E10. Who needs ZyXEL Content Filtering? Is ZyXEL Content Filtering for small companies
or for large corporations?
All businesses can benefit from using the ZyXEL Content Filtering solution
ZyXEL Content Filtering helps organizations manage, monitor, and report on users’ Internet activity
regardless of their location within the organization. Almost any organization — business, government, or
school — can benefit from BlueCoat’s centrally managed, web-based filtering service. Consider the
following:
- 30 to 40% of Internet surfing during work hours is not business related.
- In some companies as much as 70% of bandwidth is consumed by non-productive pursuits.
- 68% of all Internet porn traffic occurs during the 9 to 5 workday.
- 53% of teens have encountered offensive Web sites that include pornography, hate, or violence. Of these,
91% unintentionally found the offensive sites while searching the Web.
ZyXEL Content Filtering is helpful to improve productivity, minimize legal liability, and conserve costly
Internet bandwidth within the organization. BlueCoat provides the most complete and accurate Internet
filtering solution of any Internet management provider and enables companies to better manage, secure
and protect their Internet investment.
