Graylog Security review
A packaged SIEM for lean and mid-sized teams that need analytics, cases, and response workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Graylog Security is a SIEM for lean and mid-sized security teams that need centralized log analytics alongside detection, investigation, response, and compliance capabilities. It extends Graylog’s log-management environment with entity-based risk scoring, machine-learning and UEBA anomaly detection, real-time correlation, dashboards, and searchable reports. Cloud, self-hosted, and API deployment options support cloud, on-premises, and hybrid operating models.
The published plan shows one Graylog Security tier at $18,000 per year, billed annually. That starting price is based on 10 GB per day of daily capacity or 100 GCUs of annual consumption, and licensing is tied to processed data volume. The platform connects with Amazon S3, Amazon EC2, Amazon EKS, Amazon PrivateLink, AWS Security Hub, Qualys, and Tenable Cloud. Organizations evaluating it should therefore size expected event volume and review how those integrations fit their existing AWS and vulnerability-management workflows.
Its strongest differentiator is the combination of risk scoring, UEBA, correlation, Sigma rule import, MITRE ATT&CK mapping, and automated case creation with investigation evidence collection. Guided response, automated workflows, custom watchlists, data-lake routing and tiering, selective retrieval, and AI-generated investigation reports extend the product beyond alert search. Security teams that want packaged detection content and case handling should find this breadth relevant. Smaller teams with modest log volumes or buyers seeking a no-cost entry tier may prefer a lower-commitment alternative, while cloud customers should account for contract-based retention terms when comparing deployments.
Graylog Security pros and cons
- Where it wins
- Entity-based risk scoring prioritizes threats for investigation.
- Automated cases collect evidence and support guided response workflows.
- Sigma support and MITRE ATT&CK mapping speed detection-content adoption.
- Where it doesn't
- Annual licensing starts at $18,000, which may exceed small-team budgets.
- Pricing scales with processed data volume, complicating forecasts as logs grow.
- Cloud retention terms are negotiated by contract rather than fixed in the plan.
