The Web is an integrated mix of interesting technologies that open the door to numerous security threats. The same things we get excited about happening on the Web are the very same things leaving a gaping hole in enterprise security. The Web is a serious threat to Internet users and corporate networks, and traditional URL filters can't keep up.

Barracuda Networks helps you balance the need to protect sensitive information, enable access to dynamic Web 2.0 functionality, and control bandwidth. With the Barracuda Purewire Web Security Service, there is no equipment to maintain and pricing is easy and predictable. The service integrates multiple layers of advanced threat protection and compliance functionality to provide real-time defenses against a quickly evolving threat landscape.

The Barracuda Purewire Web Security Service combines sophisticated layers of threat protection:

• Anti-virus signatures, updated hourly, to provide a rapid response to new known security threats
• Object-based malware detection using string scanning and advanced heuristic technology to block unknown Web-based viruses and spyware
• AJAX-aware analysis detects malicious Web applications and script-based attacks
• HTTP-focused behavior analysis and intrusion detection identify and block botnet communication, spyware and rogue AV

The Barracuda Purewire Web Security Service offers flexible deployment options to protect users online, no matter where they are or how they access the Web. Deployment options range from simply configuring a Web browser to more advanced directory integration and transparent intercepting proxy configurations. As a cloud-based solution, the Barracuda Purewire Web Security Service is perfect for distributed locations, to centrally control and manage security and acceptable use policies from a single location with consolidated reporting across multiple locations, devices and users.

The service enforces compliance across your organization, with centralized control of Web usage and global visibility of truly real-time, consolidated reporting. Our URL database is enhanced with real-time reputation scoring and content analysis. Several different levels of content filtering happen based on file types, content types and Web response content to provide a layer of data leak prevention to stop sensitive information from leaving your organization via Web traffic. The service also provides application and bandwidth control to manage access to various Web applications, including non-browser based Web applications such as instant messaging, VoIP, P2P file sharing and streaming media applications.

Employees are just as likely to browse the Web from their laptop in a hotel, coffee shop or home as they are in the workplace. Existing Web security solutions require VPNs and bandwidth-hungry backhauling for some partial protection. The Barracuda Web Security Agent eliminates the burdens that current Web security solutions require and takes the performance and functionality of the Barracuda Purewire Web Security Service beyond the corporate perimeter. The Barracuda Web Security Agent enforces Web traffic through the Barracuda Purewire service for policy enforcement and security protection, and is tamper-resistant to prevent user bypass or reconfigure. Enterprises have an option for silent install and support for user- and group-based policies.

What are the key functions of the Barracuda Purewire Web Security Service?

The Barracuda Purewire Web Security Service is a cloud-based secure Web gateway that protects users from malware, phishing, identity theft, and other harmful activity online. Additionally, the service enforces organizational Internet usage policies through content filtering, URL filtering and application blocking. It is centrally managed with real-time consolidated reporting and provides proactive defenses against a quickly evolving threat landscape. Enterprises simply point their Web traffic to the service, and it protects users online regardless of location or physical device, including laptops and mobile devices.

How does the Barracuda Purewire Web Security Service block Web sites?

The Barracuda Purewire Web Security Service includes 67 categories and 7 super-categories of Web sites that are updated regularly. These categories include Web sites known to include spyware, pornography, and other offensive materials. Additionally, the service performs real-time page content analysis and reputation scoring to accurately determine what exactly is happening on the page at that exact moment. This is increasingly important as more and more legitimate Web sites are compromised with malicious content.

Can the Barracuda Purewire Web Security Service block different sites for different users?

Yes, the Barracuda Purewire Web Security Service enables administrators to customize policies for specific users, groups, and IP address ranges in the organization. Administrators also can establish usage thresholds by schedule, bandwidth, requests or browsing time.

Sample uses for these capabilities 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
  
  

The Barracuda Purewire Web Security Service integrates with popular LDAP compatible directory servers to facilitate transparent user authentication.

How do I connect to the service and ensure my users are authenticated?

There are three ways to connect to the Barracuda Purewire Web Security Service:

• Direct to Service: The easiest way to use the Barracuda Purewire Web Security Service is to directly proxy your Web traffic to the cloud-based content filtering and malware protection service. This can be done with browser proxy settings or by transparently forwarding traffic from any network firewall or proxy that supports forwarding to an upstream proxy.
• Adapter: The Barracuda Adapter is an on-premise solution that forwards Web traffic to the Barracuda Purewire Web Security Service, integrates with your directory service for group-based policies, and caches static Web content locally to save bandwidth. The Barracuda Adapter is available as a hardware appliance, a virtual appliance or as a plug-in to your Microsoft ISA Server.
• Web Security Agent: The Barracuda Web Security Agent protects remote and roaming users by enforcing all Web traffic from laptops through the Barracuda Purewire Web Security Service. The Barracuda Web Security Agent is a lightweight, tamper-proof client available for Microsoft Windows laptops and desktops.

Can legitimate Web sites be blocked? How do you handle this?

Yes, policies can be set down to the user level to block specific Web sites. The Barracuda Purewire Web Security Service can be configured to allow password-override for certain employees or groups as needed.

What is spyware?

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.

Should I deploy desktop anti-spyware tools even if I have a Barracuda Purewire Web Security Service?

The Barracuda Purewire Web Security Service is an effective cloud-based gateway solution to act as a primary line of Web threat defense but it is generally beneficial to layer security solutions. This is particularly useful in cases where spyware threats infiltrate through means other than the Web, including via laptops, USB keys, CD-ROMs, or floppy discs.

What happens to laptops that my employees sometimes use to work remotely? How are they protected?

The Barracuda Purewire Web Security Service protects users online no matter where they are accessing the Web, including laptops and mobile devices. The Barracuda Web Security Agent is a tamper-proof client that enforces access through the service to ensure policies are enforced and malicious content is avoided.

Which ports does the Barracuda Purewire Web Security Service filter?

The Barracuda Purewire Web Security Service Filter scans and filters port 80 (Web) for content filtering, spyware blocking, and virus blocking.

How does the administrator interact with the Barracuda Purewire Web Security Service?
