AlienVault OSSIM is trusted by security professionals across the globe

AlienVault® OSSIM™ is a feature-rich, open-source security information and event management (SIEM) that includes event collection, normalization, and correlation. AlienVault OSSIM was launched by engineers because of a lack of available open-source products and to address the reality many security professionals face, which is that a SIEM, whether it is open source or commercial, is no good if it does not provide security visibility.

Our Open Source SIEM (AlienVault OSSIM) addresses this reality by providing one unified platform with many of the essential security capabilities you need like:

  • Asset discovery
  • Vulnerability assessment
  • Intrusion detection
  • Behavioral monitoring
  • SIEM event correlation

AlienVault OSSIM leverages the power of the AlienVault® Open Threat Exchange® (OTX™) by allowing users to both contribute and receive real-time information about malicious hosts. In addition, we provide ongoing development for AlienVault OSSIM because we believe that everyone should have access to sophisticated security technologies, to improve the security of all. From the researchers who need a platform for experimentation and the unsung heroes who can't convince their companies that security is a problem, AlienVault OSSIM offers you a chance to increase security visibility and control in your network.
