    I think you may have enabled HTTPS-scanning. If you enable it, the original certificate will be replaced by a certificate on the UTM (if you didn't purchase any, than its a self-signed certificate).
    You will have to have this certificate trusted to the clients to stop getting certificate warnings.

    Managing several Sophos UTMs and Sophos XGs both at work and at some home locations, dedicated to continuously improve IT-security and feeling well helping others with their IT-security challenges.

    Sometimes I post some useful tips on my blog, see blog.pijnappels.eu/category/sophos/ for Sophos related posts.
