Introduction to Trend Micro Email Security

Email impersonation is a preferred attack method used by hackers, alongside ransomware and phishing attacks aimed at stealing money and sensitive information. Clearly, email represents an open gateway into enterprises. Through non-technical attack techniques (social engineering(*), even the most security-aware users—such as employees or customers—can be deceived into clicking malicious links, opening ransomware-laden attachments, or altering payment account details, thereby impacting the business.

Organizations need smarter email security to address all aspects of email-borne threats, as well as security that continuously learns and evolves to keep pace with the latest threats. Security solutions must be easy to manage and capable of sharing intelligence with other security layers to immediately protect enterprises against emerging and unknown threats. Trend Micro Email Security, powered by XGen technology, leverages a multi-generational security approach to help organizations protect, detect, and respond instantly to email attacks.

(*): Social Engineering is a common term in the field of information security, describing a type of attack that manipulates human behavior rather than exploiting technical vulnerabilities in machines or devices. Through this approach, attackers can achieve their objectives—such as gaining system access or obtaining sensitive information—without relying on complex technical attack methods.

SMARTER SECURITY AGAINST EMAIL-BASED THREATS

Trend Micro Email Security addresses the entire email threat lifecycle—from protection and detection to response. Trend Micro protects organizations against inbound email threats such as ransomware, impersonation, phishing, and targeted attacks, while also providing tools to detect internal threats spreading within the organization.

Trend Micro rapidly shares threat intelligence across other security layers and enables organizations to search their email and collaboration systems for existing malware or compliance violations.

PROTECTION AGAINST IMPERSONATION / PHISHING ATTACKS

Trend Micro provides comprehensive protection against impersonation and phishing threats. XGen security combines multi-generational defense techniques to accurately detect the broadest range of email attacks. Advanced techniques are then progressively applied for deeper analysis, minimizing delays in email security inspection for inbound and outbound messages.

BUSINESS EMAIL COMPROMISE (BEC) / FRAUD PROTECTION

Trend Micro combats Business Email Compromise (BEC) attacks using artificial intelligence, including expert systems and machine learning, to inspect email headers, content, senders, and more. Stricter inspection criteria can be applied to high-profile or critical users and executives within the organization.

Email impersonation of executives or key personnel is prevented using Trend Micro’s unique Writing Style DNA technology. This technology analyzes writing patterns and compares them using machine learning to determine whether an email truly originates from the claimed sender.

RANSOMWARE & OTHER MALWARE PROTECTION

Trend Micro Email Security is the only email security solution that implements pre-execution machine learning to accurately detect previously unknown malware without impacting email delivery time.

Advanced sandbox behavior analysis further identifies unknown threats in email attachments, including Office documents (with macros), PDFs, archives, executables, scripts, and multimedia files.

MALICIOUS URL FILTERING

• URL analysis during delivery and at the time of user click
• Dynamic sandbox analysis of shortened URLs and redirected URLs
• Analysis of URLs embedded in attachments and scripts

EMAIL SECURITY FUNNEL MODEL

DETECTING INTERNAL ENTERPRISE ATTACKS

In multi-stage attacks, hackers may first compromise a device, steal employee or user credentials, and then use that account to send phishing or impersonation emails to other employees or users within the organization. It is critical to detect and stop attacks that are already spreading internally.

Trend Micro provides advanced threat protection and internal Business Email Compromise (BEC) and phishing/impersonation defense for Microsoft® Office 365®, Microsoft® Exchange, Gmail, and IBM® Domino. Since collaboration services can also be used to propagate internal attacks, Trend Micro additionally protects Microsoft® OneDrive®, Microsoft® SharePoint®, Box, Google Drive, and Dropbox.

OPTIMIZED FOR ENTERPRISE ENVIRONMENTS

Trend Micro offers multiple solutions designed to best fit enterprise environments. Trend Micro provides email gateways in the form of cloud-based services, virtual appliances, and physical appliances, as well as APIs for protecting Microsoft Exchange and IBM Domino, along with the most popular collaboration services such as Box, Dropbox, Google Drive, SharePoint, and OneDrive. Support is also available for Microsoft Office 365 and Google Workspace.
