Disclaimer
When configuring a User Identity authentication security policy, there is an option to enable a disclaimer. The disclaimer is a replacement message that when enabled, web traffic matching this policy will be presented with the disclaimer that the user must choose to agree or decline.
The default disclaimer contains a warning that any content the user is about to access is the responsibility of the user and not the company or owner of the network. It is presented in Figure 115. You can customize the text and the appearance as required.
