Trend Micro Deep Discovery Email Inspector uses advanced detection techniques to identify and block spear phishing emails that are often used to deliver advanced malware and ransomware to unsuspecting employees. By working in tandem with your existing secure email gateway or replacing it completely, Email Inspector can detect and block purpose-built spear phishing emails along with advanced threats and ransomware. Email Inspector can be deployed in MTA (blocking), BCC mode (monitor only), or SPAN/ TAP mode.
