Client Certification Authentication

  • Last updated on

You can authenticate users of your applications through a trusted certificate, rather than using passwords. Upload one or more trusted certificates from a Certificate Authority (CA) to enable users to access your applications.  When a prospective user of your application connects to your server, their web client electronically presents their certificate for authentication. In return, your server can verify their certificate and, if it is acceptable, grant the user access to your application. 

Uploading a CA certificate to Barracuda WAF-as-a-Service requires a PEM file. Follow the instructions provided by your Certificate Authority to create a PEM file.

To upload a CA certificate:

  1. Navigate to the application you want to associate with the CA certificate. 
  2. In the left navigation panel, go to Client Certification Authentication.

Be sure to:

  • Enable the certificate to authenticate your application.
  • Replace an expired certificate with an updated certificate.
