Ran Elastic Security (formerly Elastic Endgame) for 2.5 years. Switched to CrowdStrike Falcon Complete six months ago. This is a pragmatic, operational comparison.
**Elastic Strengths:**
* **Cost-effective data ingestion.** Own your data, no per-GB tax from the security vendor.
* **Deep, custom correlation.** If you have the resources to build and maintain rules.
* **Integrated stack.** SIEM and endpoint telemetry in one place is conceptually clean.
**Why we moved:**
The operational overhead became unsustainable.
* **Agent reliability.** Constant tuning of Elastic Agent/Endpoint for performance conflicts and resource spikes. Our standard config:
```yaml
agent.limits:
cpu: 2
memory: 400
connections: 80
```
Still had issues on high-I/O servers.
* **Detection engineering burden.** Out-of-the-box rules are a starting point. Tuning false positives and building new detections required a dedicated analyst. CrowdStrike's threat graph and IOAs work immediately.
* **Managed hunting is not their core.** With Falcon Complete, we get 24/7 managed hunting and response. Elastic's offering felt like an afterthought.
**Bottom line:** Elastic is a powerful toolkit for teams with deep engineering and SecOps resources. CrowdStrike is a refined product for operational teams that need reliability and a managed component. You're paying for the tool vs. paying for the outcome.
