Overview of Trellix Email Security
Trellix Email Security is a comprehensive solution designed to protect organizations from the myriad of threats associated with email communications, which remain a critical and vulnerable vector for cyberattacks.
Key Objectives
Trellix Email Security aims to identify, isolate, and prevent advanced email threats, including malware, phishing, impersonation, and ransomware attacks. It ensures real-time protection against both inbound and outbound email threats, safeguarding the integrity of an organization’s email infrastructure.
Key Features and Functionality
Advanced Threat Detection
- Trellix Email Security employs advanced technologies such as the Multi-Vector Virtual Execution (MVX) engine, which analyzes attachments and URLs across multiple operating systems, applications, and web browsers to detect and block threats, including those hidden in password-protected files, encrypted attachments, and URLs.
Real-Time Threat Intelligence
- The solution leverages real-time threat intelligence from the Trellix Dynamic Threat Intelligence (DTI) Cloud, enabling it to adapt to the evolving threat landscape and prioritize alerts based on contextual insights and known threat actors.
Comprehensive Protection
- It offers protection against a wide range of threats, including credential phishing, spoofing, zero-day attacks, and multistage ransomware attacks that involve callbacks to command-and-control servers. The solution also detects and prevents social engineering attacks such as spear-phishing and impersonation.
Integration and Compatibility
- Trellix Email Security seamlessly integrates with cloud-based email services like Microsoft 365 and Google Workspace, as well as on-premises email infrastructure. This integration allows for auto-remediation of weaponized emails post-delivery and supports custom policies and rules.
Data Loss Prevention (DLP)
- The cloud version of Trellix Email Security includes Data Loss Prevention (DLP) capabilities, which monitor and block email-borne data risks such as exfiltration by insiders and accidental data sharing. DLP rules can be customized using pre-built policies and a policy builder, ensuring compliance with major regulatory frameworks.
Machine Learning and Analytics
- The solution utilizes machine learning and analytics through features like MalwareGuard, which assigns a suspiciousness score to binary files, and Advanced URL Defense, which helps in identifying and blocking credential harvesting and spear-phishing attacks with minimal false positives.
Operational Efficiency
- Trellix Email Security provides tools for investigation and response, including real-time alerts, custom rule creation, and reporting capabilities. It also supports metadata streaming to third-party SIEM solutions and offers advanced debugging options.
Cross-Domain Threat Intelligence
- By integrating with the broader Trellix Extended Detection and Response (XDR) ecosystem, the solution enables cross-domain threat intelligence sharing, enhancing overall security by correlating threats across different security layers.
Deployment Options
- Trellix Email Security is available in both on-premises and cloud deployments. The cloud version offers carrier-grade resilience with 99.995% availability and can be deployed in inline, hygiene (ASAV), or out-of-band modes.
In summary, Trellix Email Security is a robust and adaptive solution that combines advanced threat protection, real-time intelligence, and comprehensive integration capabilities to safeguard organizations against the full spectrum of email-based threats.
