Email Security Gateway Deployment
Email Security Gateway Deployment
Deployment and Installation Center | Email Security Solutions | Version 7.8.x
Websense® Email Security Gateway provides maximum protection for email systems to prevent malicious threats from entering an organization's network. Email Security provides comprehensive on-premises security hosted on a Websense appliance (V10000 G2, V10000 G3, V5000 G2, or X10G). Email Security management functions reside on a separate Windows server in the TRITON® Unified Security Center (TRITON console).
Email Security Gateway may also be deployed on a virtual appliance using a VMware platform (ESXi v4.0 or later). The appliance image is available for download from MyWebsense in an open virtualization format (OVF) package. A TRITON manager installed on a separate Windows machine is required for Email Security Gateway administration functions in this deployment. A virtual appliance may not be clustered with a V- or X-Series appliance. See the virtual appliance Quick Start Guide for deployment and configuration information.
Each email message is processed by a robust set of analytics to prevent malicious threats from entering a network. Custom content filters allow Email Security to analyze messages based on administrator-specified message attribute conditions. Commercial bulk email analysis can determine whether a message has been sent from a third-party bulk email management company or directly from a business. Inbound, outbound, and internal email policies can be applied to user-defined sets of senders and recipients.
A Websense Email Security Gateway Anywhere deployment adds support for a hybrid service pre-filtering capability "in the cloud," which analyzes the characteristics of incoming email against a Websense database of known threats.
Enhance your security by adding Websense ThreatScope, a set of cloud-based functions, to your Email Security Gateway Anywhere subscription:
*
URL sandboxing
*
File sandboxing
*
Phishing detection
URL sandboxing provides real-time analysis of uncategorized URLs that are embedded in Email Security Gateway inbound mail. File sandboxing inspects email attachment file types that commonly contain security threats (including .exe, .pdf, .xls, .xlsx, .doc, .docx, .ppt, .pptx, and archive files). Phishing detection and education provides cloud-based analysis of an inbound message for phishing email characteristics. Options for handling suspected phishing mail include blocking the delivery or replacing the mail with a phishing education message. See Email Security Gateway Help for details.
Integration with Data Security provides valuable data loss protection (DLP) features to protect an organization's most sensitive data and facilitate message encryption. Policies configured in the Data Security manager can detect the presence of company data and block the transmission of that data via email. Data Security can also determine whether a message should be encrypted and pass the message to an encryption server.
If your network includes Websense Web Security, you can also use its URL analysis function. Email Security Gateway queries the Websense URL category master database and determines the risk level of a URL found in an email message.
Logging and reporting capabilities allow an organization to view system and message status and generate reports of system and email traffic activity.
A Personal Email Manager facility allows authorized end users to release email messages that Email Security policy has blocked but that may be safe to deliver. End users can maintain personal Always Block and Always Permit lists of email addresses to simplify message delivery. User account management capabilities allow multiple email account control and the delegation of email account management to other individuals.
