Cisco Secure Access Help Manage Certificates Add Customer CA Signed Root Certificate

Last updated: Aug 07, 2025

Add Customer CA Signed Root Certificate

You can use a certificate signed by your Certificate Authority (CA) to enable secure connections between user devices in your organization and Cisco Secure Access.

A root certificate is required for Block Pages and Internet Decryption.

  • For Block Pages, if you visit a blocked domain through HTTPS, a certificate must be installed so that Secure Access presents a block page rather than a browser error. For more information, see Manage Notification Pages.
  • For HTTPS decryption and inspection, if a domain is proxied, install a certificate so that Secure Access can decrypt HTTPS traffic without the browser presenting an error. For more information, see Manage Traffic Decryption.

You can use either the Cisco Secure Access root certificate or your own CA-signed certificate. To use your own CA-signed certificate, upload a certificate signed by your CA to Secure Access.
