Designed for the enterprise, the Barracuda Web Filter enables you to set up custom policies for particular user and groups across customizable time ranges. The Barracuda Web Filter integrates with popular LDAP directory servers, such as Microsoft Active Directory, for both authentication and group membership information on which to apply custom policies. Sample uses of group policies include: - Restricting access to job board Web sites to only the Human Resources group - Defining separate policies for teachers and students at a school - Enabling compliance officers unrestricted access to the Web for investigation - Providing external instant messaging (e.g., AIM) access only to specific users or groups - Restricting personal Web browsing to non-working hours - For organizations that do not utilize directory servers, policies can be defined for unauthenticated users as a whole, locally defined users and groups, or network IP address ranges.
Best of Breed Spyware Protection The Barracuda Web Filter employs a unique approach to integrate gateway and desktop spyware protection strategies. In providing Web security at the gateway, the Barracuda Web Filter prevents new spyware and virus infections as they attempt to penetrate the network. In addition, the Barracuda Web Filter facilitates automatic removal of spyware from previously infected Windows computers with the included Barracuda Spyware Removal Tool, an ActiveX control that can be served up automatically upon detection of spyware protocol activity (i.e., “phoning home.”) By adaptively targeting those machines that are infected, the Barracuda Web Filter provides widespread protection and removal without requiring preloaded client software on every machine on the network.
Easy to Use With no client software to install and no modifications required to your network, the Barracuda Web Filter is easy to deploy. It has an intuitive user interface for maintenance and monitoring, making it a virtually maintenance-free solution. Even system updates are made automatically by Barracuda Central, an advanced 24/7 security operations center where engineers work continuously to catalog sites used in personal Web browsing and to provide the most effective methods to combat the ever changing spyware variants. Updates are performed hourly so that your Barracuda Web Filter can provide ongoing enforcement of your Internet usage policy and protection of your network.
Affordable Large and small organizations alike demand solutions that are affordable not just today, but also in the future as they grow. With no per user license fee, the Barracuda Web Filter is the most affordable content filtering, application blocking, and anti-spyware solution available.
Barracuda Web Filter Features While the Web has certainly proven to be a powerful tool and technology, organizations worldwide have recognized the need to create policies around its usage in the workplace. Analysts estimate that 70% of browsing to pornography sites happens during normal business hours and about 30-40% of overall Internet usage in the workplace is not related to business. While many Web sites targeted at business usage provide safe and secure business environments, an increasing number of Web sites and Internet applications targeting personal usage are hosts to spyware, viruses, and other Internet threats. As such, unauthorized personal Web browsing poses not only a threat to personal productivity but to the security of the network as a whole. The Barracuda Web Filter is a complete content filtering and application blocking solution designed to enforce acceptable Internet usage policies by blocking access to objectionable content and unauthorized Internet applications. At the same time, the Barracuda Web Filter includes award-winning protection against Internet threats.
Comprehensive Content Filtering The Barracuda Web Filter combines multiple techniques, including URL filtering, URL rewriting, and MIME type blocking to provide powerful control over policies covering Web site usage. Capabilities include: - URL filtering by content category. You can define policies that restrict or allow Web sites based on their categorization. The Barracuda Web Filter includes definitions for 58 content categories, including pornography, violence, hacking, sports, news, dating, and chat sites. - URL filtering by domain name or URL pattern. You can customize your content filtering policy to restrict certain Web sites, or look for specific patterns in Web site addresses. Advanced administrators can specify URL patterns to block using the very powerful UNIX regular expression (regexp) syntax - Image Safe Search integration (URL rewriting). The Barracuda Web Filter takes advantage of the “safe search” content filtering capabilities built into image search engines, such as Google, Yahoo, and MSN. If enabled, the Barracuda Web Filter Image Safe Search feature rewrites URLs for these image search engines to include the URL parameters that restrict display of objectionable content in cached image search results. - File type blocking. You can define policies to restrict downloading of files over the Web based on their MIME types. For example, to block downloads of executables, you can block MIME type application/octet-stream. These controls can be combined to govern Internet usage to increase productivity, reduce exposure to offensive material, and to prevent visits to sites that could compromise security.
Internet Application Blocking Beyond the standard HTTP proxy solution, the Barracuda Web Filter also enables you to enforce policies governing usage of applications that access the Internet. Features include: - Instant Messaging (IM) Blocking. The Barracuda Web Filter enables you to set policy governing usage of public IM clients, including AIM, ICQ, Yahoo! Messenger, and MSN Messenger, and ICQ. These public IM clients can not only provide means for unmonitored communications, but their security vulnerabilities are often the target of those in the hacking community. Blocking public IM communications outright is one strategy to secure information flow and increase network security. - Application Blocking. In addition to IM applications, the Barracuda Web Filter includes policies for popular applications that access the Internet, including Internet music applications, software updaters, and popular browser toolbars. - IP and Port Blocking. You can customize your own IP blocking policies based on any combination of source or destination network IP address ranges and ports. One common usage of this feature is to prevent compromised machines from accessing the Internet. - The combination of Web and other Internet application blocking techniques enables you to define and implement complete Internet usage policies for your organization.
Advanced Policy Creation Because different rules may apply to different constituencies in your organization, the Barracuda Web Filter supports extremely granular applications of policies by user, group, or IP address range. It also supports time-based policies. Features include: - Default guest and user policies. For rapid deployment, the Barracuda Web Filter comes preconfigured with default guest (unauthenticated user) and known user (authenticated user) policies. You can easily customize default policies for content filtering and application blocking with simple easy-to-use Web forms. - User and group policy exceptions. You can customize policies by defining exceptions on top of the default policies. Policy exceptions can apply to content filtering and application blocking rules, and they can apply to specific users, groups, or network IP address ranges. For example, you can set a default policy to block Web access to job sites but create an exception for the Human Resources group to allow them. - Integration with LDAP directory servers. The Barracuda Web Filter integrates with popular LDAP directory servers, including Microsoft Active Directory, IBM Lotus Domino Directory, and Novell eDirectory. This integration provides the Barracuda Web Filter with real-time access to user and group membership managed by the directory server. You can define policies that apply to LDAP users and groups. - Integration with Windows Domain Controllers. Included with the Barracuda Web Filter is the Barracuda DC Agent, software that can be installed on your Windows Domain Controller. This software provides the Barracuda Web Filter with the username logged at each IP address, and it enables proper application of policy without requiring any user intervention and without a separate login. - Local users and groups. For sites that do not use directory servers or who wish to define policies for users and groups not managed by the directory server, the Barracuda Web Filter supports the creation of local users and groups on which to apply policy. - Network IP address groups. You can define policies that only apply to certain network IP address ranges or subnets. - Warning policies. The Barracuda Web Filter enables you to define policies for Web access that present users with a block page but allow them to proceed after being warned. Warning policies are useful for reminding users about sites which may violate corporate Internet usage policy without blocking them outright. - Web traffic monitoring. You can define policies for monitoring specific Web site categories, domain names, or URL patterns without presenting block pages to users or preventing access. Monitoring is useful to assess the potential impact of new policies prior to implementing access restrictions on the user community. - Time-based policy exceptions. You can define policy exceptions for both content filtering and application blocking based on time-of-day. For example, you can set a default policy to block access to sports sites but to allow browsing during non-working hours. - The Barracuda Web Filter was designed with ease of deployment in mind. With default policies, even organizations new to Web filtering can get started quickly. Organizations with more advanced filtering requirements can take advantage of advanced policy exceptions and integration with enterprise infrastructure.
