Browser protection
Can users run the browser protection service for Internet Explorer and Firefox on the same
computer?
Yes. The browser protection service for Internet Explorer and Firefox are compatible on the
same computer. Users can install protection for both browsers. (If both browsers are present on
a computer when browser protection is installed, protection for both browsers is installed
automatically.)
Is it safe to use the browser protection service as my only source of security against web-based
threats?
No. The service tests a variety of threats, and constantly adds new threats to its testing criteria,
but it cannot test for all threats. Users should continue to employ traditional security defenses,
such as the virus, spyware, and firewall protection services in Enforced Client, for a multi-tiered
defense.
Email
Is my computer protected from email viruses?
Yes. The virus and spyware protection service (on desktop client computers) features an
on-access scanner that scans email messages and attachments as they are accessed or opened. It
also cleans infected email messages before they are delivered to the user’s Inbox when the
Scan
email option
on the Advanced Settings tab is enabled (see Enable optional protection on page 97).
For enhanced email security, SonicWALL offers Enforced Client Advanced. With this solution,
you have the power of an email security service that routes email messages through SonicWALL
servers and scans them for spam, viruses and other threats before they are received by client
computers. Detections are blocked or quarantined. An email server security application can also
be implemented to protect Microsoft Exchange and Lotus Domino email servers against viruses.
Can I scan email messages on demand?
Yes. In your Microsoft Outlook Inbox, select one or more messages, then from the Tools menu,
select
Scan for Threats.
After installing the email security service, why am I not receiving email or seeing any charts on
the email service’s portal?
To determine and resolve the problem, visit the email security service’s portal (see Using the
portal on page 134) and run the System Tests listed on the home page. Refer to the
Administration Guide for more information on the tests (see Getting more information on
page 143).
General
Can I use a non-Microsoft browser, such as Mozilla Firefox or Opera?
Yes. The client computer must use Microsoft Internet Explorer 5.5 SP2 or later to install the
client software. However, once the client software is installed, the default Internet browser can
be used for other purposes. You can view the SecurityCenter using Internet Explorer or Firefox.
