Blocking access to selected websites

Websites can be blocked for a workstation with an installed nVision Agent by means of Agent profiles. By default, all websites can be accessed. To enable blocking, toggle on the integration with TCP/IP stack in the Compatibility and performance tab. To learn how to do this, see the chapter I cannot block websites.

The following protocols are supported at the moment: HTTP, HTTPS, SMTP:25, SMTP:587, SMTP via SSL, POP3 via SSL and POP3:110. The following protocols are not supported at the moment: IMAP, MAPI.

In the nVision options, you can configure the text of the notification to be shown to users when they visit a blocked website.

Excluding domains from blocking rules in the Agent profile

To exclude domains for all the devices used, you must properly configure the Agent profile.

1.	Navigate to the Tools and options tab, and then to the Manage Agent profiles menu.

2.	Select the Agent profile to be edited or create a new one that will suit your needs.

3.	In the Edit window, navigate to the Compatibility tab, and then to the Excluded domains tab.

4.	Add a domain to be blocked and confirm with OK.

Time window

It is possible to set the time window (hours and days) when the given website will be blocked. For example, you can block access on business days during working hours. Thus, outside of the time window devoted to work, the user will be able to access the blocked website.
