Installing the Certificate Authority on BYOD devices

Certificate Authorities and HTTPS Interception

This Smoothwall web filter can be configured to use HTTPS Interception. For this to work as smoothly as possible, your device may require an additional certificate authority to avoid problems with HTTPS sites, in particular those with HSTS or HTTPS certificate pinning.

The Certificate Authority will be available from the IT team
