Welcome to NTSecurity.com
The Barracuda Web Filter, previously known as the Barracuda Spyware Firewall, provides content filtering, virus filtering, spyware download filtering, spyware communication blocking, spyware detection, and spyware removal from Windows desktop computers.
The Barracuda Web Filter includes 58 categories of Web sites that are updated regularly. These categories include Web sites known to include spyware, pornography, and other offensive materials. The Barracuda Web Filter blocks access to these sites so that problems, such as spyware downloads from these sites, are avoided.
Yes, the Barracuda Web Filter enables administrators to customize policies for specific users, groups, and IP address ranges in the organization. Administrators can also establish effective time ranges for those policies.
Sample uses for these capabilities include:
The Barracuda Web Filter integrates with popular LDAP compatible directory servers for user and group membership information. It also integrates with Windows domain controllers to facilitate transparent user authentication.
The Barracuda Web Filter supports any LDAP compatible directory server, including Active Directory, Domino Directory, eDirectory and Open LDAP.
There are three authentication mechanisms supported by the Barracuda Web Filter.
The Barracuda Web Filter enables administrators to restrict access by domain, URL pattern, content filter categories, image safe searching, MIME types and application.
If the Barracuda Web Filter is blocking a Web site that you need to access, it is possible to override the block by placing the URL or IP address on a whitelist.
While the original intent of the Barracuda Web Filter was to address the focused problem of spyware and virus protection at the gateway, thousands of Barracuda Web Filter customers purchased and deployed the product for broader content filtering applications.
With the introduction of advanced user, group, subnet, and time-based policy controls, Barracuda Networks renamed the Barracuda Spyware Firewall to the Barracuda Web Filter to better reflect both the current feature set and the actual usage in customer environments.
Despite the change in product name, Barracuda Networks remains committed to offering best-of-breed spyware protection as an important differentiator in the Web filtering marketplace.
Spyware poses tremendous security threats to organizations, including intellectual property theft, productivity loss, and privacy invasion. As such, Barracuda Networks broadly defines spyware as any software that when installed on your computer either delivers or communicates information without your knowledge or intention outside your computer. This is a very broad definition of spyware, but one that we believe, given the current plethora of problems with spyware, is necessary. This definition includes all malware, adware, keyloggers, toolbars, and many other categories of programs.
The Barracuda Web Filter both blocks access to known spyware sites and analyzes all downloaded files against its database of known spyware and known viruses. These databases are updated every hour with the latest spyware and virus definitions so that your network is always protected
Yes. The Barracuda Web Filter includes the Barracuda Spyware Removal Tool, an ActiveX control that removes spyware from Windows computers. When the Barracuda Web Filter detects spyware protocol activity ("phoning home"), it can automatically redirect the user's Web browser to a page that serves up the Barracuda Spyware Removal Tool. Spyware detection and removal definitions are updated hourly.
It is generally beneficial to layer security solutions. The Barracuda Web Filter is an effective gateway-based solution to act as a primary line of defense to both prevent spyware from entering the network and to remove spyware from desktop computers once it is detected on the network. The preponderance of spyware infection attempts can be effectively blocked at the gateway.
That said, adding an extra layer of protection with a traditional desktop spyware solution can be beneficial to prevent spyware infections in cases where spyware threats infiltrate through means other than the network, including via laptops, USB keys, CD-ROMs, or floppy discs.
The Barracuda Web Filter cannot protect users while that are working remotely unless they VPN into the corporate network. However, once the laptops reconnect to the corporate network, the Barracuda Web Filter can detect the spyware protocol activity, block it and serve up the Barracuda Spyware Removal Tool to clean the infected computer.
Any spyware infections that are not easily removed with the Barracuda Spyware Removal Tool or any traditional desktop spyware solutions may require that you re-image your machine.
The Barracuda Web Filter protects each link to the Internet; therefore organizations with multiple sites and links will need to purchase a separate unit for each Internet access point.
The Barracuda Web Filter will work in all common network configurations. The Barracuda Web Filter can sit in front of or behind the Internet firewall; however, we recommend that it be placed behind the organization's Internet firewall so NAT (Network Address Translation) doesn't interfere with identifying the systems that could potentially be infected.
The Barracuda Web Filter can work in conjunction with your proxy server, either as a cascading proxy server or in transparent mode. That said, we normally recommend replacing your proxy server with the Barracuda Web Filter.
The Barracuda Web Filter scans and filters port 80 (Web) for content filtering, spyware blocking, and virus blocking. The Barracuda Web Filter will analyze and block ALL ports for outgoing spyware communications and policy violations for other applications that access the Internet, such as Instant Messaging, media applications, and software updaters.
There is no software or hardware limit on the number of users connected to each unit and the recommended throughput capacities and concurrent user recommendations are based on typical performance. The model that will best suit your network's needs depends primarily on the type and amount of Internet traffic. Our trained Barracuda Networks sales representatives can help you determine which model is best suited for your needs.
The Barracuda Spam & Virus Firewall is designed to protect the email server and filter spam and viruses from all SMTP traffic entering the network via port 25. As such, the Barracuda Spam & Virus Firewall only protects the email stream. The Barracuda Spam & Virus Firewall does include blocking of spyware programs that are attached to email, however, it does not provide general blocking and detection of spyware like the Barracuda Web Filter does. The Barracuda Spam & Virus Firewall normally sits in front of your email server and receives and processes only your email stream. The Barracuda Web Filter, on the other hand, sits at your Internet gateway and processes ALL of your Internet traffic.
Because spyware threats and viruses change continuously, new spyware sites, spyware definitions, and virus definitions are automatically delivered to the Barracuda Web Filter through the Barracuda Networks Energize Updates subscription. Users can configure this feature to update hourly or daily. This process ensures that the Barracuda Web Filter is automatically up to date and does not require the administrator to make manual updates.
The Barracuda Web Filter has a Web-based interface for ease of use. In addition administrators can choose to receive system status information via email.
No. The Barracuda Web Filter has no per user licensing fees. 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 licensing fees, organizations can scale without having to worry about increasing costs – making the Barracuda Web Filter the most affordable anti-spyware solution available.
The Barracuda Networks Energize Updates subscription provides the latest spyware, content definitions, and virus updates. It is an essential part of purchase. In addition, we do provide multi-year subscriptions that can provide a cost savings to you.

Since there are no associated per user license fees, the Barracuda Web Filter does not impose limits on the number of users that can be protected by a given model. Rather, each model has a recommended range of users, termed concurrent users. This refers to the number of simultaneous users the device can service while maintaining optimal performance based on system resources and expected traffic volume. A significant increase beyond the recommended range could impact performance but will not prevent the device from active operation. Unlike solutions that have hard limits on the number of users, the Barracuda Web Filter is guaranteed to protect all network users. A Barracuda Networks sales representative can help you find the appropriate model to provide the best performance in your network.
