By adding web filter capabilities only available for dedicated web filter products, the award-winning Barracuda CloudGen Firewall F-Series provides the most powerful tools for administrators to ensure policy compliance and reliable access to web resources.

Enforcing Web Access Policy

Any security policy’s true value is in its tools’ ability to enforce its usage. Now consider that most web access policies are complicated with a level of granularity that creates a challenge for traditional web filtering tools based solely on URL categories. Barracuda CloudGen Firewall combines web filtering with an Application Control module to provide powerful and highly granular settings that match any possible security policy requirement. Access rules based on user identity or group membership, machine health status, time of day, network location, or even individual web application features are available in one firewall rule-set configuration. SSL interception allows transparent decryption and re-encryption of HTTPS traffic for local inspection. Detection and analysis of traffic directed through web anonymizers negates the possibility of evading policy enforcement.

Securing Against Web Threats

Now that the Web is the primary infection vector, securing against web-borne threats is crucial functionality of any web filtering network appliance. Thanks to its cloud-based architecture, the Barracuda URL database can be used to effectively block access to known malicious sites as they appear. All content downloaded from the Web is also subject to extensive antimalware scanning – first by a local antivirus engine, and then by Advanced Threat Detection (ATD) emulation service running in Barracuda’s secure cloud-hosted sandbox environment. Technology partnerships with leading antivirus and ATD vendors ensures state-of-art detection rates and security for users protected by Barracuda CloudGen Firewalls.

Enhancing the Web Experience

Web security entails more than blocking. In today’s SaaS world, it is also extremely important to ensure seamless use of business-related applications and websites, regardless of the remaining traffic passing the firewall. Barracuda CloudGen Firewall F-Series appliance can enforce bandwidth priorities or limitations to selected web categories or applications, moving bulk traffic to the background. It is even possible to offload some traffic to a different Internet provider while still maintaining priority enforcements. Accessing internal web applications like SharePoint or Outlook Web App from remote branch offices will gain additional an boost when passing over the optimized VPN tunnel, providing data compression and deduplication.
