AlienVault OSSIM, Open Source Security Information and Event Management (SIEM), provides you with a feature-rich open source SIEM complete with event collection, normalization and correlation. Launched by security engineers because of the lack of available open source products, AlienVault OSSIM was created specifically to address the reality many security professionals face: A SIEM, whether it is open source or commercial, is virtually useless without the basic security controls necessary for security visibility.

Splunk Enterprise Security is a SIEM, log management, and IT operations analytics tool. The solution provides users with the ability to secure their information and manage their data in the cloud, data centers, or other applications. Splunk Enterprise Security also offers visibility from different areas, levels, and devices, rather than from a single system, thus, providing its users with flexibility. Splunk Enterprise Security can monitor data and analyze, detect, and prevent intrusions. This benefits users as it provides alerts to possible intrusions, helps users to be proactive, and reduces risk factors.
