Unified e-mail security for enterprises

ProofPoint : 07 October, 2008  (New Product)
Proofpoint 5.5 release enhanced to include wider language support, data loss prevention features and backscatter spam protection
Proofpoint has introduced Proofpoint 5.5, the latest version of its integrated email and data security solution. Proofpoint 5.5's unified email security platform—which can be deployed in on-demand (SaaS), on-premises, or hybrid configurations—defends against inbound spam and viruses, prevents leaks of confidential and private data, encrypts sensitive email contents and helps companies optimise the performance and usability of their entire email infrastructure.

Significant enhancements in Proofpoint 5.5 help reduce a wide variety of email risks associated with inbound threats and outbound data loss while improving ease-of-use for administrators and end-users. In addition, Proofpoint 5.5 incorporates expanded international capabilities including a fully localised Japanese language version of Proofpoint's administrative interface, enhanced language detection features and data loss prevention capabilities for multi-byte languages.

"Proofpoint 5.5 is truly a global offering," said Sandra Vaughan, senior vice president of marketing and products for Proofpoint. "With outstanding performance against multi-lingual spam and a wide selection of end-user interfaces, Proofpoint has long been the email and data security solution of choice for global enterprises. Enhanced internationalisation of our solution combined with new security and data loss prevention features make Proofpoint 5.5 the ideal solution for organisations in any geography."

BATV Specification Support for Enhanced Protection against Spam Backscatter
Proofpoint 5.5 offers improved bounce management features that block 100 percent of "backscatter" spam. As spam volumes have grown, backscatter—the barrage of non-delivery report messages (NDRs) and auto-responses caused by spammers spoofing an organisation's email addresses—has become an increasingly serious problem for most organisations.

To combat this threat, Proofpoint 5.5 incorporates support for the latest BATV (Bounce Address Tag Validation) specification. BATV tags outbound messages and then validates incoming NDRs and auto-responses against those tags to block Backscatter caused by spam attacks.

Previous generations of the Proofpoint MLX anti-spam engine have blocked 80% or more of all Backscatter using patent-pending machine learning techniques. The new bounce management features allow organisations to block the remaining 20 percent of Backscatter and improve overall spam detection accuracy beyond the industry-leading 99.8%+ spam detection rate delivered by MLX alone.

The new version enhances Proofpoint's suitability for global deployments with an array of internationalisation and non-English language features beyond the multi-lingual end-user interfaces and advanced, non-English spam detection capabilities of previous versions. These features are especially important as international requirements for data protection become increasingly complex.

A new localisation framework allows Proofpoint 5.5 to support non-English languages and international (multi-byte) character sets in every part of the product including policy definitions, dictionaries and annotations.

With the introduction of Proofpoint 5.5, Proofpoint's entire administrative GUI, product documentation and online help have been fully translated into the Japanese language, providing many benefits for Proofpoint's Japan-based and multinational customers. As with Proofpoint's end-user interfaces, each administrator's language preferences can be set on an individual basis. Additional international language administrative interfaces including French, German and Spanish will be made available with future product releases.

Proofpoint's policy and content scanning engines now detect and "understand" text in any language, including multi-byte languages such as Japanese. New capabilities include:.

* Data loss prevention and email encryption policies enforced by the Proofpoint Regulatory Compliance.
* Proofpoint Secure Messaging modules can match non-English keywords and dictionary items written in international character sets including Japanese, Chinese and Cyrillic (Russian).
* Proofpoint Regulatory Compliance includes two new "smart identifiers" for accurately detecting Japan's Jyuminhyou (residence registration) and driver's license IDs. This module also accurately detects Japanese and international credit card numbers and a wide variety of other identifiers for protecting private financial, healthcare and identify information.
* Administrators can create policies that are triggered based on the language detected in the content of an email. For example, attach language-specific disclaimers or signatures to an outbound message depending upon the language in which it was written.
* International data loss prevention policies for email can be applied to outbound HTTP (including web-based email, blog postings and message board submissions) and FTP traffic using the Proofpoint Network Content Sentry module.
* Email end-users can select their own preferred language for interfaces including message digests and web-based quarantines. End users can select from Chinese, Dutch, English, German, Finnish, French, Italian, Japanese, Portuguese, Russian, Spanish and Swedish versions.

In addition to the international data loss prevention features described previously, Proofpoint 5.5 also includes enhanced DLP workflow features for improved incident status tracking.

Administrators, compliance officers or other appropriate business users can review, comment upon and track outbound policy violations. The new features automate many of the processes associated with remediating data loss prevention policy violations, saving organisations time and money in the process.

New features let compliance administrators:.

* Track the status of outbound policy violations.
* Mark messages with a variety of status labels (eg, in progress, escalated, resolved) and add their own labels.
* Add comments to messages and display message status in the Proofpoint's quarantined message list.
* Search for messages by specific status and export the matching messages to a spreadsheet for later review.
* View comment trails for specific messages.

The advanced message tracking and log analysis features delivered by the optional Proofpoint Smart Search module have been enhanced. Proofpoint Smart Search now makes it easier to track messages and this module can be deployed with other Proofpoint modules or as a separate appliance. Proofpoint Smart Search allows administrators and non-technical help desk personnel to trace messages in real-time, directly from the Proofpoint administrative interface. New capabilities for Proofpoint Smart Search in version 5.5 include:.

* Simplified search: Simply enter information such as sender, recipients or subject to quickly search for messages.
* Enhanced drill down: Start with summary results, drill down for additional detail all the way to the raw log file level, if desired.
* Enhanced export: Search results can be exported in CSV or XML format.
