Protect your infrastructure from email threats and compliance violations with powerful, easy-to-use solutions.

Email is crucial for your business communication, but it can also expose your business to sabotage and productivity drains if email-based threats such as spam, phishing, spoofing, viruses and zombies flood your mail servers and user inboxes. What's more, government regulations now hold your business accountable for protecting confidential data and ensuring it is not leaked and that email containing sensitive customer data or confidential information is securely exchanged. Whether your organization is a growing small-to medium-sized business (SMB), a large, distributed enterprise or a managed service provider (MSP), you need a cost-effective way to deploy email security and encryption, and the scalability to easily grow capacity for-and delegate management across- organizational units and domains.


SonicWall Email Security appliances and software provide superior protection from inbound and outbound email threats and compliance violations by scanning all inbound and outbound email content and attachments for sensitive data, delivering real-time protection from spam, phishing, viruses, malicious URLs, spoofing, zombies, directory harvest (DHA), Denial of Service (DoS) and other attacks. The solution leverages multiple, patented1 SonicWall threat detection techniques and a unique, worldwide attack identification and monitoring network.

The solution also includes Domainbased Message Authentication, DKIM (Domain Keys Identified Mail), SPF (Sender Policy Framework), Reporting and Conformance (DMARC), a powerful email authentication method that helps identify spoofed mail, reducing spam and phishing attacks, and also reports on sources and senders of email, so you can identify and shut down unauthorized senders falsifying email with your address and protect your brand. In addition, it prevents confidential data leaks and regulatory violations with advanced compliance scanning and management, including integrated email encryption cloud service to ensure secure exchange of sensitive data.

SonicWall Email Security is a flexible solution that deploys as a scalable hardware appliance, virtual appliance or software optimized for Microsoft® Windows Server® , and it scales easily to protect 10 to 100,000 mailboxes. Large enterprises can configure the solution for high availability in split mode to centrally and reliably manage large-scale deployments.

Administration of the Email Security solution is intuitive, quick and simple. You can safely delegate spam management to end users, while still retaining ultimate control over security enforcement. You can also easily manage user and group accounts with seamless multi-LDAP synchronization. For large, distributed environments, multi-tenancy support lets you delegate sub-administrators to manage settings at multiple organizational units (such as enterprise divisions or MSP customers) within a single Email Security deployment.
