Trend Micro
More than 90 percent of targeted attacks begin with a spear phishing email, which means your mail server security is more important than ever. Unfortunately, most mail server security solutions, including the limited set of built-in protections in Microsoft® Exchange™ 2013 and 2016, rely on pattern file updates, which only detect traditional malware. They don’t include specific protections to detect malicious URLs or document exploits commonly used in targeted attacks or advanced persistent threats (APTs). ScanMail™ Suite for Microsoft® Exchange™ stops highly targeted email attacks and spear phishing by using document exploit detection, enhanced web reputation, and sandboxing as part of a custom APT defense, protection you don’t get with other solutions. In addition, only ScanMail blocks traditional malware with email, file, and web reputation technology and correlated global threat intelligence from Trend Micro™ Smart Protection Network™ cloud-based security. -
