Product Knowledge Requirements

Configuring CWS to allow access only to a corporate Google email account
This procedure is performed in three stages in the ScanCenter admin portal.
A web filtering policy is defined that blocks access to all web-based email
accounts, with the exception of Google
’s Gmail accounts.
HTTPS inspection is defined for web-based email applications.
A Custom Header is defined to tell Google to allow access only to the corporate

Configuration Steps
Blocking web-based email access
1. Log in to your ScanCenter account and navigate to the Web Filtering tab.
2. Click the Management > Filters menu, and then click Create Filter.
3. Create a new filter that will block all access to web-based email. This can be done
in a number of methods, including a combination of methods in a single filter:
a. On the Categories page, select Web-based Email.
b. On the Applications page, select Webmail.
c. On the Domains page, create a list of any other required web-based email
hosts that may not be covered by the above two steps.
Note: If a combination of methods are used in a single filter, any of them could
trigger a match for that filter (OR operator).

4. Save your filter with a meaningful name.
