<p>Modern network environments demand a cohesive and <a href=”https://www.techtarget.com/searchsecurity/The-ultimate-guide-to-cybersecurity-planning-for-businesses”>comprehensive security posture</a> as attack surfaces expand and hybrid environments become more complex.</p>
<p>Endpoint detection and response, security information and event management and security orchestration, automation and response are three essential tools that help ensure enterprise resilience. Let’s discuss EDR, SIEM and SOAR, examining the strategic importance of integrating the three security tools, as well as looking at common use cases, implementation, maintenance routines and challenges.</p>

<p>Before delving into the strategic value and real-world use cases of these three technologies, it’s worth reviewing what they do.</p>
<h3>EDR</h3>
<p><a href=”https://www.techtarget.com/searchsecurity/definition/endpoint-detection-and-response-EDR”>EDR</a> tools focus on endpoint devices, including servers, workstations, laptops and similar components. Their goal is to detect, investigate and remediate malicious activity. EDR tools <a href=”https://www.techtarget.com/searchsecurity/feature/How-EDR-systems-detect-malicious-activity”>use agents</a> to watch processes, isolate hosts, quarantine files and take other actions as needed.</p>
<h3>SIEM</h3>
<p><a href=”https://www.techtarget.com/searchsecurity/definition/security-information-and-event-management-SIEM”>SIEM</a> systems ingest and correlate log files and events from endpoints, network devices, applications, identity providers and other components. They work with cloud and on-premises resources to centralize alerting, archiving and analytics for security data, aiding investigations, threat hunting and demonstrating compliance.</p>
<h3>SOAR</h3>
<p><a href=”https://www.techtarget.com/searchsecurity/definition/SOAR”>SOAR</a> tools tie everything — SIEM, EDR, ticketing, etc. — together to automate incident response workflows using playbooks. This reduces manual efforts, speeds responses, establishes containment and implements remediation.</p>
<p>Playbook functionality might include blocking IPs, disabling accounts, opening tickets and enriching alerts and indicators of compromise.</p>

<h2 class=”section-title”><i class=”icon” data-icon=”1″></i>The strategic value of integrating security tools</h2>
<p>Integrating security tools and establishing automated responses yields strategic value to the organization. Today’s <a href=”https://www.techtarget.com/searchsecurity/feature/Top-10-types-of-information-security-threats-for-IT-teams”>security threats</a> require quick identification and remediation. These interlaced layers of security give precisely that.</p>
<p>Integrated security tools improve visibility and eliminate gaps at endpoints, on networks and in cloud environments. This visibility illuminates threats and vulnerabilities — after all, you can’t fix what you don’t know about.</p>
<p>Yet, improving identification is only one facet of visibility. Better visibility also reduces the number of false positives — and subsequent <a href=”https://www.techtarget.com/whatis/definition/alert-fatigue”>alert fatigue</a> — generated by logging services, local event viewers, users and other services. Integrated security tools help correlate and collate alerts, ensuring accurate and timely information.</p>
<p>The result is strategic benefits any IT leader can appreciate. These include reduced risk exposure, improved resilience, improved compliance and greater operational efficiency.</p>

<h2 class=”section-title”><i class=”icon” data-icon=”1″></i>Real-world use cases</h2>
<p>SOAR, building on SIEM and EDR, helps organizations sidestep serious security concerns. Consider the following:</p>
<ul class=”default-list”>
<li><b>Insider threats.</b> Cross-tool enrichments enable quicker identification, context and responses.</li>
<li><b>Cloud workload protection.</b> Cross-platform, unified visibility and automated responses across on-premises and cloud environments ensure resilience.</li>
<li><b>Ransomware identifica
