Viewing and customizing user alerts for HTTPS Inspection

When you turn on HTTPS Inspection, Web Security blocks any site with a certificate error and displays an error message. You can use the default alert, or you can customize the alert message.
When you customize an alert, you may personalize the message with your company logo or add a link to your company's acceptable use policy. If this content is not secure, however, users must respond to a warning before they can view your custom error message. The warning asks if the user wants to view both secure and non-secure data. If the user chooses yes, they see the full user alert, with both secure and non-secure content . If they choose no, they see only the secure parts of the alert.
