Unlike HTTP, HTTPS connections are protected by SSL. To filter HTTPS websites, the web filter shall have the ability to parse SSL handshake packages.
WFilter, both the enterprise and free editions, all can support blocking of HTTPS domains.
In this post, I will demonstrator you how to block https sites with WFilter Free.
1. Enable Websites Black List
As in the figure, enable a website black list, and check “enable for https websites”. Both http and https websites in the black list will be blocked.
2. Sites being blocked.
HTTP sites being blocked, a denial page will appear.
HTTPS sites being blocked, because it’s impossible to inject a denial page into a ssl connection, WFilter will simple kill the https connection.
