Blumira’s free SIEM tier is genuinely useful for small teams testing cloud-native detection. Expel requires enterprise-level commitment and budgets.

Features & Deployment

Both operate as cloud services. Blumira emphasizes simplicity: automated detections, playbooks, 24/7 support, and honeypots in a single cloud SIEM. Expel is a managed detection and response (MDR) platform that sits across your existing cloud, endpoint, and SIEM tools—vendor-agnostic and built on a “transparent workbench” for investigators to see findings in context.

Deployment advantage: Blumira wins on speed—it’s plug-and-play for Microsoft 365 and cloud apps. Expel requires deeper integration with your existing security stack but offers broader coverage if you already own tools.

Ratings & Verdict

G2 score4.6/5 (120 reviews)4.7/5 (90 reviews)
Our score8.17.5

Choose Blumira if you’re a lean team, startup, or MSP wanting a free, easy-to-deploy SIEM with built-in detections. The 14-day trial and free tier let you validate quickly.

Choose Expel if you’re mid-market/enterprise with existing security tools (Okta, AWS, CrowdStrike, etc.) and want a transparent MDR vendor to investigate and automate responses across them—vendor lock-in isn’t a concern, and budget exists.
