Community| Welcome

Prelude OSS is a complete solution for security supervision to monitor modest size infrastructures. Originally created by Yoann Vandoorselaere, Prelude OSS is the open source SIEM reference since 1998. All sources and project documentation are available on the community website.

Caution: The performances of Prelude OSS does not allow to monitor a large infrastructure more than a few days: The limited performance of prelude OSS do not allow it to monitor a park important on a duration of more than a few days. In fact, the database performance decreases exponentially with the number of collected alarms.

How to contribute?

An open-source project cannot survive a long time without your contributions. There are several simple and easy ways to participate in the development of prelude OSS:

  • If you have developed/improved LML rules
  • If you have developed/improved the correlation rules and that they are generic enough
  • If you have developed a patch
  • If you have written an article on Prelude OSS

Thank you for your participation
