Cloud SWG: High‑Risk Isolation Service Update September 06, 2026

Broadcom announced a scheduled maintenance window for its Cloud Secure Web Gateway (SWG) High‑Risk Isolation service, set for September 06, 2026.

The 10‑hour maintenance window will run from 02:00 UTC to 12:00 UTC, during which the High‑Risk Isolation service will be temporarily unavailable for all Cloud SWG customers.

Purpose of the Update

Broadcom aims to improve the stability and performance of the isolation environment that protects users from malicious web content. The update includes backend infrastructure enhancements and additional monitoring capabilities.

Impact on Customers

During the maintenance period, any traffic that would normally be routed through the High‑Risk Isolation service will be blocked, resulting in potential access delays or failures for affected web resources.

Customers are advised to plan for this outage by adjusting security policies, informing end‑users, and scheduling critical web activities outside the maintenance window.

• Review and adjust isolation policies in the Cloud SWG console
• Notify end‑users of possible access interruptions
• Schedule critical web‑based tasks before or after the 02:00–12:00 UTC window

Next Steps and Support

Broadcom will provide real‑time status updates on its service status page throughout the maintenance. Support teams remain available to address any issues that arise once the service is restored.

"We are committed to delivering a more resilient isolation service and appreciate our customers' understanding during this essential maintenance," said a Broadcom spokesperson.
