The Webroot AntiSpyware Corporate Edition (WASCE) 3.5.1 release allows customers to sample Webroot’s new Web Security SaaS, a hosted service that filters Internet traffic through Webroot data centers, where malicious threats and unwanted content are blocked before reaching the corporate network. To implement this filtering service, administrators can silently deploy a Desktop Web Proxy plug-in during client installation.
Later, they can configure the proxy service to work with browsers and turn on Web
Security SaaS capabilities on a group-by-group basis.
The Desktop Web Proxy plug-in manages transparent authentication on corporate desktops and laptops. As it passes HTTP and HTTPS traffic from Web-enabled applications to the Webroot filtering service, it adds the user’s authentication information to the Web requests and enables the filtering service to identify traffic accurately.
Fixes included in Webroot AntiSpyware Corporate Edition 3.5.1
Numerous performance and technical improvements were added as outlined below:
 Improvements to Active Directory integration resolving some AD login issues to the
Admin Console, as well as viewing and installing clients from the Client


Install/Uninstall screen under the AD View tab.
Database performance improvements to limit the growth of the database and transaction log.
Additional improvements to the Webroot Client to further address the engine failure issues.
