    • ARM64 devices only support the Secure Client with the VPN module, DART, Secure Firewall posture, Network Visibility module, Umbrella module, and ISE posture.
  • macOS 11.x or higher

For more information about the Cisco Secure Client, see Cisco Secure Client (including AnyConnect) Administrator Guide, Release 5.1.

Network Requirements

Secure Access DNS Block Pages

Secure Access and SAML Identity Provider Domains

Note: When using an SSL-VPN, add the IP address of the VPN head-end to the external domains settings. For more information, see Manage Domains.

Transport Layer Security Protocol

Network Access

Host Names

  • The Cisco Secure Client Umbrella Roaming Security module uses hostnames for registration. All machines must have a hostname that is unique within your organization.

Secure Access DNS Resolvers

For more information, see Network Requirements for Secure Access: DNS Resolvers.

Encrypted DNS

External DNS Resolution

HTTP and HTTPS

The Cisco Secure Client Umbrella Roaming Security module uses HTTP (80/TCP) and HTTPS (443/TCP) to communicate with Secure Access for the following uses:

  • Initial registration upon installation
  • Checking for new versions of the Cisco Secure Client Umbrella (Roaming Security) module
  • Reporting the status of Cisco Secure Client Umbrella (Roaming Security) module to Secure Access
  • Checking for new internal domains

Windows Only: If you utilize an HTTP proxy that is configured at the user-level (normally using GPO), make sure the SYSTEM user is also configured to use the proxy. Otherwise, add the following rules to your firewall to ensure the Cisco Secure Client Umbrella (Roaming Security) module can reach Secure Access.

Secure Access DNS – Client Configuration Services

Secure Access DNS – Client Sync Services

Secure Access DNS and Web – Client Certificate Revocation Services

For more information, see Network Requirements for Secure Access: Client Certificate Revocation Services.

Roaming Security DNS Requirements

  • The Cisco Secure Client Umbrella Roaming Security module is not compatible with other DNS serving software. You should not install the Cisco Secure Client Umbrella module on a device that serves DNS requests.
  • Uninstall DNSCrypt before your install the Cisco Secure Client Umbrella (Roaming Security) module. The Cisco Secure Client Umbrella (Roaming Security) module installer automatically detects installations of DNSCrypt and prompts the administrator to uninstall before proceeding with the installation.
  • Install the Cisco Secure Client Umbrella Roaming Security module on the C:\ drive. The Cisco Secure Client Umbrella module does not support secondary or remote drive installations.
  • The Cisco Secure Client Umbrella Roaming Security module only supports dual-stack IPv4/IPv6 for macOS and Windows. Standalone support for IPv6 for both macOs and Windows is not supported.

Internal Domains

The Cisco Secure Client sends all of your DNS lookups directly from your computer to the Secure Access global network resolvers. Thus, to ensure that Cisco Secure Client directs internal DNS requests to your internal DNS servers for resolution, you must add your local domain names to the internal domains list in Secure Access. The Cisco Secure Client's Umbrella module syncs with Secure Access periodically to check for new internal domains. This is a critical part of the setup process. We recommend that you populate the list of internal domains before you deploy the Umbrella (Roaming Security) module. For more information, see Domain Management.
