2011年5月6日，Forrester发布了数据库审计与实时保护产品的市场分析报告（Forrester Wave）。

报告摘要： In Forrester's 147-criteria evaluation of database auditing and real-time protection vendors, we found that the market is rife with mature products. IBM(注：收购了Guardium), Imperva, and Sentrigo(注：被McAfee收购) lead the pack because of their strong user activity auditing, policy management, real-time protection, and application support capabilities as well as their forward-thinking strategies. Application Security, Oracle, and Fortinet are Strong Performers; their products have reporting, real-time detection and protection, and user-activity auditing capabilities that are slightly weaker than capabilities of the Leaders' offerings. However, all of the products we evaluated are mature database auditing and real-time protection solutions. Given this, rather than basing their choice of database auditing and real-time protection product on traditional auditing functions, application development and delivery professionals should base their decision on the more cutting-edge functionality, such as real-time attack activity blocking（***行为实时阻断）, privileged-user monitoring（特权用户监测）, drilldown analytics（下钻分析）, and centralization repository（集中管理）.

Forrester估计当前整个DAM市场规模约为6.5亿美元。整个市场相对较为成熟，过去几年并购不断，产品趋于向大厂集中。

其实，Forrester的这份报告实际上就是针对业界的DAM（Database Activity Monitoring）产品。下图是Forrester的Wave图：

另外，分析的这6个厂商外，还有一类DAM厂商，他们一般多以SIEM厂商的身份出现。
