Malware is pervasive and persistent, and unfortunately, usually finds access to the
computers inside your network. Users increasingly work with customers and
partners to collaborate on projects and increase productivity. This increased
collaboration poses challenges for information security professionals to
determine how to prevent malware infections on internal systems from
accidentally infecting key partners, and therefore adversely affecting their
reputation.

The IronPort Web Security appliance provides the outbound malware scanning
feature which allows you to stop malware that is already active on computers
inside the network from escaping the network and affecting customers and
partners.
