Email threat prevention (ETP) is a security prevention technique that helps minimize the risks associated with a data breach by adding an additional layer of protection to an existing secure email gateway. Today, email is vulnerable to cyber-attacks and ETP is designed to identify and stop email-borne attacks including phishing, ransomware and other exploitable content that is sent in an email body or downloaded as an email attachment.
Cloud Email Protection
Many ETP solutions support on-premises mail servers or is hosted in the cloud to detect and automatically stop an attack before it enters the work environment. Typically cloud email threat prevention analyzes email attachments and URLs against known threats and uses contextual intelligence or data sanitization technologies to scan email, prioritize alerts, remove malicious elements or and block the threats.
ETP solutions (on-premises or cloud-based) are offered by a number of vendors including FireEye, ProofPoint, Symantec, OPSWAT, Check Point and other vendors. Also, specific email and NextGen firewall or application firewall providers may also offer email threat prevention as part of an overall security solution.
