Log Routing and Optimization -- Cribl Alternatives
Log routing and optimization is the core use case for security data pipelines — collecting logs from diverse sources, filtering out low-value data, transforming formats, and routing the right data to the right destination. Organizations use data pipelines to reduce log volume by 40-70%, cutting downstream SIEM and storage costs while ensuring security-relevant data reaches the tools that need it. These Cribl alternatives offer different approaches to log routing, from open-source collectors to AI-powered optimization.
Inventory all log sources across your environment including firewalls, endpoints, cloud services, applications, and network devices. Map each source to its appropriate destination — SIEM for security-relevant data, data lake for long-term storage, or archive for compliance retention.
Install collection agents (Fluentd, Fluent Bit, Vector, or vendor-specific agents) across your infrastructure. Configure agents to forward data to your central pipeline for processing. Use lightweight agents like Fluent Bit for containerized environments.
Define routing rules that direct data to appropriate destinations based on source type, content, severity, and business value. Route security-relevant logs to your SIEM, verbose debug logs to cheaper storage, and compliance-required logs to long-term archive.
Configure data reduction rules to filter out low-value fields, deduplicate events, sample verbose sources, and aggregate repetitive logs. Apply format transformations to normalize data into schemas expected by downstream tools.
Deploy monitoring for pipeline throughput, latency, error rates, and data reduction ratios. Track cost savings by measuring data volume before and after pipeline processing. Set alerts for pipeline failures or unexpected data volume changes.
Free (open source, MPL 2.0)
The highest-performance open-source option for log routing, with Rust-based throughput that handles massive data volumes at minimal resource cost. VRL transforms provide powerful routing logic with end-to-end delivery guarantees.
Free (open source) / Commercial support via vendors
The most widely adopted open-source log collector with 800+ plugins covering virtually every source and destination. CNCF-graduated status and Kubernetes-native deployment make it the default choice for cloud-native log routing.
From $0.10/GB processed / Enterprise custom
A managed pipeline built on Vector that provides enterprise support and monitoring for log routing workflows. Best for Datadog customers who want managed routing with built-in sensitive data detection.
From $0.80/GB ingested / Enterprise custom
Combines log management with pipeline routing in a single platform, providing both routing capabilities and built-in log search and analytics. Ideal for teams wanting a unified tool for collection, routing, and analysis.
Custom pricing based on data volume
AI-powered optimization automatically identifies low-value logs and routes high-value data to appropriate destinations. Best for teams that want intelligent routing without manually configuring complex pipeline rules.

Data pipelines typically achieve 40-70% data reduction through filtering unnecessary fields, deduplicating events, sampling verbose sources, and aggregating repetitive logs. The exact reduction depends on your data sources — verbose sources like DNS logs, firewall connection logs, and debug-level application logs offer the highest reduction potential. Security-critical events should not be reduced, only enriched and routed efficiently.
Open-source tools like Fluentd and Vector are excellent for straightforward log collection and routing, especially in Kubernetes-native environments. Commercial tools like Cribl add value when you need advanced data reduction, a GUI pipeline designer, data replay, and enterprise support. If your primary need is collecting and forwarding logs to a few destinations, start with open source. If you need to significantly reduce data volumes and optimize costs, a commercial pipeline may deliver faster ROI.
No. Data pipelines route and transform data but do not provide detection, correlation, alerting, or investigation capabilities. A pipeline sits in front of your SIEM, optimizing the data that flows into it. By reducing low-value data before it reaches your SIEM, a pipeline can dramatically cut SIEM licensing costs while ensuring security-relevant data is preserved for detection and analysis.
Production-grade pipelines include buffering and retry mechanisms to prevent data loss during outages. Vector provides end-to-end acknowledgements and disk-based buffering. Fluentd includes configurable buffer plugins with retry logic. Cribl offers persistent queues and data replay. When evaluating pipelines, verify their data durability guarantees and configure appropriate buffer sizes for your expected outage recovery time.
