It is a tool for driving IT security. Prelude SIEM collect and centralize information about company's IT security to offer a single point of view to manage it. Thanks to its logs and flows analyzer, Prelude SIEM create alerts about intrusions and security threats in the network in real time. Prelude SIEM provide multiple tools to do forensic and reporting on Big Data and Smart Data to identify weak signals and Advanced Persistent Threat (APT). Finally, Prelude SIEM embeds all tools for the exploitation phase to make works easier for operators and help them on risk management.
While a malicious user (or software) may be able to evade the detection of a single IDS (NIDS, HIDS, etc.), it becomes exponentially more difficult to get around the defenses when there are multiple protection mechanisms. Prelude SIEM comes with a large set of sensors, each of them monitoring different kind of events. Prelude SIEM permits alert collection to WAN scale, whether its scope covers a city, a country, a continent or the world.
Prelude SIEM is a SIEM system capable of inter-operating with all the systems available on the market. It implement natively the Intrusion Detection Message Exchange Format (IDMEF, RFC 4765) format which start to be demanded all around the world. In this way, it is natively IDMEF compatible with OpenSource IDS: AuditD, Nepenthes, NuFW, OSSEC, Pam, Samhain, Sancp, Snort, Suricata, Kismet, etc. but anyone can write its own IDS or use some of the 3rd party sensors available, given Prelude SIEM's open APIs and libraries.
Since 2016, with the "Prelude IDMEF Partner Program", Prelude SIEM is now also IDMEF compatible with many commercial IDS.
Prelude SIEM provides all SIEM functions through three modules : ALERT (SEM), ANALYZE ans ARCHIVE (SIM) and is so the only one true SIEM alternative on the market. Plus, Prelude SIEM promotes the use of IETF security standards through the SECEF project and the "Prelude IDMEF Partner Program".

Prelude SIEM collects, normalizes, sorts, aggregates, correlates and displays all security events regardless of the types of surveillance equipment. Beyond its capacity for processing of all types of event logs (system logs, syslog, flat files, etc.), Prelude SIEM is natively compatible with many IDS.
Prelude SIEM main characteristics are the following:
- Built on an open-source core (Python, C), light web client 2.0
- "Agent-less" operation
- Compliant with Intrusion Detection Message Exchange Format (IDMEF, RFC 4765), Incident Object Description Exchange Format (IODEF, RFC 5070), HTTP, XML, SSL standards
- Smart Data : Smart correlation of security events
- Big Data : Collect, Storage and index of logs
- Modular, flexible and resilient
- Hierarchical and decentralized architecture
Prelude SIEM Community versionEdit
Prelude SIEM OSS has been designed in a scalable way to simply adapt to any environment. it is free, public and open-source version (GPLV2) for small IT Infrastructures, tests and educational purposes.
The open-source version is composed of the following main modules:
- Manager: which receives and stores alerts into the database
- LibPrelude: connect each IDMEF agents to Prelude SIEM
- LibPreludeDB: high speed database insertion module
- Correlator: event correlation module
- LML (Log Management Lackey): detect and normalize important logs
- Prewikka : web Graphical User Interface (GUI)
These modules are the base of the ALERT module in the commercial version. The commercial version also add many functionalities to these modules and scale up the performances and architecture possibilities.
Prelude SIEM and Prelude SOCEdit
Prelude SIEM (commercial version) is scalable, professionally usable and high performance version of Prelude, for real-world environments. Prelude SOC is fully scaled version, mainly for SOC (Security Operations Center) usage.
The commercials versions are organized like this:
- Prelude SIEM : SIEM for enterprise with modules: ALERTE, ANALYSE and ARCHIVE
- ALERTE : Storage, Detection, Normalization, Correlation, Aggregation, Real-time Notification
- ANALYSE : Analyze, Reporting and Compliance
- ARCHIVE : Storage, Indexation of logs and flows for forensic
- Prelude SOC : in addition of Prelude SIEM, it is possible to add more operationnals securuity modules to build a Security Operation Center (SOC)
- MAP : Real time cartography of the IT parc with security indicators. It is possible to drill down and made physical, logical or risk management representations.
- VULN : Vulnerability scanner based on OpenVAS. It is possible to use it inside the correlator to made cross-correlation
- ASSET : Asset management based on GLPi (assets, tickets, workflow, etc.)
- REPORT : Business Intelligence reporting.
