Cisco Secure Client and Captive Portal Detection

The Cisco Secure Client Umbrella Roaming Security module uses multiple techniques to detect captive portals or hotspots. Allow these domains on your firewall for the most accurate captive portal detection:

  • connecttest.cisco.io
  • www․msftconnecttest․com

Note: The connecttest.cisco.io and www․msftconnecttest․com domains have dynamic IP addresses.
