Graylog is a mature log platform with a loyal user base, and Graylog Open is a solid way to centralise logs on your own hardware. Teams usually start looking elsewhere for one of two reasons: running the stack underneath (a search cluster plus MongoDB) has become a job of its own, or they need security features such as correlation and anomaly detection that sit in the paid Security tier.
This comparison weighs the alternatives on what decides the choice: who runs the platform, whether security monitoring is included, how pricing behaves as volume grows and under which jurisdiction your logs fall.
Why teams look for a Graylog alternative
- Operations: you size, patch and upgrade the search cluster and MongoDB yourself, and storage growth means cluster work.
- Security features are a separate purchase: correlation, anomaly detection and investigation workflows live in Graylog Security.
- Detection content: building and maintaining rules for new threats takes time a small team rarely has.
- Scaling: higher event volumes ask for more nodes, more tuning and more monitoring of the log platform itself.
The alternatives
1. LogPulse
A managed log management and SIEM platform on ClickHouse, hosted at Scaleway in Amsterdam. Security monitoring is in every plan, Free included, with over 690 tested Detection Hub rules mapped to MITRE ATT&CK, risk-based alerting and Sigma import. Pricing is flat per plan instead of per GB. Enterprise can also run on-premises on OpenShift, Kubernetes or Red Hat Enterprise Linux.
Best for: Teams that want to stop running a log cluster and get a SIEM in the same subscription.
2. Elastic Security
SIEM on the Elastic Stack, self-hosted or on Elastic Cloud. Strong search and a large public rule repository. You still size and tune a cluster when self-hosting; cloud pricing is resource- or usage-based.
Best for: Teams with Elasticsearch expertise in-house.
3. Wazuh
Free and open-source security platform with agents for host monitoring, file integrity monitoring and vulnerability detection. No licence cost, but the same operations burden as a self-hosted Graylog.
Best for: Teams with more engineering time than budget that want host security.
4. Grafana Loki
Open-source log aggregation that indexes labels rather than content, which keeps storage cheap. Good for operational log viewing next to Grafana; not a SIEM.
Best for: Kubernetes teams on Grafana that mainly need operational logs.
5. Splunk Enterprise Security
The most mature SIEM, with a huge app ecosystem and the SPL query language. Ingest- or workload-based licensing makes it the most expensive option here by a wide margin.
Best for: Large SOCs with dedicated Splunk engineers.
6. Microsoft Sentinel
Cloud SIEM on Azure with deep Microsoft 365 and Defender integration. Metered per GB plus retention and automation, which makes the bill hard to predict.
Best for: Microsoft-centric organisations with Azure skills.
