CAUTION, some of you are surprised by the Prelude OSS's alleged "bad" performances:

  • Prelude OSS is intended for tests, evaluations and small infrastructures.
  • The OSS version performance is much lower than of the Pro version.
  • The  performance reduction increases at the same time that the number of events stored in base (and therefore the duration of use)
  • If you want to deploy prelude in an operational environment, we recommend that you go to the version SIEM or SOC after having evaluated the product thanks to the OSS version (the evolution is compatible and will allow you to keep your data)


The latest version of prelude OSS is available for download on the community site.
