1. How can I block the QUIC protocol?
You can block the QUIC Protocol (UDP port 443) within the Web Filter application itself. Go to Apps > Web Filter > Advanced to enable QUIC:
2. What is the difference between Web Filter & Web Monitor?
Web Filter can filter your Web traffic and provide you the ability to block websites by URL, category or user. It also logs all web traffic to the reports for Web Filter. Web Monitor only has the logging ability of Web Monitor: it will not block any traffic.
**Note: It is advised that you do not run both Web Filter and Web Monitor at the same time.
3.Why block both MIME type and file types in Web Filter?
In an ideal world, both pieces of information would always be present for every web request. However, some sites use incorrect content types or extensions. The behavior of operating systems (Windows vs. Mac) is also different when given only file extension or content type. To be safe, both lists should be used.
4.How can I block all Websites except certain ones?
In Web Filter, simply block all categories (including "Uncategorized"). Then add whatever sites you'd like to pass in Web Filter > Pass Sites (more instructions here). Please be aware that the complex nature of the web and the fact that many applications communicate over HTTP can make this approach difficult.
5.Why is a site not properly displayed after entering it into Pass Sites?
It's common for a web site to display links, banners and content from other web sites as part of their web pages. There are two easy methods to re-integrate the content while maintaining your access controls. A good example is Facebook - when you go to 'facebook.com', much of the site is loaded from 'fbcdn.net', which also must be entered in Web Filter > Pass Sites for it to display properly. To fix these problems, just look in the Event Log for domains that are still being blocked when you load the site. If nothing is showing as blocked in the Web Filter logs you will want to check other applications, like Application Control, to see if you have the site / service in question blocked there.
6.How long does Web Filter cache category information for sites?
Several days. Web Filter flushes non-frequently used cache. Any website that you visit daily will not be cleared from cache.
7.How do Web Filter real-time updates work?
When a client first visits a site, Web Filter does a live lookup against Webroot's BrightCloud® database and assigns the traffic to the appropriate category. The category information is also written to a local cache so it doesn't have to be checked the next time a user visits that site.
8.Can I use both Web Filter and Web Monitor at the same time?
We do not allow installing Web Monitor if Web Filter is already installed. Running both of these together has been known to cause issues and is never recommended.
9.How can I submit a mis-categorized or uncategorized site?
If you are running the paid Web Filter app you can do this from the application itself in Web Filter > Site Lookup tab. Enter in the URL of the website in question then click on Search. If you feel this categorization is incorrect, you can select the Suggest a Different Category option, select the most appropriate category in the drop-down menu, then select Submit.
You can also use this tool on the BrightCloud® website: https://brightcloud.com/tools/url-ip-lookup.php
10.How should I handle Web Filter false positives?
To allow users to access to a website that is currently blocked, add the site to your Pass Sites list.
