AlienVault OSSIM vs Masergy comparison

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.

The Masergy SIEM+ solution captures and analyzes activity logs from firewalls, host Intrusion Detection/Prevention agents, Microsoft Windows events, and other syslog-producing devices. This log capture enables real-time, sophisticated rules-based analysis, correlation, alerting, monitoring and reporting. And we've integrated Masergy managed premise and cloud based firewalls and most industry leading commercially available firewalls, switches and routers to enable automatic and on-demand blocking of malicious traffic.
