Bolster your defenses against email attacks

Protect against emerging zero-day attacks with the Capture Advance Threat Protection service. Our cloud-based sandboxing technology scans a broad range of email attachment types to detect advanced threats, analyze them in a multi-engine sandbox, block them prior to a security verdict, and rapidly deploy remediation signatures. Leverage multiple, patented protection techniques to stop spam and email attacks. Check email sender IP reputations, as well as the reputation of content, structure, links, images and attachments. Protect against directory harvest attacks (DHAs) and denial of service (DoS) attacks and ensure sender validation. Uncover new threats and hidden known threats with a Support Vector Machine (SVM) algorithm, adversarial Bayesian filtering, image analysis and gibberish detection. Identify spoofed mail and reduce spam and phishing attacks with powerful Domain-based Message Authentication, Reporting and Conformance (DMARC) email authentication technology. Get reports on sources and senders of email, so you can detect and shut down unauthorized senders falsifying email with your address.

Get immediate, accurate protection

Receive real-time threat updates from the SonicWall GRID network and ensure delivery of good email. The GRID network collects and analyzes information from industry threat lists, performs rigorous testing and evaluation of millions of emails every day, and establishes reputation scores for senders and content, identifying new threats as they occur.

Safeguard your network with the latest security updates

Ensure your anti-spyware and anti-virus is up to date, with SonicWall GRID Anti-Virus and premium anti-virus signatures from industry partners such as McAfee, Kaspersky, and Cyren. Safeguard your network from the time a new virus outbreak occurs until the time an anti-virus signature update is available with the predictive technology of SonicWall Time-Zero virus protection.

Seamlessly ensure compliance management and email encryption

Comply with regulatory mandates using advanced compliance scanning, management and, optionally, email encryption, to prevent confidential data leaks, regulatory violations and to ensure the secure exchange of sensitive data. Configure policies at the organizational level to scan outbound email content and attachments for sensitive data and route email for approval, archiving or encryption. Track encrypted email to confirm time of receipt and time opened. Recipient receives a notification email with easy instructions to log into a secure portal to read or securely download the email. No additional client software is necessary and, unlike competitive solutions, the encrypted email may be accessed and read from mobile devices and laptops.

Gain efficient and easy-to-use security

Get automatic spam filter updates and easily synchronize with LDAP. Achieve simple email management with customizable, at-a-glance dashboard. Multi-tenancy support allows large enterprise or managed service provider deployments with multiple departments or customers to establish organizational units with one or multiple domains. The deployment may be centrally managed, but still allows a given organizational unit to have its own users, sub-administrators, policy rules, junk boxes and more. Delegate spam management to end users and give them the freedom to personalize the aggressiveness of their spam-detection settings, while IT continues to control the overall level of security enforcement. Easily customize granular or system-wide reports and charts on threats, compliance, policy, connection management and more, with the customizable, drag and drop dashboard. Automatically generate reports as required.

How it Works:

SonicWall Email Security Deployments

Deployment Options:

SonicWall Email Security Deployments

The highly flexible architecture of SonicWall Email Security enables deployments in organizations that require a highly scalable, redundant and distributed email protection solution that can be centrally managed. SonicWall Email Security can be deployed in either all-in-one (Figure 1) or split mode (Figure 2).

In split mode, systems may be configured as a remote analyzer or a control center. In a typical split-mode setup, one or more remote analyzers is connected to a control center. The remote analyzer receives email from one or more domains and applies connection management, email filtering (anti-spam, anti-phishing and anti-virus) and advanced policy techniques to deliver benign email to the downstream email server. The control center centrally manages all remote analyzers and collects and stores junk email from the remote analyzers. Centralized management includes reporting and monitoring of all related systems. This paradigm allows the solution to costeffectively scale and protect both inbound and outbound email for growing organizations. Using SonicWall Email Security Virtual Appliances, split mode can be fully deployed on one or multiple servers for optimal efficiencies of scale.

Flexible, Scalable Deployment Options

All-in-one configuration (Figure 1) In an all-in-one configuration, filtering and management take place on the same system.

High availability deployment (Figure 2) For load balancing and redundancy, split mode enables organizations to filter at the network perimeter while providing centralized control. Administrators can easily synchronize SonicWall Email Security across multiple LDAP servers in distributed and hosted environments for scalable deployment.

Flexible, Scalable Deployment Options
