Websense, Inc. (NASDAQ:WBSN) today announced that IDC, the leading provider of technology analysis, recently named Websense the global leader of the Web security market with 21 percent share of the $1.2 billion dollar market—providing Web security protection and addressing emerging security challenges including Web 2.0 technologies and data loss prevention for organizations worldwide.

A growing market, IDC forecasts the Web Security market to grow from $1.2 billion in 2006 to $2.3 billion in 2011. Websense’s market share is more than the combined total market share of the next two largest Web security vendors.

According to the study, “Worldwide Web Security 2007-2011 Forecast and 2006 Vendor Shares” (Excerpt from IDC #210034, December 2007) by IDC Analyst Brian Burke, the demand and interest in Web security solutions is being fueled by corporate concerns about Internet threats that have become increasingly complex. Some of the key Web security trends identified by IDC include Web 2.0 technologies, blended Web-based threats and data loss prevention.

“The increasing popularity of Web 2.0 is opening the door for both inbound and outbound security risks. Coupled with the growing sophistication of blended Web-based attacks, IDC anticipates that Web security vendors will absolutely need to be able to monitor Web traffic bi-directionally,” said Brian Burke, program director for IDC’s Security Products program. “As the Web security leader, Websense is well-positioned to address the market trends we’ve identified—with a solution set that includes Web security, e-mail and hosted security as well as data loss prevention. We believe that Websense solutions will

continue to play a critical role in protecting organizations from emerging threats.”

In the study, IDC reports that today’s enterprises require a more holistic and integrated approach for Internet security—or what IDC calls a “Web security ecosystem” to combat emerging Web-based threats. IDC identified three areas in particular that vendors need to address: Web 2.0 – which includes collaborative technologies such as networking sites and wikis; blended malware – attackers are increasingly using blended malware from multiple threat vectors such as email and the Web to exploit vulnerabilities; and data loss prevention—as Web 2.0 environments open up networks for increased risk of data loss.

Websense is the only vendor that provides a combination of solutions to protect organizations from emerging Web security threats and address all three key areas of concern identified by IDC in the report: e-mail security, Web security and data loss prevention.

Customers worldwide look to Websense for protection from Web-based threats. Websense also announced today that long-time Websense Enterprise® customer Central Coast Community Healthcare has upgraded to and deployed Websense Web Security Suite™ software to protect the organization’s content and confidential patient data, users and network from emerging Web security threats.

“Websense was the first to forecast that the Web would become the largest threat vector and that hackers would increasingly use the Web to launch attacks for financial gain. We built Web security solutions to protect our customers worldwide,” said Leo Cole, vice president of marketing, Websense. “As the Web security leader, we are addressing today’s biggest security challenges, which include the proliferation of Web 2.0 technologies and protecting confidential data for our customers around the world.”
