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.

12 tools listed|2026|No editorial scoring

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 analytics

Microsoft 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 engineering

An 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 scale

The 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 teams

Native 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 collector

A 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 pipeline

Combines 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 optimisation

An 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 fabric

Filters 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 reduction

A 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 enterprises

Splunk 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 source

An 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 pipeline

A 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

Frequently Asked Questions

A security data pipeline collects, filters, transforms and routes security telemetry (logs, metrics and traces) before it reaches a SIEM or data lake, to cut data volume, cost and noise while improving the quality of data that detection and response rely on.

Weigh cost and data reduction, how well it fits your existing SIEM and observability stack, the deployment model (SaaS, self-managed, open source), and whether you want AI-driven automation or full manual control. Run a proof of value on your real data before committing.

They overlap heavily. Observability pipelines such as Cribl, Datadog Observability Pipelines and Mezmo handle all telemetry; security data pipelines focus on SOC use cases like SIEM cost control and detection-data quality. Many tools serve both.
