After many months of work, we finally published the much-awaited content security Waves. On the Forrester SRM website, under the content security tab, you will be able to find three Wave documents: Email Filtering Wave, Web Filtering Wave, and Content Security Suites Wave.


We included ten vendors for all three Waves, Cisco Systems, Google, Marshal8e6, McAfee, Symantec/MessageLabs, Microsoft, McAfee/Secure Computing, Symantec, Trend Micro, and Websense. The intent of the Waves is to evaluate vendors who provide filtering functionality for multiple communication protocols (e.g., email, Web, and IM). Consequently, we did not include some of the pure-play vendors, such as Blue Coat Systems (for Web filtering) and Proofpoint (for email filtering), in the evaluations.


The evaluation of email filtering vendors revealed a mature market, characterized by strong appliance vendors with upstart cloud providers poised to win market shares. More specifically, we found that Symantec, Cisco Systems, and McAfee/Secure Computing lead the field because of their strong functionality and focused strategies. Google, Microsoft, Symantec/MessageLabs, and Websense are close behind with innovative cloud-based offerings. Trend Micro, Marshal8e6, and McAfee trail the field (see Figure1).

The evaluation of Web filtering market indicated a less than mature market, with

Websense and McAfee/Secure Computing lead the pack. Trend Micro, Cisco Systems, Symantec/MessageLabs, and McAfee are Strong Performers but fall short in certain areas of technology. Google, Marshal8e6, Microsoft, and Symantec lack either strong capability or cohesive vision, and trail the field (see Figure 2)

As the content security market continues to evolve, Forrester sees a growing market demand for consolidated content security suites rather than point products. In the third Wave, we evaluated content security suite offerings. The evaluation uncovered a budding market where only a small number of vendors reported adequate suite functionality. More specifically, we found that Websense leads the market because of its wide functionality and suite-oriented strategy. Symantec, McAfee/Secure Computing, and Trend Micro all have a clear strategy for product suites but are a notch down from Websense. Cisco, Symantec/MessageLabs, and Microsoft fall short in offering broad suite functionality. Google, McAfee, and Marshal8e6 trail the field for lacking either suite focus or comprehensive capabilities (see Figure 3).
