Zyxel Usg 1000 BlueCoat content filter cannot block any HTTPS websites.
I bought BlueCoat content filter subscription and I see my users can open any https websites.
How can I block pornography web sites (most of them https now)?
Could anyone please advice me what i can do?
Best regards,

@yan,

To decrypt HTTPS content, the “SSL Inspection” function is required. However,  the USG1000 does not support SSL Inspection to filter or block the https websites.
The SSL Inspection function was supported on USG110,210,310,1100,1900 which may fulfill your requirement.

BTW, I guess the content filter (if the device is fitted with) is also partly working with https websites because the SSL encryption is being negotiated between client/server after the website is called. Means, the content filter (provided the device holds a valid Content Filter subscription) is checking whether the called URL is listed at the Zyxel Rating Server (black-listed) for unwanted content.
