Both our Exchange and SAN networks are protected by the latest firewall technology, which prevents unwarranted intrusion and ensures that only authorized requests are processed. In addition, the ports required for providing access to the services and managing servers are the only ports open on the firewalls. All incoming mail traffic is checked by industry‐leading Anti‐spam and Anti‐virus applications which use perimeter scanning technologies that stop spam and viruses before they ever reach the Exchange environment.
