This antivirus for Exchange 2013 uses the ScanMail Suite for superior protection for your Microsoft Exchange servers.

Most, if not all, targeted attacks start with phishing emails so your mail server’s security is more important today than ever before.

Unfortunately, most mail server security software rely on pattern file updates which don’t detect every type of malware, plus don’t have specific protections to detect malicious links, URLs, or document exploits used for attacks or advanced and persistent threats.

ScanMail Suite for Microsoft Exchange stops these attacks and phishing by using document exploit detection, enhanced web reputation and sandboxing for defense which you won’t find with other security solutions.

It also blocks traditional malware with email, file and web technology plus correlated global threat intelligence from Trend Micro’s Smart Protection Network cloud-based security.
