Proofpoint Spam Detection

Spam remains a serious problem today because it continues to be a very profitable business for spammers. Spam takes on various forms from adult content, selling products/services, pharmaceuticals to stock promotions, job offers, etc. These unsolicited messages are a nuisance and can also be offensive to your end-users (particularly adult content). Spammers are constantly pioneering new techniques to bypass email anti-spam filters forcing organizations to invest in anti-spam solutions and filters that can keep up with the evolving approaches. As long as spam makes money, spammers will continue to send out a barrage of unsolicited messages.

Powered by patent-pending Proofpoint MLX machine learning technology, Proofpoint Spam Detection solution examines and filters millions of possible attributes in every email – including message envelope headers and structure, images, sender reputation as well as unstructured content in the message body – to block spam, attachment-based spam (including PDF and image-based spam), while automatically filtering and adapting to new spam attacks as they appear.

Your organization's email spam prevention and protection solution is automatically kept up-to-date via Proofpoint’s cloud-based Dynamic Update Service, ensuring maximum spam detection and protection at all times. Individually controllable spam, adult content, and bulk content scores allow organizations to enforce customized anti-spam email policies, such as zero-tolerance policies against pornographic spam.

Proofpoint Spam Detection solution is multi-lingual and offers outstanding accuracy against spam in any language, including hard-to-analyze, multi-byte character languages such as Japanese and Chinese. Anti-spam email policies can be customized at the global, group, and end-user levels with full integration to LDAP or Active Directory for easy, on-going maintenance.

Proofpoint Spam Detection Solution Key Capabilities:

Contextual, Lexical, and Image-based Analysis and Support for Single-Byte and Double-Byte Languages: Proofpoint MLX spam prevention technology examines the email content and context of messages using structural tests, single-byte and double-byte language content inspection, pornographic detection, malicious URL detection, image analysis, reputation analysis and any custom anti-spam email policies administrators have defined.
Bounce Management: Backscatter: The barrage of non-delivery report messages (NDRs) and auto-responses caused by spammers spoofing an organization's email addresses – has long been a serious problem for most organizations. Proofpoint's anti-spam filtering solution supports the latest BATV (Bounce Address Tag Validation) specification to tag outbound messages and to validate incoming NDRs against those tags to block backscatter. In addition, Proofpoint MLX spam prevention techniques block invalid NDRs in cases where BATV isn't or can't be used (e.g., in the case of email forwarded from external domains).
Administrator Customization: Different anti-spam email policies can easily be configured for different groups of end-users or domains. All anti-spam email policies can be customized at a global, group, or user level with full integration to LDAP or Active Directory to simplify on-going administration.
Outstanding End-User Control of Anti-Spam Filter Preferences: Proofpoint anti-spam solution provides end-users with easy, "self-service" control over their personal anti-spam filter preferences through features including:

Personalized spam quarantines and quarantine digest reports
Personalized anti-spam safelists and blocklists. (Global lists override end-user lists)
Web-based spam quarantine and profile administration
Ability to opt in and out of different anti-spam policies (as permitted by administrator-configurable settings)
