Port and FQDN Requirements

Configure your firewall exceptions to allow ports and FQDNs required by Zero Trust Secure Access services.

Zero Trust Secure Access requires network access to communicate with your corporate applications, third-party applications, and internet gateways. Locate your region for specific FQDN requirements.

In addition to the FQDNs, Zero Trust Secure Access Private Access customers need to open specific ports for the Private Access Connector.
