Web Filter

The Barracuda Web Filter is an integrated content filtering, application blocking and malware protection solution that is powerful, easy to use and affordable for businesses of all sizes.

The Web Filter enforces Internet usage policies by blocking access to Web sites and Internet applications that are not related to business, and it easily and completely eliminates spyware and other forms of malware from your organization. No more costly staff time lost repairing infected computers.

Powerful and Affordable

What really bothers management is not knowing what employees are doing on the web: How much time do employees spend on social networks or gaming sites? Is anyone downloading malware or pornography? Why is the Internet running slowly today? The Barracuda Web Filter gives administrators clear visibility into web activity to answer these important questions while blocking today's aggressive web threats.

With extensive policy tools for managing web access in the workplace and no per-user fees, Barracuda Web Filter is a powerful and affordable content filtering appliance with models designed for use in organizations of all sizes.




Integrated Spyware & Virus Protection

  • Blocks Known Spyware Sites

    As a first line of defense, the Barracuda Web Filter blocks access to a database of sites known to host spyware. The database automatically updates in real time through Barracuda Energize Updates.

  • Blocks Spyware Downloads

    The Barracuda Web Filter blocks spyware from being installed without the user's knowledge - also known as drive-by installs or downloads.

  • Integrated Antivirus Protection

    By using dual-layer virus blocking, decompressing archives and blocking file types, the antivirus engine in the Barracuda Web Filter protects your network from aggressive viruses.

  • Detects & Blocks Spyware Activity

    The Barracuda Web Filter detects installed spyware trying to access the Internet. Upon discovery, it blocks the spyware activity and notifies the administrator.

Content Filtering

  • URL by Category

    Administrators can create policies that control user access to websites using 95 content categories including pornography, violence, hacking, sports, news, dating, shopping, chat and others.

  • URL by Domain or Pattern

    Content filtering policies can be customized to restrict specific websites or look for specific patterns in web addresses. Administrators can specify URL patterns to block sites using the powerful UNIX regular expression (regexp) syntax.

  • Image/Multimedia Safe Search

    The Barracuda Web Filter's image/multimedia safe search feature prevents search engines such as Google, Yahoo and MSN from displaying objectionable thumbnail images in search results.

  • File Type Blocking

    Administrators can create policies that control downloading web files based on their MIME types. For example, to block downloads of executables, you can block MIME type application/octet-stream.

  • SSL Inspection

    Control online content delivered in the classroom with granular control of domains that are normally hidden by SSL. This includes content found in social media platforms, web-based email, and search engines. Administrators can specify domains and URL categories for which SSL-encrypted traffic will be decrypted and scanned for malware and policy. Not only can organizations restrict entire platforms, it's now possible to enforce granular access for secure websites (e.g., YouTube for Schools).

  • Youtube For Schools

    YouTube for Schools is an invaluable resource for educators, serving as a portal to a wide array of high quality educational videos. The Barracuda Web Filter make it easy and safe to use this resource, by automatically redirecting all YouTube requests to the YouTube for Schools portal.

Remote Filtering

The Barracuda Web Filter provides the Barracuda Web Security Agent (WSA), a downloadable client that can be installed on remote, off-network laptops or desktops. With the WSA installed, the web traffic from your devices will be transparently filtered through a Barracuda Web Filter Appliance to ensure that your organization's web browsing policies are extended to the remote users. The tamper-proof and centrally managed Barracuda WSA enables organizations to implement a consistent web security policy across localized and distributed workforces while keeping the solution easy to deploy and manage. The Barracuda WSA supports both Windows and Mac OS X devices.

Flexible Policies

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.

Warning Policies

The Barracuda Web Filter lets administrators create web access warning policies that display a "block" page to users, but lets users proceed after the warning.

Network IP Address Groups

Administrators can define policies that only apply to certain network IP address ranges or subnets.

Local Users and Groups

For locations that don't use directory servers, or wish to define policies for users and groups not managed by the directory server, the Barracuda Web Filter lets administrators create local users and groups.

Time-based Exceptions

You can define policy exceptions for content filtering and application blocking based on time. For example, you can set a default policy to block access to sports sites, but allow access to sports sites during non-working hours.

Centralized Management

Administrators can easily manage several Barracuda Web Filters through the Barracuda Control Center web portal. The Barracuda Control Center lets administrators monitor and configure multiple Barracuda Web Filter appliances at the same time from one console using the same tabbed pages displayed in each appliance's UI.

Web Security Agents

Windows and Mac compatible agents are available to protect and enforce web policies on off-network computers. There are no license fees for Barracuda Web Security Agents.

Spyware Removal

The Barracuda Web Filter comes with a spyware removal tool to disinfect computers that connect to the network carrying spyware.

Web Policy Enforcement

Create granular policies to manage web access by global users, groups and individuals based on 95 content categories, time factors, applications, bandwidth, media and more.
