Mail security has become an increasingly more important issue these
days for all businesses. Having a quality mail filter will prevent your
systems from becoming infected with viruses, spyware, malware, spam, and
eliminate critical down-time.
For tight enterprise security, Antivirus and Antispam is tackled at the perimeter of your private network so that malware does not propagate within your network servers and workstations. Kingsoft offers the best solution offered by Symantec for this scenario. Antispam engine is rendered on SMTP box like MS Exchange Server and Antivirus is deployed as separate box which downloads all new definitions and other client machines download their definitions from this managed server, reducing network traffic.
We use Symantec Mail Security for Exchange. Some of the key feature of this solution are:
•Defend against new and known viruses and security risks for superior
virus protection that is backed by Symantec Security Response, the
world's leading antivirus and Internet security research organization.
.
•Enable best-of-breed spam prevention by simply activating the optional
subscription when purchasing a license key - no additional software to
install.
•Filter inappropriate content within most file formats and block files
based on true file type (not just file extension) while preventing
inappropriate communications.
