AlienVault® OSSIM™ Reviews & Product Details

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.
