Best Security Data Pipelines
The security data pipeline tools and vendors worth knowing in 2026, compared on cost reduction, integrations, deployment and automation. Listed neutrally, with no editorial scoring or rankings.
What this shortlist looks at
Cost and data reduction
How effectively the tool filters, samples and routes telemetry to cut SIEM and storage spend without losing the data detection relies on.
Integrations and routing
Breadth of sources and destinations, and the flexibility of routing, transformation and enrichment.
Deployment model
SaaS, self-managed or hybrid; agent versus agentless; and OpenTelemetry support.
Automation and AI
How much of pipeline tuning the tool automates versus manual rule-writing.
Licence model
Open source versus commercial, and the operational trade-off each implies.

Tools listed here
Azure Data Explorer
Best for Azure-native analyticsMicrosoft analytics service for large-scale telemetry and log analytics on Azure. Strong where the estate is already Azure-centric.
Microsoft's fast data analytics service for real-time analysis of streaming security data
CeTu
Best for AI-native data engineeringAn AI-native approach to security data engineering, automating much of the routing and transformation work. An early-stage entrant in the cost-reduction space.
AI-powered security data pipeline for intelligent log ingestion, enrichment, and routing at scale
Cribl
Best for vendor-neutral routing at scaleThe market-leading observability and security data pipeline. Routes, reduces and transforms telemetry to any destination with broad source and sink support. The incumbent most teams compare alternatives against.
Security data pipeline platform for routing, reducing, and transforming observability data
Datadog Observability Pipelines
Best for Datadog-centric teamsNative to the Datadog platform, processing logs and metrics before ingestion. Convenient and well-integrated if you already run Datadog, though less vendor-neutral than standalone pipelines.
Managed observability pipeline for routing and transforming telemetry data at scale
Fluentd
Best established open-source collectorA widely used CNCF open-source log collector with a large plugin ecosystem. Mature and ubiquitous, often paired with a commercial pipeline for managed routing.
Open-source unified data collector and log aggregator from the CNCF ecosystem
Mezmo
Best for log management plus pipelineCombines log management with a telemetry pipeline, with responsive routing, filtering and transformation. A good fit for teams that want both in one product.
Log management and observability pipeline platform with intelligent data routing
Observo AI
Best for AI-driven optimisationAn AI-native pipeline that automatically shapes and reduces telemetry to cut SIEM and storage cost. A newer challenger focused on automation over manual rule-writing.
AI-powered security data pipeline for intelligent data optimization and cost reduction
Realm.Security
Best for an AI-native security data fabricFilters and routes security telemetry for the SOC, aiming to cut SIEM cost and noise while improving detection-data quality. AI-native, focused squarely on security use cases.
Security data fabric platform for intelligent routing and optimization of security telemetry
Sawmills
Best for agentic cost reductionA 2024 entrant using an AI agent to filter telemetry before ingestion, built on the OpenTelemetry Collector to stay vendor-neutral and cut observability spend.
AI telemetry pipeline that filters and optimises logs, metrics and traces pre-ingestion to cut observability cost.
Splunk Data Stream Processor
Best for Splunk-centric enterprisesSplunk Data Stream Processor handles streaming transformation and routing, a native fit for organisations already standardised on Splunk.
Splunk's real-time stream processing engine for data optimization and routing
Tenzir
Best for security-focused open sourceAn open-source data pipeline built specifically for security and SOC workflows, with a security-data-first design.
Open-source security data pipeline with native support for security-specific data formats
Vector
Best open-source pipelineA high-performance open-source pipeline (originally by Datadog). Vendor-neutral routing and transformation with no licence cost, in exchange for running it yourself.
High-performance open-source observability pipeline built in Rust by Datadog
