Evaluate SIEMs on your own data. Not on a vendor's demo.

Fleak forks your real production telemetry to two or three candidate SIEMs at once, each in its native format. The bake-off compares detection, search, and cost on identical events, and the incumbent never notices.

  • Live production data
  • Side-by-side POCs
  • Native formats
  • Cost modeling
  • Zero impact on the incumbent

SIEM ingest reduction

modeled into every candidate's price

Most SIEM evaluations measure
the demo, not your environment.

A proof of concept onboards three sources, runs the vendor's sample detections, and prices a volume nobody will actually send.

Three sources, not three hundred

Onboarding every source into every candidate takes months, so the POC tests the easy ones and the hard ones show up after the contract.

Different data, different answers

Each candidate ingests a different slice at a different time. Detection results can't be compared because the inputs weren't the same.

Pricing on raw volume

Quotes assume you send everything. Nobody models what each SIEM costs once the noise is routed somewhere cheaper.

One stream, every candidate,
evidence instead of slides.

Fleak collects each source once and forks it to every SIEM in the evaluation, so the decision rests on identical data and real numbers.

Fork live data to every candidate

Send the same production events to Splunk, Microsoft Sentinel, Google SecOps, Palo Alto XSIAM, CrowdStrike NG-SIEM, or Elastic at the same time.

Native format for each

Every candidate receives events in the schema its content expects, so out-of-the-box detections get a fair test.

Your full source mix

AI-generated parsers onboard the long tail in days, so the evaluation includes the custom apps and legacy devices that usually get left out.

Real cost per candidate

Measure the volume each candidate would ingest after filtering and routing, and price it at each vendor's real rate.

No impact on the incumbent

The current SIEM keeps receiving exactly what it receives today. Evaluations run in parallel and end without a cleanup project.

Keep the winning pipeline

The pipeline built for the POC becomes the production pipeline for the winner. The migration starts the day you sign.

Synthetic data generator

Simulate realistic attack and benign telemetry to test candidates on scenarios your environment hasn't produced yet, without exposing production data.

Masked during the test

Sensitive fields are masked before data reaches any candidate, so a POC never turns into a compliance exception.

An evaluation scorecard

Score every candidate on the same checklist: detections fired, search speed, onboarding effort, and modeled cost.

Decide on evidence.

Same events, every candidate, side by side. Then keep the pipeline for the winner.

A bake-off
in four steps.

01 / Pick the sources

Choose the sources your detections depend on, including the ones vendors struggle to parse.

02 / Fork to candidates

Add each candidate SIEM as a destination in its native format. The incumbent is untouched.

03 / Run your detections

Run your own detections and hunts on identical data in every platform and compare the results.

04 / Decide and migrate

Choose on detection quality and modeled cost, then promote the winner's pipeline to production.

The Brain maps once.
Every candidate gets the same events.

The Brain generates a mapping per candidate from the same samples. The Muscle forks every event deterministically, so differences in the results come from the platforms, not from the data.

Candidates

  • Splunk
  • Microsoft Sentinel
  • Google SecOps
  • Palo Alto XSIAM
  • CrowdStrike NG-SIEM
  • Elastic

Three SIEM candidates, one 30-day evaluation.
What does each one receive?

Incumbent

Untouched

Keeps receiving every source exactly as today. Nobody re-points a forwarder.

Candidates

Live data

Each gets the same production events in its own format, including the long-tail sources.

Scorecard

Evidence

Detection hits, search speed, and modeled cost per candidate, measured on identical data.

Run the evaluation on your data, at your volume, with your detections. Then keep the pipeline for whichever platform wins.

"A SIEM evaluation is only as good as the data you feed it. Feed every candidate the same events, and the decision makes itself."
