Dear Cisco Customer,

Cisco is issuing this product bulletin to inform customers of a current limitation affecting URL categorization in the Cisco Secure Web Appliance (SWA).

Executive Summary

Cisco has identified a limitation documented as CSCws05684 that may impact certain deployments of Cisco Secure Web Appliance (SWA). This bulletin outlines the scope, potential impact, and Cisco’s recommended actions.

Products Affected

     Product: Cisco Secure Web Appliance (SWA)

     Software Version(s): All versions

     Deployment: [Physical / Virtual / Cloud]

Problem Description

Due to a current limitation under specific conditions, Cisco Secure Web Appliance (SWA) may experience delays in receiving URL categorization updates from Cisco Talos Intelligence, or certain URLs may remain uncategorized, or some URLs might lose their current categorization. As a result, filtering and policy enforcement based on URL categories within SWA may be inconsistent for the affected URLs. This issue affects multiple URLs and is not limited to particular domains or categories

Customer Impact

     Impact Level: Medium

     Potential Impact: This discrepancy can lead to inconsistent filtering and policy enforcement on the SWA for those URLs,

Recommended Action

Cisco recommends one of the following actions, as applicable:

Apply the documented workaround:

     Manually add the affected URLs to a custom URL category or allow/block in the SWA policy to ensure appropriate filtering until the fixed release is available.

     Monitor and review URL category updates regularly to identify any URLs that were previously categorized but have become uncategorized. Such URLs will require manual addition to custom categories to maintain consistent filtering and policy enforcement. This proactive review helps ensure that policy goals are met despite changes in URL categorization sets.

     Upgrade to a fixed release when available

Resolution Status

     Cisco Bug ID: CSCws05684

     Fix Status:

    Fix available in: TBD

    Fix planned for: TBD
