FEATURE DESCRIPTIONS BENEFITS
Malicious
email content
Degradation
of services
Many types of file attachments,
such as executable programs and
documents with embedded macros,
can harbor viruses. Messages
with HTML script files,
HTML links, Java applets, or
ActiveX controls can also perform
harmful actions.
Non-business-related email traffic
has become a problem in
many organizations. Spam messages
consume network bandwidth
and affect employee
productivity. Some employees
use company messaging systems
to send personal messages,
transfer large multimedia files, or
conduct personal business during
working hours.
IMSVA allows you to configure
the characteristics of
messages that you want to
stop at the SMTP gateway,
thus reducing the chances of
a DoS attack.
IMSVA allows you to configure
the types of messages
that are allowed to pass
through the SMTP gateway.
Most companies have acceptable
usage policies for their
messaging system—IMSVA
provides tools to enforce and
ensure compliance with existing
policies.
