A broad connector catalog
More than 500 catalog entries across cloud, on-prem, SaaS, and OT, with both agent and agentless collection.
Fleak vs DataBahn. Decide where your AI runs.
DataBahn puts autonomous AI agents on data in motion. Fleak keeps AI in the control plane, where it writes and repairs pipeline logic your team can review, and runs every event on an open-source deterministic engine.
- AI in the control plane
- Deterministic engine
- Open source
- Pipelines as code
Choose Fleak when
- You want AI to write and repair pipeline logic, not to act on production events.
- You want an open-source execution engine you can inspect and test.
- You manage pipelines as code, with public docs, an API, and Terraform.
- You want OCSF templates from an open community library.
- You also need to retire iPaaS pipelines for operations data, not just security logs.
Choose DataBahn when
- You want one vendor for collection, federated search, and an investigation agent.
- You need a very broad prebuilt catalog, including agentless collection.
- You prefer autonomous agents acting directly on data in motion.

Where DataBahn is strong.
Credit where it's due.
DataBahn ships a lot of platform, quickly, and its catalog and security content are broad.
Security-specific reduction content
A large library of prebuilt, security-specific reduction rules and filtering aware of SIEM use cases.
Search and agent access in one place
Federated search, an investigation agent, and a governed MCP gateway alongside the pipeline.
Where Fleak is different,
and what stays deterministic.
Both companies use AI to build and maintain pipelines. The difference is whether a model ever touches your production events.
AI that writes, not AI that acts
The Brain generates and repairs pipeline logic. A deterministic engine executes it, so every production event is processed the same way, every time.
An engine you can read
Zephflow, the execution layer, is open source under Apache-2.0. Inspect it, test it, and run it anywhere.
Pipelines as code
Every pipeline is a versioned YAML DAG you can export, review, and manage through the API, the SDKs, and Terraform.
An open template library
211 community OCSF templates on ocsf.ai that anyone can read, use, and improve.
Proven with AI SOC
In the Gruve benchmark, the same AI engine moved from Tier 1 to Tier 3 detection fidelity on Fleak-normalized data, with about 40% lower token cost.
Beyond security data
The same fabric retires iPaaS pipelines for operations data, as it did for 200+ pipelines at a major cargo airline.
Choose where your AI runs.
In the control plane, writing logic your team can review. Not in the data path, acting on production events.
Moving from DataBahn,
one source at a time.
01 / Inventory sources
List sources, rules, and destinations. Fleak maps each to a connector, a generated parser, or a routing rule.
02 / Run in parallel
Send the same sources through Fleak to a test destination and compare the output field by field.
03 / Cut over by source
Switch destinations one source at a time. Rolling back is switching back.
04 / Keep your logic
Bring reduction and routing logic along as versioned rules your team can read and review.
FAQ
Frequently asked questions
How is Fleak different from DataBahn?
DataBahn positions itself as an agentic data control plane, with AI agents acting on data in motion. Fleak keeps AI in the control plane: the Brain generates and repairs pipeline logic, your team reviews it, and an open-source deterministic engine runs it.
Does Fleak have AI agents like DataBahn's?
Fleak's Brain generates mappings, proposes routing and reduction, and repairs drift, and Fleak exposes an MCP server for your own agents. The difference is where AI runs: Fleak never puts a model in the path of production events.
Can Fleak replace DataBahn's reduction rules?
Yes. Fleak filters, deduplicates, samples, and routes by intent, and checks proposed cuts against your SIEM's active detection rules before they ship.
Is Fleak's engine really open source?
Yes. Zephflow, the execution engine, is licensed under Apache-2.0 and published on GitHub.
How does pricing compare?
Neither company publishes pricing. Fleak doesn't charge per connector or per event. Book a call for a quote.
DataBahn details are based on databahn.ai product, use-case, comparison, partner, and press-release pages as of October 2026. Product names and trademarks belong to their owners.
