Tip  To guarantee availability, Forcepoint Web Security Cloud uses global load balancing to direct traffic across multiple geographic locations. In the event of localized connectivity issues, data center load balancing automatically routes requests to the next closest location. To make the most of the resilience offered by this infrastructure, users must be allowed to connect to the entire cloud network. For details of the IP address ranges in use by cloud service data centers, see the article Cloud service IP addresses and port numbers in the Forcepoint Knowledge Base.

Note  Remote users should use the alternate PAC file addresses (using port 80 or 443) if requesting access from networks that may have port 8081, 8082, or 8087 locked down.
