integrate endpoint SIEM face a heightened risk of data breaches, costly downtime, and reputational damage.

In the fast-evolving world of cybersecurity, SIEM for endpoint security is no longer optional—it’s a necessity.

How SIEM Enhances Endpoint Security

As cybercriminals continue to develop more sophisticated attack methods, organizations are turning to SIEM for endpoint security to safeguard their networks. A robust SIEM endpoint security solution acts as a centralized hub for monitoring, detecting, and responding to potential threats across all endpoints. In a world where data breaches can cripple businesses, endpoint SIEM provides the comprehensive, real-time protection that modern enterprises need.

SIEM’s Role in Real-Time Monitoring and Threat Detection

Real-time monitoring is the backbone of SIEM for endpoint security. Unlike traditional security systems that often rely on scheduled scans or manual checks, SIEM continuously monitors every endpoint, gathering data such as login attempts, file access, software installations, and system performance metrics. This constant stream of data is analyzed in real time, allowing SIEM endpoint security to spot even the slightest deviations from the norm.

Technical details of real-time monitoring:

• Data aggregation: SIEM pulls log data from various sources—firewalls, intrusion detection systems (IDS), endpoint devices, and more—into a central platform.
• Normalization: The raw data from different systems are often in different formats. SIEM normalizes this data to create a unified dataset, enabling efficient analysis and cross-referencing.
• Correlation engine: SIEM's powerful correlation engine processes large volumes of data to detect patterns that indicate potential threats. For example, a spike in failed login attempts on an endpoint combined with unusual network traffic can trigger an alert, even if neither event alone is deemed suspicious.
• Machine learning (ML) and artificial intelligence (AI): Many modern SIEM solutions utilize ML and AI algorithms to enhance threat detection. These technologies allow SIEM endpoint security systems to "learn" normal behavior patterns and identify subtle changes that could indicate a breach, such as low-and-slow attacks or insider threats.

With these capabilities, SIEM for endpoint security can alert administrators to unauthorized access attempts, malware activity, or suspicious network traffic before they escalate into full-blown breaches.

Incident Response Capabilities of SIEM for Endpoint Security

Incident response is a critical feature of SIEM endpoint security, automating and expediting the process of mitigating detected threats. The integration of SIEM with Security Orchestration, Automation, and Response (SOAR) tools enhances the efficiency of incident response, offering faster containment and resolution.

Technical breakdown of SIEM-powered incident response:

• Automated actions: When a threat is detected, SIEM can be configured to automatically execute predefined playbooks. For example, if endpoint SIEM detects malware attempting to exfiltrate data, it can automatically isolate the compromised endpoint from the network, preventing the spread of the infection.
• Integration with SOAR: SIEM integrates with SOAR platforms to automate repetitive tasks such as log analysis, alert triage, and incident prioritization. SOAR tools can also automate workflows, assigning tasks to security analysts based on predefined rules.
• Threat intelligence integration: By connecting to external threat intelligence feeds, SIEM solutions enrich endpoint security data with real-time information on known threat actors, malicious IP addresses, and evolving attack techniques. This ensures that the system is aware of the latest threats and can block them preemptively.
• Forensic analysis: Post-incident, SIEM facilitates forensic investigations by providing a detailed timeline of the attack, including which endpoints were affected, how the threat spread, and what actions were taken. This data is crucial for improving future incident response efforts and closing any vulnerabilities that were exploited.

The combination of automated and manual response capabilities in SIEM for endpoint security ensures that threats are addressed quickly, minimizing downtime and preventing further damage.

The Importance of Centralized Logging for Endpoint Protection

Centralized logging is another key advantage of SIEM for endpoint security. Without SIEM, security teams must manually pull and analyze logs from each individual endpoint, which is time-consuming and error-prone. SIEM centralizes logs from all endpoints, enabling efficient analysis and correlation of data from a single interface.

Technical aspects of centralized logging in SIEM:

• Log aggregation: SIEM collects logs from all endpoint devices, servers, applications, and network devices. These logs include critical information such as system events, user activities, error messages, and security alerts. Having all this data in one place ensures that no event goes unnoticed.
• Log retention and compliance: SIEM solutions can be configured to retain logs for extended periods to meet regulatory requirements such as GDPR, HIPAA, and PCI DSS. This long-term retention is crucial for audit trails and forensic investigations, ensuring that security teams have the data they need when reviewing past incidents.
• Correlation across multiple data sources: SIEM does more than just store logs—it correlates data across multiple sources to detect complex, multi-vector attacks. For instance, SIEM can correlate suspicious user behavior on one endpoint with an unrelated security alert on another, identifying advanced persistent threats (APTs) that may go undetected by traditional security tools.
• Real-time and historical analysis: With centralized logging, SIEM systems can perform both real-time and historical analysis. Real-time analysis allows for immediate detection and response to threats, while historical analysis can uncover long-term trends and uncover previously undetected vulnerabilities.

By centralizing and correlating endpoint logs, SIEM endpoint security provides unparalleled visibility into the health and security of all connected devices.

SIEM for endpoint security is a cornerstone of modern cybersecurity. Its ability to provide real-time monitoring, automated incident response, and centralized logging makes it an indispensable tool for organizations aiming to protect their endpoints from evolving threats. Through SIEM endpoint security, businesses can effectively detect, analyze, and mitigate threats, ensuring comprehensive protection for their critical assets.

Key SIEM Features for Endpoint Protection

As the complexity of cyberattacks increases, organizations require more advanced tools to defend their endpoints—those vulnerable entry points in their network that attackers frequently target. SIEM for endpoint security offers a highly technical, integrated solution that not only monitors and protects, but also provides critical response capabilities. Below, we delve deeper into the technical features of SIEM endpoint security and how they strengthen an organization’s cybersecurity posture.

Correlation of Events Across Endpoints

One of the core technical advantages of SIEM for endpoint security is its ability to correlate events across multiple endpoints. Cyberattacks are rarely isolated; attackers often move laterally through networks, trying different endpoints until they find a vulnerable one. SIEM endpoint security continuously collects data from each endpoint and uses advanced algorithms to cross-reference and correlate events in real time, revealing patterns of behavior that may indicate a cyber threat.

Technical features of event correlation:

• Log aggregation: SIEM endpoint security systems gather logs from multiple sources such as endpoint devices, network appliances, firewalls, and intrusion detection/prevention systems (IDPS). These logs provide data about user activities, process executions, file access, system modifications, and network traffic across endpoints.
• Data normalization: SIEM converts data from different formats and structures into a standardized form. This allows the correlation engine to compare different logs in a meaningful way, such as comparing system events from a Linux server to application logs from a Windows-based workstation.
• Correlation rules: SIEM for endpoint security applies predefined or custom-built rules to correlate related events. For instance, a failed login attempt on one endpoint combined with a spike in outbound traffic from another could indicate a brute-force attack followed by data exfiltration.
• Machine learning (ML): Some SIEM solutions use ML models to identify more subtle correlations that may not be evident using standard rule-based detection. By analyzing historical data, the ML algorithms detect deviations from normal endpoint behavior, spotting advanced persistent threats (APTs) and other sophisticated attack methods that could otherwise remain hidden.
• Threat intelligence integration: SIEM integrates with external threat intelligence feeds to enhance event correlation. If an endpoint communicates with a known malicious IP address or downloads a file from a suspicious domain, the SIEM system immediately flags the activity as suspicious.

This event correlation capability provides a holistic view of the security landscape across endpoints, allowing organizations to detect coordinated attacks or anomalies that would be missed if only individual endpoints were monitored.

Automated Threat Response

The ability to respond to threats in real-time is a game-changer, and SIEM for endpoint security offers powerful automated threat response mechanisms. The technical backbone of SIEM's automated response capabilities includes integrations with other security tools, predefined workflows, and AI-driven decision-making processes that allow security teams to minimize manual intervention and prevent further damage swiftly.

Technical elements of automated threat response:

• Predefined response playbooks: Security teams can create playbooks within SIEM endpoint security systems that define specific actions to take when certain threats are detected. These playbooks can trigger responses such as isolating an endpoint from the network, terminating suspicious processes, or locking a user account.
• Real-time automation: SIEM’s automation engines operate in real time. For example, if a malware infection is detected on an endpoint, the SIEM system can automatically quarantine the device to prevent the malware from spreading to other parts of the network. This isolation can happen within seconds, much faster than human intervention.
• Integration with SOAR: SIEM endpoint security integrates with SOAR (Security Orchestration, Automation, and Response) tools, which add layers of automation and orchestration. SOAR platforms can coordinate actions across multiple security systems, such as firewalls, endpoint detection and response (EDR) tools, and anti-malware software. SOAR orchestrates complex multi-step processes, like blocking malicious IPs, generating security tickets, and notifying the relevant stakeholders, all in an automated fashion.
• Response optimization with AI: Advanced SIEM systems incorporate AI and ML to optimize threat responses. Based on historical data and patterns, the AI can dynamically adjust response actions. For example, it might decide to escalate an incident to human analysts based on the severity of the detected threat or adjust firewall rules to block incoming traffic from a suspicious region.
• Threat containment and remediation: Beyond detection, SIEM for endpoint security helps contain threats. For instance, if ransomware is detected, SIEM can trigger EDR tools to rollback affected files or block file-encryption attempts. This level of automation dramatically reduces the time attackers have to inflict damage.

With these automation capabilities, SIEM endpoint security ensures that threats are swiftly contained, often before human analysts even become aware of them.

Here’s how SIEM endpoint security improves threat detection:

• Correlated data from multiple sources: SIEM collects logs from every endpoint and security device across the network, creating a unified view of all activities. This correlation helps identify advanced threats that may span multiple endpoints, such as lateral movement attacks or coordinated phishing attempts.
• Advanced threat intelligence: Many SIEM for endpoint security solutions integrate with external threat intelligence feeds, giving them access to the latest data on known vulnerabilities, malicious IPs, and emerging attack techniques. This ensures that the system can detect even the most recent threats before they cause harm.
• Machine learning and behavioral analytics: SIEM endpoint security systems leverage machine learning to analyze typical user and system behavior. If any endpoint deviates from its established pattern—such as a user accessing sensitive files at odd hours or large amounts of data being transferred unexpectedly—SIEM will trigger an alert. This ensures threats like insider attacks or credential theft are quickly flagged.

By combining real-time data analysis, threat intelligence, and machine learning, SIEM for endpoint security provides a robust layer of protection that goes beyond traditional antivirus and firewall solutions.

Enhanced Visibility Across Endpoints

The more you can see, the better you can protect. One of the biggest advantages of SIEM endpoint security is the comprehensive visibility it provides across all endpoints. With endpoints such as laptops, mobile devices, and servers constantly connecting to corporate networks, having full visibility is crucial to maintaining control over the entire infrastructure.

Here’s how SIEM for endpoint security boosts visibility:

• Centralized monitoring: SIEM consolidates logs and events from all endpoints into a single dashboard, making it easy for security teams to track activity, investigate anomalies, and identify potential threats in real time. Without this centralized view, important clues may be missed, and attacks could go unnoticed.
• Endpoint health monitoring: SIEM endpoint security tracks the health and status of endpoints, ensuring that software is up-to-date, configurations are secure, and no unusual processes are running. This level of insight helps prevent endpoints from becoming weak links in the organization’s security posture.
• Granular reporting: SIEM solutions provide detailed reports on endpoint activity, making it easier to spot trends, vulnerabilities, or compliance issues. This reporting is not just valuable for security monitoring, but also for meeting regulatory requirements like HIPAA or PCI DSS.

With enhanced visibility, endpoint SIEM ensures that security teams can monitor every device in the network, detect threats, and maintain a strong, unified security approach.

Reduced Incident Response Times

In the event of a cyberattack, time is everything. Delayed responses can lead to significant data loss, system downtime, and reputational damage. SIEM for endpoint security plays a critical role in reducing incident response times by automating threat detection and providing actionable insights.

Here’s how SIEM endpoint security accelerates incident response:

• Real-time alerts: When SIEM endpoint security detects unusual behavior or a potential threat, it generates real-time alerts. These alerts are immediately sent to the security team, ensuring that action is taken without delay. Faster detection leads to faster containment, which significantly reduces the impact of an attack.
• Automated responses: SIEM systems can be configured to automatically respond to certain threats without waiting for human intervention. For example, if SIEM for endpoint security identifies malware on an endpoint, it can quarantine the device, block malicious IP addresses, or shut down suspicious processes. Automation ensures threats are neutralized before they spread.
• Streamlined workflows: SIEM integrates with incident response tools and workflows, making it easier for security teams to follow a structured, efficient response process. SIEM’s centralized data also provides context for each incident, helping teams understand the scope of the attack and determine the best course of action quickly.

Integrating SIEM with Endpoint Devices

For businesses to maintain a strong security posture, the integration of SIEM for endpoint security must be done with careful attention to technical details. This ensures the seamless monitoring, detection, and response to security incidents across all devices. A well-executed integration not only protects individual devices but also strengthens the overall security of the organization. Let’s dive deeper into the technical aspects of SIEM endpoint security, including best practices for integration, security protocols, and policy management.

Best Practices for SIEM and Endpoint Integration

Integration of SIEM with endpoint devices involves several key technical steps that ensure the SIEM system captures and analyzes data from all endpoints effectively. Each endpoint is a potential entry point for attackers, so comprehensive integration is essential.

Key technical best practices include:

• Endpoint agent installation and configuration: Deploying SIEM agents on endpoint devices is crucial for data collection. These agents capture logs and event data such as user activity, file modifications, and system alerts. Depending on the SIEM platform, agents may also offer advanced features like process monitoring, disk encryption status, and network traffic analysis. Agents should be configured to forward this data to the SIEM system in real time, ensuring no delays in threat detection.
• Log collection and normalization: One of the technical challenges of SIEM for endpoint security is the ability to collect and normalize logs from different types of endpoints. Logs from Windows, Linux, and macOS devices, as well as IoT or mobile devices, can be formatted differently. SIEM systems use normalization techniques to convert these logs into a common format, allowing the correlation engine to analyze them uniformly. This process often involves the use of parsing scripts or log collectors to extract relevant data fields like IP addresses, user IDs, and event timestamps.
• Data encryption: Logs collected from endpoints can contain sensitive information such as user credentials, IP addresses, and system configurations. It is critical to ensure that all data transmitted from endpoints to the SIEM system is encrypted using protocols like TLS or SSL. This prevents attackers from intercepting or manipulating log data in transit, ensuring the integrity of the security information.
• Performance optimization: SIEM systems can generate a large volume of logs, especially in environments with thousands of endpoints. To prevent performance bottlenecks, organizations should optimize log forwarding by configuring event filtering on the endpoint agents. For example, filtering out low-priority events or reducing the logging verbosity on non-critical endpoints can help manage the load on the SIEM system. In addition, load balancing techniques can be used to distribute log collection across multiple SIEM servers.

Following these best practices ensures that SIEM endpoint security is implemented with a focus on scalability, reliability, and comprehensive data collection.

Security Protocols for Endpoint Device Monitoring

Implementing proper security protocols is essential to ensure that SIEM endpoint security can effectively monitor and protect all connected devices. These protocols govern how data is transmitted, how endpoints are authenticated, and how logs are handled securely.

Technical security protocols include:

• Syslog and Security Event Forwarding (CEF/LEEF): For efficient log forwarding from endpoints to the SIEM system, standardized protocols like Syslog, Common Event Format (CEF), and Log Event Extended Format (LEEF) are widely used. These protocols define how log data is structured and transmitted between systems, enabling consistent and reliable log collection. In addition, using these standards ensures that the SIEM system can integrate logs from third-party devices, such as firewalls and network appliances.
• Endpoint encryption and security: Data encryption, both at rest and in transit, is a critical component of SIEM endpoint security. Using AES-256 encryption for stored logs and ensuring data is transmitted over secure TLS connections prevents attackers from accessing sensitive endpoint information. Additionally, full-disk encryption on endpoints ensures that if a device is compromised, the data remains protected.
• Authentication and authorization protocols: Authentication protocols like Kerberos and OAuth, combined with Multi-Factor Authentication (MFA), provide strong user verification methods for accessing endpoint devices. SIEM for endpoint security tracks and logs every authentication attempt, alerting administrators if unusual login behavior is detected. For example, repeated login attempts from different locations or at unusual times may indicate a brute force or credential stuffing attack.
• Endpoint telemetry: Modern SIEM systems use endpoint telemetry data to monitor key metrics related to device performance and security status. This data includes CPU usage, memory consumption, running processes, open network connections, and device configurations. Integrating endpoint telemetry into SIEM for endpoint security enables real-time monitoring of system health and identifies anomalies that may indicate a security breach or malware infection.

By implementing these protocols, endpoint SIEM systems can efficiently gather, process, and secure data from all endpoints, ensuring that security teams have the visibility they need to detect and respond to threats.

SIEM and Endpoint Security Policy Management

One of the primary advantages of SIEM for endpoint security is its ability to enforce security policies across diverse devices, ensuring that every endpoint complies with organizational standards. Managing these policies through the SIEM system ensures consistency and reduces the risk of human error.

Key technical aspects of policy management include:

• Group Policy Objects (GPO) and Endpoint Security Policies: For Windows environments, integrating Group Policy Objects (GPO) with SIEM allows for centralized management of security policies. For example, policies related to password complexity, user privileges, firewall configurations, and software updates can be pushed to all connected endpoints. SIEM endpoint security systems then monitor compliance with these policies, generating alerts when a device falls out of compliance.
• Endpoint Configuration Management: SIEM for endpoint security integrates with configuration management tools like Ansible, Puppet, or SCCM (System Center Configuration Manager) to automate policy deployment across endpoints. These tools ensure that all devices adhere to the same security configurations, reducing the risk of vulnerabilities due to misconfigurations. For example, endpoints that have not applied critical security patches can be flagged by the SIEM, and remediation workflows can be initiated.
• Continuous compliance monitoring: SIEM systems continuously monitor endpoint compliance with internal policies and external regulatory requirements. For instance, PCI DSS or HIPAA compliance requires that specific security measures be enforced on all devices. SIEM for endpoint security can generate compliance reports that highlight non-compliant devices, ensuring that organizations stay within regulatory boundaries.
• Automated incident response for policy violations: When SIEM endpoint security detects a policy violation, such as an unpatched vulnerability or unauthorized software installation, it can trigger automated remediation actions. These might include quarantining the device, revoking user access, or initiating a patch deployment process. This automation ensures that security gaps are closed quickly, reducing the window of opportunity for attackers.

By centralizing policy management, SIEM for endpoint security ensures that organizations maintain a consistent and secure environment across all endpoints, helping prevent breaches and reducing the risk of compliance violations.

Integrating SIEM with endpoint devices requires a blend of best practices, robust security protocols, and effective policy management. By implementing these technical measures, organizations can ensure that SIEM for endpoint security operates effectively, providing comprehensive visibility, advanced threat detection, and automated incident response capabilities that protect all endpoint devices from cyber threats.

SIEM vs Other Endpoint Security Solutions

As organizations face increasingly complex cybersecurity threats, choosing the right tools to protect their endpoints is critical. While SIEM for endpoint security is an essential component of a comprehensive defense strategy, it is important to understand how it compares to other solutions like Endpoint Detection and Response (EDR) and antivirus software. Knowing when to use SIEM endpoint security over other tools can be the difference between a minor incident and a devastating breach.

Comparing SIEM with Endpoint Detection and Response (EDR)

At first glance, SIEM for endpoint security and EDR may seem like similar tools, both designed to protect endpoints and detect malicious activities. However, they serve different roles within the cybersecurity ecosystem. Understanding their key distinctions helps organizations make informed decisions on when to deploy each solution.

SIEM endpoint security focuses on:

• Log aggregation and correlation: SIEM systems collect, aggregate, and analyze logs from various sources, including endpoints, servers, firewalls, and network devices. SIEM’s strength lies in its ability to correlate data from multiple systems to detect complex attack patterns that might span several devices. For example, SIEM can identify connections between suspicious network traffic and unauthorized file access on multiple endpoints.
• Comprehensive visibility: SIEM provides a holistic view of the entire network, offering insights into all endpoints and their interactions with other devices. This allows for a more macro-level analysis of security incidents and helps identify larger attack campaigns that target multiple endpoints simultaneously.
• Compliance and reporting: SIEM is particularly useful for organizations that must adhere to strict compliance requirements, such as PCI DSS, HIPAA, or GDPR. It automatically generates detailed audit trails and compliance reports by logging security events across endpoints, helping businesses stay compliant.

EDR, on the other hand:

• Real-time endpoint monitoring: EDR is laser-focused on monitoring the behavior of individual endpoints in real time. It tracks and analyzes processes, applications, and file activity on the endpoint itself, allowing for rapid detection of threats like malware, ransomware, or fileless attacks.
• Automated response and remediation: EDR solutions can automatically isolate compromised endpoints, kill malicious processes, or roll back changes made by malware. While SIEM endpoint security typically correlates data from multiple systems, EDR is more focused on providing immediate, automated responses to endpoint-specific threats.
• Detailed forensics: EDR excels at providing in-depth forensic data for incident investigations. Security teams can use EDR to trace the exact path an attacker took on a specific device, helping them understand how the attack occurred and how to prevent it in the future.

Many organizations find that using both solutions together provides the best coverage.

Differences Between SIEM and Antivirus Software

While antivirus software has been a staple of endpoint protection for decades, its capabilities are far more limited compared to SIEM for endpoint security. Modern cyberattacks are increasingly sophisticated, often bypassing traditional antivirus defenses. Endpoint SIEM provides a broader and more proactive defense strategy.

SIEM endpoint security offers:

• Threat intelligence and correlation: SIEM systems leverage global threat intelligence feeds to stay updated on the latest malware, vulnerabilities, and attack vectors. By correlating these external data points with internal endpoint activity, SIEM for endpoint security identifies more subtle or advanced threats that antivirus software might miss.
• Multi-layered detection: Unlike antivirus software, which primarily relies on signature-based detection to find known threats, SIEM uses a combination of signature, anomaly, and behavior-based detection techniques. This makes endpoint SIEM more effective at catching zero-day threats, polymorphic malware, and fileless attacks that evade traditional antivirus solutions.
• Enterprise-wide visibility: SIEM aggregates logs and events from multiple endpoints and other network devices, providing a full picture of the organization’s security landscape. Antivirus software, on the other hand, typically operates at the device level and is limited in its ability to detect threats that involve multiple endpoints or network components.

Antivirus software:

• Signature-based protection: Antivirus software scans endpoints for known malware signatures, making it effective for catching well-documented threats like trojans, viruses, and worms. However, this signature-based approach means it struggles to detect new or evolving threats.
• Limited scope: Antivirus tools are generally designed to protect individual devices and don’t provide the same level of centralized monitoring or enterprise-wide insight that SIEM for endpoint security offers.

In today’s threat landscape, antivirus software alone is insufficient. While it plays a role in defending against basic malware, SIEM for endpoint security delivers the comprehensive, advanced threat detection required to protect against modern attacks.
