Websense Acquires Defensio

Acquisition extends content identification and classification capabilities of the Websense ThreatSeeker Network by providing visibility into spam posted as comments to social Web sites

SAN DIEGO, CA--(Marketwire - January 27, 2009) - Websense, Inc. (NASDAQ: WBSN) today announced the acquisition of Defensio, a technology platform focused on solving the problem of spam on the social Web. The acquisition immediately extends the content identification and classification capabilities of the Websense ThreatSeeker(tm) Network by providing visibility into spam posted as comments to social Web sites, including blogs, user forums and social networking sites. Websense will also enhance Defensio Web services so third-party Web 2.0 developers can embed Websense(r) content classification intelligence into their applications.

"This acquisition puts Websense years ahead of the security industry in Web 2.0 capabilities and intelligence," said Websense Chief Technology Officer Dan Hubbard. "We've already integrated Defensio intelligence into the ThreatSeeker(tm) Network, giving existing Websense customers broader protection from Web 2.0 security threats by making Websense products even more universal, accurate and effective. For example, Websense recently used Defensio-derived intelligence to detect that the popular presidential social networking Web site -- http://my.barackobama.com -- hosted links to malicious content within its user-generated blogs."

Criminals are adding Web 2.0 sites to their arsenal to spread spam and malicious code, boost search engine rankings and drive phishing and fraud scams. According to Websense Security Labs(tm) research, more than 95 percent of all Web posts on blogs, forums and other sites are unwanted content such as spam and malicious content. Additionally, more than 70 percent of all Web spam and unwanted content is hosted on legitimate sites that allow user-generated content.

"This technology acquisition extends our classification and identification abilities to these sources and helps Websense stay ahead of evolving threats. Defensio complements the capabilities of the Websense ThreatSeeker Network with adaptive algorithms. Websense also adds key security data enhancing Defensio." Commitment to Developer and User Communities

Websense remains committed to the Defensio developer community and plans to support and enhance the platform for personal users, as well as for commercial use. The company also plans to continue to offer the comment spam filter at no charge for personal use, while offering a new six month commercial trial at no cost.

"The combination of Defensio and Websense is a coup for Web 2.0 developers looking for strong anti-spam and security capabilities," said Carl Mercier, who founded Defensio and has joined Websense as director of software development. "Imagine if Web 2.0 developers could access an API so their applications could determine if user-generated content is malicious or unwanted -- without having to embed anything in their applications or products. We see strong potential to partner with social networking platforms, enterprises and hosting providers to enable advanced Web 2.0 security with the Defensio solution."
