Elastic Security
Elasticsearch's search power, pointed at security logs instead of web pages
What it is
About Elastic Security
Elastic Security combines SIEM (security information and event management), endpoint protection and threat-hunting capabilities on top of the open-source Elastic Stack (Elasticsearch, Kibana), letting security teams ingest huge volumes of log and telemetry data and search it in near real time. It competes with Splunk and Microsoft Sentinel in the SIEM space and with CrowdStrike/Defender in endpoint protection, with the differentiator being its open-source foundation and flexible, scalable data architecture. Detection rules, dashboards and threat-hunting queries are core daily tools for SOC analysts using it.

How to learn it
Learning Resources
Review Elastic's official documentation and free Elastic Security fundamentals training
Watch Elastic's YouTube channel and community webinars
Pursue Elastic Certified Analyst / Engineer certification paths
Set up a free local Elastic Stack instance and practise building detection rules against sample log data
Pro Tip
Elastic's free tier is genuinely usable for learning the SIEM query language (KQL/EQL) — build detection rules against your own home network logs before touching a paid enterprise deployment.
