How to Create an Explicit Web Filter Policy

  • Last updated on

The Barracuda SecureEdge Manager allows administrators to configure an explicit Web Filter policy. Explicit Web Filter policies take precedence over predefined security policies. An explicit Web Filter rule blocks or allows URLs from specified sources. In addition, you can now either alert or warn users against suspicious traffic.

The following actions are available for the Explicit Web Filter policy :

  • Allow – The user can access the website.

  • Block – The user is blocked from viewing the website.

  • Alert – The user is allowed to access websites in this category, but the action is silently logged.

  • Warn – The user is redirected to a warning page and must click Continue to access the requested website. Note that Continue will implicitly cause a security inspection.

The Warn action does not work with any non-SSL inspectable domains.

Before You Begin

  • If you want to use the users or groups from user directories (such as Microsoft Entra ID, LDAP, Google Workspace, Okta, and Barracuda Cloud Control) for Web Filter policies, you must first connect your SecureEdge Identity Management in order to synchronize users and groups. For more information, see Identity Management. 

  • If you want to select users or groups from user directories such as BCC-linked Microsoft Entra ID or the BCC-linked LDAP directory in Web Filter policies, you must first connect your directory with Barracuda Cloud Control in order to synchronize users and groups. For more information, see LDAP Active Directory and Microsoft Entra ID and How to Connect Microsoft Entra ID with Barracuda Cloud Control.

Reporting

You can create reports and notifications using Azure Log Analytics Workspace. Your Barracuda SecureEdge service must be connected to Azure Log Analytics Workspace via Azure Monitor Agent. The Azure Monitor Agent is used to stream logs to a Microsoft Log Analytics workspace. Azure Monitor Agent is supported on SecureEdge appliances such as Sites and Private Edge Services.
