News Release - Engate Delivers Next Generation, Connection-Level Protection Against Image Spam


Engate’s Network Profiling Connection Management Technology Preemptively Stops All Variations of Image Spam at the Connection Level


Reno, NV – March 15, 2007 — Engate Technology Corporation, a leading supplier of next generation network profiling connection management security solutions, today reported that its flagship product, Engate MailSentinel™, delivers the industry’s highest level accuracy of 99% in blocking all variations of image spam at the connection level -- helping organizations save bandwidth, conserve network resources and optimize response times for messaging systems. Engate MailSentinel™ is available immediately to service providers and enterprises and can be licensed to anti-spam software, security appliance, router, firewall, and unified threat management vendors.


"As the size, frequency and diversity of image spam continues to surge, organizations are realizing the strain on their messaging systems which is causing disruptions in the delivery of legitimate email,” said Chenxi Wang, Principal Analyst, Forrester Research. “Simply scaling mail servers to constantly meet these rising amounts of image spam is not practical or cost effective. Using next generation network profiling and connection management solutions like Engate’s will enable companies to significantly reduce the load on their servers by preemptively stopping large unwanted traffic at the connection level, ensuring the proficient delivery of legitimate email.”


"Traditional signature-based, scanning and filtering solutions are failing against image spam because they can't keep up with spammer's rapidly changing randomization techniques,” said Rich White, Chief Technology Officer, Engate Technology Corporation. “Engate’s proprietary technology transcends today’s anti-spam solutions with an innovative and preemptive approach that cannot be circumvented by present and future spam onslaughts. Our patent-pending network profiling connection management technology is impervious to all threats, including image spam, because it uses proprietary techniques and source information that cannot be forged or adapted by spammers’ progressive tactics, delivering superior accuracy to reputation and filter solutions in the market.”


Engate Delivers Industry-Leading Protection Against Image Spam
Image-based spam embeds a .gif or .jpeg image in the email message rather than using text, making it difficult for contemporary solutions to recognize the malicious and unwanted traffic entering into the network. As image recognition and traditional anti-spam solutions continue to play catch up, spammer’s use innovative randomization techniques where each message is modified to covertly bypass scanning and filtering solutions. As image spam is typically ten times larger than a text-based message, the problem intensifies as email servers become overloaded with the growing size and volume of spam, disrupting the efficient delivery of legitimate email.


Using eight patent-pending technologies, Engate MailSentinel™ ensures the highest protection against advanced image-based spam by focusing on the source, rather than the message. Engate uniquely profiles an entire spamming network, analyzing every IP that has spammed and not spammed within the network, and establishes ‘smart’ rules to block malicious email at the connection level. Engate is impervious to threats because it uses unique protocol and network analysis that cannot be misrepresented, circumvented or adapted by a spammers’ present and future ingenuity. Engate MailSentinel™ segregates between legitimate mail servers, and all other network functions, thereby making accurate judgments about the legitimacy of inbound mail. Engate uniquely functions at 99% accuracy at the protocol level, without throttling, capturing, storing or reading email content. This empowers Engate customers to achieve unmatched performance with no risk of delay in mail delivery.

Engate Delivers Incremental Value to Security Software and Hardware OEMs

Engate MailSentinel™ adds incremental value to anti-spam software, security appliance, router, firewall, and unified threat management systems by radically reducing the volume of unwanted traffic prior to their receipt at the destination mail systems. Once illicit email is interdicted at the connection level, Engate directs legitimate mail to the mail transfer agent, and if desired, filtering for objectionable content. The result is drastically smaller volumes of email that require application layer filtering, as well as a reduced load on the email infrastructure, setting a new benchmark for anti-spam protection, performance and customer satisfaction.
