A large prebuilt catalog
Hundreds of maintained connectors for SaaS and cloud security tools, tested daily against live APIs.
Fleak vs Monad. A catalog covers the head. Fleak covers the tail.
Monad is built around a catalog of prebuilt security connectors and templates. Fleak generates the parser and mapping for any source, repairs it when the source drifts, and runs it on an open-source engine.
- Any source, generated
- Drift repaired, not just reported
- Open-source engine
- Search and replay
Choose Fleak when
- You have in-house apps, legacy devices, or OT gateways that no connector catalog covers.
- You want schema drift repaired, not only flagged.
- You want an open-source execution engine you can inspect.
- You need search in place and replay from your own archive.
- Your data spans security, OT, aviation, and AI agents on one fabric.
Choose Monad when
- Your sources are mostly popular SaaS and cloud security tools in Monad's catalog.
- You want a self-serve trial and prefer to write JQ transforms yourself.
- You're a security vendor that wants Monad's embeddable connector catalog in your product.

Where Monad is strong.
Credit where it's due.
For the popular security tools, Monad's catalog gets data flowing fast, and its team ships connectors often.
Fast start for popular sources
Paste an API key and data flows. For mainstream tools, onboarding takes minutes, with a self-serve trial.
Security-specific features
OCSF templates, enrichment, Smart Optimizer, and drift alerts, all aimed at SIEM cost and SOC data.
Where Fleak is different,
past the edge of the catalog.
Most estates have a head of popular tools and a long tail nobody ships a connector for. Fleak is built for both.
The long tail, generated
The Brain generates parsers and mappings for in-house apps, legacy devices, and OT gateways, so you never wait for a vendor to build a connector.
Drift repaired, not just reported
When a source changes, Fleak repairs the mapping in minutes. The alert arrives with the fix attached.
An engine you can read
Zephflow, the execution layer, is open source under Apache-2.0. Inspect it, test it, and run it anywhere.
Search and replay
Keep the full-fidelity copy in your own storage, search it in place, and replay any slice into the SIEM when an investigation needs it.
Beyond security
OT telemetry, aviation operations data, observability, and AI agent traces run on the same fabric as your security logs.
From the edge to every destination
An edge agent, universal receivers, and API connectors feed one pipeline that routes every event by intent.
Bring the source that isn't in anyone's catalog.
That's where the difference shows.
Moving from Monad,
one source at a time.
01 / Inventory sources
List your Monad inputs and outputs. Fleak matches each to a connector or a generated parser.
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 / Add the long tail
Onboard the sources that were never in a catalog, with mappings generated in minutes.
FAQ
Frequently asked questions
How is Fleak different from Monad?
Monad is built around a catalog of prebuilt security connectors and JQ-based transforms. Fleak generates the parser and mapping for any source from samples, repairs mappings when sources drift, runs on an open-source engine, and extends beyond security.
Monad now detects schema drift. Doesn't that close the gap?
Monad's Schema Drift Detection alerts you when fields are added or change type. Fleak also repairs the mapping, with your approval or automatically, so the alert arrives with a fix attached.
Can Fleak connect to the tools we already pull from?
Fleak connects to the same SaaS and cloud APIs and to push sources such as syslog, HTTP, and OpenTelemetry. For anything missing, the Brain generates the connector or the parser.
Does Fleak have an OCSF template library?
Yes. 211 community OCSF templates on ocsf.ai, plus generated mappings for every source no template covers.
How does pricing compare?
Monad doesn't publish pricing and offers a 14-day trial. Fleak doesn't charge per connector or per event. Book a call for a quote.
Monad details are based on monad.com product, use-case, integration, and blog pages and Monad's public documentation, as of October 2026. Product names and trademarks belong to their owners.
Bring a source that isn't in any catalog.
30-minute working session. We'll generate its parser live and show you the OCSF output.
