Elastic Security
SIEM and XDR built on the Elastic Stack with open detection rules and endpoint integration.
Technical Architecture & Overview
Elastic Security turns the Elasticsearch platform into a SIEM, with data ingestion through Elastic Agent and Fleet, prebuilt detection rules mapped to ATT&CK, case management, and endpoint response through the same agent. The base is free and open under Elastic licensing, with paid cloud and enterprise tiers on top. Query DSL and the rule DSL make detection-as-code practical.
Targeted Technical Use Cases
Teams that want a SIEM they can run themselves, with full control over storage, scaling, and detection rules.
Evaluation & Trade-offs
Core Strengths
- +Free tier covers a working SIEM.
- +Huge integration ecosystem from the Elastic stack.
- +Detection rules are open and customizable.
Trade-Offs & Limitations
- -Storage engineering is your responsibility on self-managed clusters.
- -Licensing split between free and paid features needs review.
Defensive Security Application
Log aggregation, correlation, and endpoint response under one searchable data platform.
