Required Action by Connection Method prior to January 29, 2026

• IPsec: Switch to your secondary tunnel prior to the maintenance window, for the duration of the maintenance.
• WSS Agent, Symantec Enterprise Agent: Update any firewall rules regulating connectivity with Cloud SWG to allow traffic to pass to/from the IP networks listed above. Failure to make these changes could prevent users from connecting to Cloud SWG, or authenticating against the service using the Auth Connector (where applicable) after the maintenance. During the maintenance, agent traffic will be automatically redirected by the service to the nearest site.
• Explicit proxy and proxy forwarding: Customers directing traffic to proxy.threatpulse.net will be automatically redirected by the service to the nearest alternate site during the maintenance window.
