Network Chemistry Raises Standard for WLAN Security Protection

Leading Wireless Security Company Introduces Industry's First Stateful Intrusion Prevention Technology to Automate Threat Protection

REDWOOD CITY, CA -- (MARKET WIRE) -- November 15, 2005 -- Network Chemistry Inc., the wireless security experts, today announced that its award-winning RFprotect™ Distributed product provides the industry's most advanced wireless intrusion detection and prevention (WIDP) technology across the most spectrum usable by 802.11 networks. By scanning nearly ten times as many channels as first generation products and by employing a patent-pending intrusion prevention technique, the upgraded system automatically detects and completely contains all types of malicious devices that similar offerings simply do not see. In doing so, RFprotect Distributed greatly reduces the risk of wireless threats to critical data and network infrastructure.

The advancement to RFprotect Distributed is based on two innovative, patent-pending technologies. Network Chemistry's TotalWatch™ is the most accurate wireless intrusion detection technology available today. It detects more rogue devices by scanning over 220 possible channels, which is nearly ten times more than products using off-the-shelf access point (AP) hardware as sensors. Once a threatening device is detected and assessed, Network Chemistry's UltraShield™ completely prevents the intruder from gaining access to the network or laptops. A new stateful prevention technology that is superior to stateless approaches, UltraShield goes beyond rogue AP protection to also contain unauthorized clients and ad-hocs even when they are roaming. Network Chemistry is first to deliver these critical innovations due to its unique purpose-built wireless surveillance sensors, now also available with dual full-spectrum radios for parallel detection and prevention functions.

"Enterprises are demanding greater detection and prevention from wireless threats, and these new RFprotect Distributed innovations squarely meet the need," said Brian de Haaff, vice president of product management and marketing at Network Chemistry. "First generation WIDP products have proven ineffective because they do not see rogues hiding on the out-of-region or lesser-used channels, and they can not prevent most intrusions. As we have learned from wired-side security, enterprise needs have evolved to require highly effective intrusion prevention on top of intrusion detection. RFprotect Distributed meets this requirement for the world's largest enterprises and most security-conscious government agencies."

Intrusion Detection Across All Channels, All the Time

TotalWatch is the industry's most accurate and thorough wireless intrusion detection technology, enabling RFprotect Distributed to scan over 220 channels across the frequency spectrum usable by 802.11 networks. The system's comprehensive scanning capabilities are enabled by Network Chemistry's proprietary sensor hardware, which is purpose-built for wireless surveillance. Unlike WIDP sensors using off-the-shelf AP hardware that is limited to scanning one region at a time, TotalWatch scans all 802.11a/b/g channels in the regulatory domains of the U.S., Europe, and Asia, plus the 'gray' channels defined in this spectrum. Gray channels can be used by rogue devices trying to evade detection and are increasingly configurable with off-the-shelf wireless equipment. TotalWatch's ability to scan all regions simultaneously is particularly important to global organizations, where employees are more likely to introduce 'off-region' rogues.

Intrusion Prevention Traps All Rogues, Even When They Roam

UltraShield is the industry's first and only stateful wireless intrusion prevention technology, overcoming the limitations of stateless approaches available up to now. Stateless approaches based on 802.11 that de-authenticate or disassociate packet streams will overload WLANs and are ineffective for containing clients or ad-hocs that re-establish connections quickly. UltraShield actively participates in the network state--first luring malicious devices and then completely isolating them from the rest of the wireless network. The patent-pending technology contains any AP or client, even the most difficult to contain ad-hocs and 'Centrino' laptops. The prevention technique will contain multiple devices simultaneously even when they are roaming, and will not deny service to other authorized WLAN users. UltraShield may be initiated manually or automatically according to a centralized prevention-activation policy. To find a contained device's physical location, RFprotect Distributed supports integrated location mapping displays and the portable companion product, RFprotect Mobile, includes a real-time locating tool.

Providing an even further layer of protection, the RFprotect Distributed sensors are now enhanced with two 802.11a/b/g radios. An industry first, a dual-radio sensor enables one radio to perform continuous intrusion detection scanning while the other performs dedicated intrusion prevention. This enables the system to uniquely contain multiple devices effectively without compromising the scanning and tracking of new threats, a necessity for an environment with an active policy of automated intrusion prevention.


The new dual radio sensor hardware is available now and the upgrade to the RFprotect Distributed software will be available in December 2005. Existing RFprotect Distributed customers with active maintenance contracts will be eligible to receive the upgrade at no additional cost.
