More than 90% of targeted cyber attacks begin with spear phishing emails, underscoring the urgent requirement for enhanced mail server security. Unfortunately, many current security measures, such as the basic protections found in Microsoft® Exchange™ 2013 and 2016, rely on outdated pattern file updates that mainly detect traditional malware. These approaches often fall short in their ability to identify malicious URLs or document exploits, which are common in sophisticated attacks and advanced persistent threats (APTs). On the other hand, ScanMail™ Suite for Microsoft® Exchange™ takes a proactive stance against highly targeted email threats and spear phishing by utilizing advanced document exploit detection, a superior web reputation system, and sandboxing, all integral to a customized APT defense strategy that competitors do not offer.
