Using a soft blocking policy
We all know that although web filtering is required, being too restrictive may cause resentment. It may also lead to people actually being stopped from doing productive work when some certain legitimate sites are blocked.
With soft-blocking you can advise a user that it is against the organization’s policy to visit the site, and leave it up to the user to decide whether they really need to access this site or not. This allows you to empower your users rather than stifle them.
NOTE
To apply “soft-blocking” policies, use the Block, Warn, Allow or Monitor element in configured policies. Instead of “Block” use the “Warn” option.
