Malicious sites found by the security alliance will be immediately added to our URL library to block. This option can be turned on in the page access rules of "Page filtering".

two。 Use the defense function to protect

The address library in web page filtering can filter out most malicious websites, but it is inevitable that there are malicious websites that are not included in the URL library.
