Determina Delivers Only Solution to Protect Enterprises From Dasher Worm and Its Variants Without Updates

Award-Winning Memory Firewall Technology Proactively Protects Customers Against Keyloggers, Rootkits, and Botnets Until Patches Can Be Deployed

REDWOOD CITY, Calif., Dec. 16 -- Determina(TM) Inc. today announced that its patent-pending Vulnerability Protection Suite (VPS) is the only proactive security solution available that can stop the Dasher worm before it can execute a single line of malicious code on a vulnerable system. The Dasher worm, along with Dasher.b and other variants, is current spreading among unpatched systems worldwide and acting as a delivery mechanism for rootkits, keyloggers, and malware that allow attackers to gain full remote control of affected servers. VPS also protects against the two critical Windows vulnerabilities announced on November 18 and November 22, 2005 that remain unpatched, and any other Dasher variants that may emerge, with no need for signature updates.

"There are countless unpatched systems that Dasher can prey on, and worms spread far faster than network administrators can update threat signatures or patch their systems," said Nand Mulchandani, VP of Marketing, Determina. "From the moment our Vulnerability Protection Suite is deployed, enterprises are always covered against Dasher and its variants -- or any other attack on a specific vulnerability -- allowing them to protect themselves without the downtime necessitated by the patching process."

Determina Vulnerability Protection Suite (VPS): Real-Time Vulnerability Protection
Determina Vulnerability Protection Suite (VPS) is a breakthrough approach to security. Instead of focusing on the traditional, reactive method of chasing down attacks after they happen, VPS focuses on eliminating and protecting the vulnerabilities in systems. By protecting against both known and unknown vulnerabilities, enterprises can protect themselves against any attacks against a particular vulnerability, and can patch against these vulnerabilities on their own schedule without disruption to business operations.

Unlike attack-oriented security technologies, vulnerability protection offers customers the ability to comprehensively address the security and operational issues around security and patching. The Determina VPS suite offers comprehensive vulnerability protection though its two products: Memory Firewall(TM), which provides proactive, zero-day protection for the most dangerous class of vulnerabilities, and LiveShield(TM), which provides precise vulnerability protection in real-time.

Determina VPS consists of two products that provide complimentary vulnerability coverage:

Memory Firewall(TM) provides proactive protection for the most dangerous class of security vulnerabilities including "memory-based" vulnerabilities such as buffer overflows. Memory Firewall provides true "zero- day" protection against attacks on these vulnerabilities.

LiveShield(TM) provides precise vulnerability protection in real time. LiveShield(TM) enables customers to protect systems in real time against vulnerabilities without a reboot or downtime. This enables customers to dramatically shrink their vulnerability window to allow them to patch their systems on their schedule

With Determina VPS, customers no longer have to worry about both hackers and mass worm attacks taking advantage of software flaws and vulnerabilities in their enterprise infrastructure. VPS also gives them strong security protection that allows them to patch and update their systems on their schedule, instead of when the hackers and worm writers force them to.
