Following on from our recent guide on how to manage non work related internet usage during worktime without blocking internet access. Faced with this drain on productivity, organizations do have options. There are ways to block specific sites. Organisations can block specific domains or IP Address at the network or at the individual browser level. However it’s important to take into account that an overly strict internet blocking policy can have a demoralising effect and make the company a less attractive place to work.
Implementing a content filter is now crucial for businesses. Social media websites can be a drain on productivity. Some employees may spend hours of each day browsing and updating Facebook, this is time spent not working. Blocking social media or Facebook is too extreme a measure; however every company must protect itself from the potential liability of employees browsing to undesirable material while at work, as well as blocking the malware that arrives through illegal, malware laden and inappropriate sites.

How to Block Facebook Chat Without Blocking Facebook Access
To block Facebook chat at work, open your WebTitan Cloud administration panel and navigate to “Filtering URL keywords.”
You need to add in two blacklisted keywords. Enter in the first keyword:
Set filter options to ‘find keyword in entire URL’
The second keyword that must be blocked is:ajax/mercury/send_messages.php
As before, set filter options to ‘find keyword in entire URL. These two files are used by Facebook chat and if the files are blocked, the Facebook chat will not function, although the Facebook website will still be accessible.
In order for URL keywords to work correctly it is necessary to have the SSL certificate pushed out to the browsers.
Further information on how to do this via GPO or manually can be found in the help section on the WebTitan website.
