McAfee Email Gateway

McAfee Email Gateway

Total email protection for enterprises

Next Steps:


McAfee Email Gateway consolidates inbound threat protection, outbound encryption, advanced compliance, data loss prevention, and administration into a single, easy-to-deploy and user-friendly appliance. As a comprehensive email security solution, Email Gateway can stand alone or work in tandem with McAfee SaaS Email Protection & Continuity as an integrated hybrid solution. It eliminates ineffective piecemeal defenses, simplifies multivendor security environments, and reduces operating costs — while significantly strengthening email security.

Email Gateway delivers:

Total inbound protection — Inbound protection goes beyond blocking spam. Email Gateway provides powerful antispam scanning technologies to identify and block incoming spam with over 99% accuracy. It also protects your network from malware, zero-hour threats, phishing, viruses, blended threats, directory harvest, denial of service (DoS), bounceback attacks, and spam surges.

Total outbound protection to keep your data secure — Available at no extra charge are encryption (push, pull, TLS, S/MIME, PGP) and built-in data loss prevention (DLP) capabilities that utilize the same text-matching dictionaries found in McAfee Data Loss Prevention — with the ability to scan over 300 document types. These compliance and DLP capabilities are fully used from the Email Gateway administrative interface or McAfee ePolicy Orchestrator (ePO). Using sophisticated content-scanning technologies, multiple encryption techniques, and granular, policy-based message handling, Email Gateway prevents outbound data loss and keeps sensitive data secure.

Simple, powerful administration from within McAfee ePO — With Email Gateway, administrators can deliver superior email protection and document it with customizable, enterprise-class reporting, exportable report logs, real-time dashboards, and alerts. Email Gateway combines performance, scalability, and stability with a flexible delivery model to ensure maximum ROI.

A virtualized solution — The Email Gateway appliance is also available as a virtual appliance, so you can reap the benefits of virtualization. With lower costs than a physical appliance, a virtual appliance also provides maximum flexibility, including the ability to consolidate solutions on a single server.

Enhanced security powered by McAfee Global Threat Intelligence (GTI) — McAfee GTI is a comprehensive cloud-based threat intelligence service. Integrated into McAfee security products, it works in real time, 24 hours a day, to protect customers against cyberthreats across all vectors — file, web, message, and network. McAfee GTI offers the broadest threat data, most robust data correlation, and most complete product integration in the industry. McAfee’s GTI network allows enabled products to evaluate threats on multiple vectors in real time, leading to faster identification of threats and higher capture rates. Email Gateway uses the message, network, and web reputation service to identify email messages carrying malicious payloads.

Security Connected integration for advanced malware detection — For the most sophisticated and targeted email attacks, integration with McAfee Advanced Threat Defense provides a closed-loop solution capable of eliminating the stealthy and zero-day malware often used to enter organizations through spear phishing. McAfee Advanced Threat Defense combines in-depth static code and dynamic analysis (sandboxing) to analyze the actual behavior of malware. A tight integration between Mcafee Email Gateway and McAfee Advanced Threat Defense enables this analysis to be conducted on suspect files attached to email, blocking those found to be malicious before they ever reach an inbox.

Features & Benefits

Real-time Global Threat Intelligence defends against inbound and outbound malware and spam threats

Get quicker, accurate detection of spam, malware, malicious embedded URLs, zero-hour threats, and other email-borne threats with the network, file, web, and message reputation intelligence from the breadth of McAfee security devices around the globe. Get protected from directory harvest denial of service (Dos) bounceback and spam surges. A dual antivirus solution addresses defense-in-depth compliance requirements, while eliminating licensing costs and management with this built-in functionality. The second antivirus engine may be turned off, or turned on for exhaustive scanning or in optimized mode, where it scans only those that pass through the McAfee antivirus engine.

Integration with Advanced Threat Defense stops sophisticated malware used in spear-phishing attacks

Gain the most in-depth malware detection capabilities available through a tight integration between McAfee Advanced Threat Defense and McAfee Email Gateway. Advanced Threat Defense uses advanced static code and dynamic analysis (sandboxing) to provide the most detailed assessment and data on malware classification. Stealthy malware and zero-day threats are packed or obfuscated to evade detection, and Advanced Threat Defense employs strong unpacking to break through evasive techniques, enabling thorough analysis and accurate classification. These two solutions work together to find sophisticated attacks and freeze them in their tracks, removing malicious email messages without the need for manual intervention by overworked network operators or security analysts.

Use graymail filtering to further reduce unwanted email

Unwanted mail could be legitimate bulk mail that was once solicited by the user, but now no longer wanted (i.e., industry newsletters and notifications), and may represent a significant nuisance to recipients. By using graymail filters, administrators can set graymail policies for individuals or groups, and even permit end users to enable this capability to keep mailboxes clear of graymail.

Keep your emails from prying eyes, while keeping your deployment simple

Eliminate the need to source, manage, or integrate a separate encryption product. Built-in, policy-based email encryption supports a wide user base, and includes a combination of B2B (TLS, S/MIME, OpenPGP) and B2C (push, pull, push and pull) technologies. Enable your recipients to receive and reply to secure email, even if they do not have encryption capabilities in place.

Reduce risk of exfiltration by leveraging extensive built-in compliance templates

Take advantage of flexible policy creation and enforcement, plus enterprise-class logging and real-time dashboard and reporting capabilities, to simplify administration and compliance workloads while lowering costs. Email Gateway includes over 114 compliance templates, the same as those in McAfee Data Loss Prevention (DLP), to support GLBA, HIPAA, SOX, and other compliance mandates.

Keep structured and unstructured data secure

Prevent data loss with the industry’s most extensive on-box email DLP capabilities. Fingerprinting, lexical analysis, and clustering techniques supplement keyword and pattern matching to detect both structured and unstructured data. Policy-based message handling then prevents outbound data loss. These industry-leading email content analysis tools provide the tightest control of sensitive content in any form to aid compliance with many state, national, and international regulations. Keep your data secure by filtering beyond Microsoft and PDF documents and scanning over 300 document types. Email Gateway can also integrate with McAfee DLP Prevent to enhance the solution’s ability to correctly identify sensitive data and assist in its safe handling, minimizing risk.

Gain deployment flexibility for peace of mind

Reap the benefits of an integrated hybrid solution with Email Protection. It eliminate costs of paying for two solutions to cover your email security, eliminate the inefficiencies of a patch-worked hybrid solution, or take a step towards leveraging the benefits of a cloud-based solution. Choose Email Protection to implement an integrated hybrid solution that gives you the best of the Email Gateway appliance with McAfee SaaS Email Protection and Continuity to give you the best of both worlds, all through a single pane of glass management and reporting interface. Block malware and filter spam in the cloud, away from your network, to save bandwidth cost and protect sensitive data with on-premises Email Gateway (virtual appliance, hardware appliance, or blade server) for encryption, flexible policy creation, and data loss prevention.

System Requirements

Deployment flexibility is a hallmark of McAfee Email Gateway. You can deploy it as a virtual machine, hardware appliance (four different appliance sizes), or on a blade server architecture that sits in front of an existing email server.

Virtual Appliance

These are minimum hardware requirements for the virtual appliance. Actual requirements will vary depending on the nature of your environment.

You can use McAfee Email Gateway in a virtual environment with these platforms:

  • VMware ESX 4.1 or later
  • VMware Player

Hardware Appliances

A complete range of enterprise and medium-capacity appliances offers affordable protection and scalability for the most demanding business messaging environments.

Please see the McAfee Email Gateway Appliance Hardware Specifications sheet for additional details about the EG-4000, EG4500, EG5000, and EG5500.
