ALDN Aladdin Knowledge Systems Ltd (MM)

CHICAGO, Nov. 2 /PRNewswire-FirstCall/ -- Aladdin Knowledge Systems (NASDAQ:ALDN), the worldwide leader in Software Digital Rights Management (DRM) and USB-based authentication solutions, and a leading innovator in enterprise secure content management, today announced a new Aladdin eSafe Mobile Content Security Gateway (MCSG) designed specifically for cellular providers to offer unmatched protection against the growing number of mobile viruses and spam. (Logo: http://www.newscom.com/cgi-bin/prnh/20040416/CGALADDINLOGO ) Worldwide, more than 100 million smartphones were sold in 2004. With most running on Microsoft Windows Mobile, PalmOS or Sybian operating systems, these convenient devices are vulnerable to security threats such as viruses and other malicious code received through various means. Mobile devices are also commonly used as cellular modems connecting mobile computers to the Internet, exposing the users to all common Internet threats, including mobile-specific malicious code. Device-installed security is non-existent or extremely limited and cannot be trusted to prevent operator-wide outbreaks. An operator content security service is the most effective solution both in cost and in practice. Aladdin eSafe MCSG Multi-Layered Approach for Cellular Customers Situated between the Internet and the cellular provider network, Aladdin eSafe MCSG inspects the content of MMS and WAP traffic as well as HTTP and SMTP content. eSafe's multi-layered approach to protection provides comprehensive security against viruses for handheld devices, as well as PC malicious code, email-borne spam and phishing: * Mobile Viruses -- eSafe uses several unique technologies to block zero- hour malicious code, including mobile viruses that travel via MMS or downloads from the Internet. In addition to signature based protection, eSafe uses proactive technologies that perform sophisticated code emulation to inspect executable code in real time to find abnormal behavior. The eSafe Content Security Response Team (CSRT) uses a patented OutbreakSentry(TM) system that monitors MMS and mobile Internet traffic and can catch virus outbreaks in real time. When ever a new threat is discovered, the eSafe CSRT will issue a security update that is automatically updated by eSafe MCSG to block the newly discovered virus or security hole that can be exploited by a virus. * Spam -- eSafe uses 20 different technologies to identify and block spam with high accuracy. eSafe's Advanced Anti-spam blocks more than 96 percent of spam with nearly zero false-positives. This ensures that inbound junk emails will not be transferred to costly MMS messages, not annoy mobile phone users and not clog their phone memory. Outbound Spam is blocked as well, ensuring spammers are not abusing the network or using stolen devices to distribute spam. This also prevents the cellular operator's network from being blacklisted. * Email Security -- eSafe delivers a high level of email security utilizing unique "email reconstruction" technology to prevent potentially dangerous, malformed, damaged and hacked email. eSafe takes each email apart, inspects each section, and then reconstructs the email according to all the relevant RFC standards. This ensures that all emails arriving at the internal mail server will never circumvent security standards. * Phishing -- It is extremely difficult for a novice user to distinguish between legitimate or phishing Web sites. This is especially true when using a limited smartphone Web browser. eSafe contains unique technologies to thwart email phishing attacks and prevent mobile phone users from clicking on email links that will take them to phishing Web sites. Unique Aladdin eSafe MCSG Differentiators * Anti-virus engine that identifies and blocks all Symbian, J2ME, PalmOS, and Windows Mobile/CE malicious code * Identifies and blocks malicious code in all MMS formats (MM1/MM3/MM4/MM7) * Full WAP traffic inspection for mobile and PC malicious code * Multi-layered anti-spam and phishing prevention for email messages * High throughput to support millions of subscribers * Built-in load balancing and fail-over * OutbreakSentry system for MMS and mobile Internet traffic * 24x7 security service with timely updates for new mobile users "Through the Aladdin eSafe MCSG, we now bring the mobile community the same powerful eSafe technologies relied upon by large corporate networks," said Shimon Gruper, vice president of technology for the Aladdin eSafe Business Unit. "A service-based solution is the most practical and efficient, as well as cost effective. By providing stellar security for their customers, cellular providers will stand out as organizations that employ the latest technologies that match the ever-evolving threats entering the mobile network. Aladdin is pleased to offer such a uniquely proactive approach to mobile email and Internet security."
