Every endpoint, application, cloud instance, and network device generates logs. These logs contain valuable clues about what is happening inside the environment, which is why organizations often turn to log aggregation platforms. But a growing and concerning trend is emerging: many companies are using log aggregators as SIEMs.<\/p>\n<p>At first glance, it might seem efficient to make log aggregators do double duty. After all, they centralize logs, store massive data volumes, and make search easy. But the truth is that using log aggregators as SIEMs introduces blind spots, weakens detection capability, slows incident response, and adds unnecessary cost in the long run.<\/p>\n<p>This blog explores why enterprises take this shortcut, the dangers behind it, and why a <strong><a href=\"https:\/\/www.newevol.io\/product\/cyber-security-information-event-management.php\">modern SIEM<\/a><\/strong> like NewEvol is necessary for real-time security.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_66_1 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title ez-toc-toggle\" style=\"cursor: pointer\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #0a0a0a;color:#0a0a0a\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #0a0a0a;color:#0a0a0a\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 eztoc-toggle-hide-by-default' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.newevol.io\/resources\/blog\/why-log-aggregators-used-as-siems\/#1_Why_Log_Aggregators_Became_the_Easy_Shortcut\" title=\"1.

Why Log Aggregators Became the Easy Shortcut<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Organizations adopt log aggregators as SIEMs primarily due to convenience and familiarity. Log platforms like ELK, Splunk, Graylog, and others are already widely used for IT monitoring, troubleshooting, and visibility. Because they are designed to ingest high volumes of logs and offer flexible search, IT teams assume they can perform security functions too.<\/p>\n<p>Several factors contribute to this trend:<\/p>\n<h3><span class=\"ez-toc-section\" id=\"11_Lower_Immediate_Cost\"><\/span><span style=\"font-size: 70%;\">1.1 Lower Immediate Cost<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If an organization already uses a log aggregator for DevOps or IT analytics, repurposing it for security feels like a &ldquo;free upgrade&rdquo;. Procurement teams see an easy way to avoid additional licensing and product purchases.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"12_Ease_of_Deployment\"><\/span><span style=\"font-size: 70%;\">1.2 Ease of Deployment<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Log aggregation tools are straightforward to deploy. Many have open-source roots, plug-and-play connectors, and simple dashboards. For a team short on time or skills, this feels more manageable than rolling out a full SIEM.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"13_The_Misbelief_That_Logs_Security\"><\/span><span style=\"font-size: 70%;\">1.3 The Misbelief That Logs = Security<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Many organizations believe that as long as logs are collected centrally, they are secure. But centralization alone does not equal threat detection. Without correlation, analytics, and context, logs remain passive data.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"14_Skill_Gaps_in_Cyber_Teams\"><\/span><span style=\"font-size: 70%;\">1.4 Skill Gaps in Cyber Teams<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A large number of US organizations face a severe shortage in SOC talent.
