SIEMese Twins: The Security Information Management and Security Event Management Markets

Published: 20 December 2007

ID: G00203371

Analyst(s): Bob Blakley


The security information and event management (SIEM) space has matured, consolidated, and differentiated over the last two years. Compliance, especially with the Sarbanes-Oxley Act (SOX) and Payment Card Industry (PCI) regulations, has been a primary driver of the SIEM market. In this report, Principal Analyst Bob Blakley discusses the forces that have driven vendors to distinguish security information management (SIM) from security event management (SEM) while continuing to offer both capabilities, and considers how such solutions can provide value to the enterprise.
