Our Verdict
Choose Elastic Security if you want open-source flexibility, need to combine security and observability on one platform (Elastic can handle logs, APM, and SIEM on the same cluster), or have engineering resources to customize detections and dashboards. Self-hosted Elastic Security has no per-GB ingestion fees.
Choose Microsoft Sentinel if you prefer a fully managed SaaS SIEM without infrastructure management, run a Microsoft-heavy environment with native Azure/M365 integrations, or need enterprise security with Microsoft's threat intelligence and compliance features baked in.
Frequently Asked Questions
01 Is Elastic Security open source?
Elastic's core (Elasticsearch, Kibana) is source-available under the Elastic License 2.0. Basic security features are free; advanced features (machine learning, detection rules, endpoint protection) require a paid subscription starting at $95/month per node. Kibana ECS and detection rules are freely available on GitHub.
02 Can Elastic Security replace Microsoft Sentinel for a Microsoft shop?
It can, but with more integration work. Elastic has connectors for Azure AD, Microsoft 365, and Defender, but they require manual configuration vs Sentinel's native one-click integration. For Microsoft-heavy environments, Sentinel's zero-configuration Microsoft integration is a significant advantage.
