BES stands for BlackBerry Enterprise Server. It
gives your BlackBerry access to a corporate
intranet. The intranet is the private, internal,

internet that is cut off from the rest of the world.
Many intranets allow you to communicate with the
Internet as well, but with added layers of security.

email, as well as retrieve webpages and use third-
party applications (like WICKSoft Mobile

nice and secure location.
