Caymas Systems Collaborates with TippingPoint and Microsoft to Provide Powerful Network and Application Access Control Solution.

SAN JOSE, Calif. -- Caymas Systems:

Solution is the First to Harness Intrusion Prevention,
     Network Access Protection, and Identity-Based Access Control
                for Powerful Network Security Solution

  Companies Demonstrate Solution at RSA 2006, TippingPoint Booth #823

Caymas Systems, a leader in identity-based access control, today announced integration with Quarantine Protection from TippingPoint, a division of 3Com and the leader in intrusion prevention, and Network Access Protection technology from Microsoft. Together, the companies offer the first clientless solution to combine the power of identity-driven access control, intrusion prevention attack control and security policy enforcement. The integration of Caymas Systems Identity-Driven Access Gateway, TippingPoint Quarantine Protection and Microsoft Network Access Protection blocks network attacks and tightly controls all user behavior to provide a comprehensive attack and access control solution.

TippingPoint Quarantine Protection, which is available today, is an attack control solution that utilizes the TippingPoint Intrusion Prevention Systems to block malicious traffic from entering a network. Quarantine Protection leverages the management system or switch to contain infected end points in an isolated area for remediation, preventing worms, viruses and other attacks from damaging corporate networks. However, as threats and attackers become more sophisticated, the need to tie attack control to device identification has become clear. Attacks can come from authorized users with an infected personal computer or mobile device, or from malicious "insiders" who have credentials to access critical data.

Caymas' identity-based network access control strengthens TippingPoint's attack control capabilities by providing fine-grained access control based on the richest possible set of factors defining a user's identity, including the user's authentication, location, the configuration of their machine and a variety of other factors. With the combined solution, enterprises prevent malicious code from entering their networks, guest users are controlled and contained, and authorized users are not able to intentionally or unintentionally compromise network security.

"The integration of Caymas Systems Identity-Driven Access Gateway with TippingPoint Quarantine Protection is a breakthrough that allows organizations to leverage their existing infrastructure and lockdown access to critical data, applications, and servers," says Marc Willebeek-LeMair, chief technology officer of 3Com. "This powerful solution, based on open standards, provides unprecedented network security that allows enterprises to control attacks and access. We are excited about this relationship because this is the first demonstrated solution that integrates Intrusion Prevention System attack control with identity-based access control."

Microsoft's Network Access Protection technology validates computers against security policies and provides a health check prior to being granted access to the corporate network. Non-compliant machines can be re-directed to a quarantined virtual network until they are updated and compliant with policies. Microsoft's Network Access Protection functionality was included in the Beta 1 versions of Windows Vista and Windows Server code-named "Longhorn." The full functionality will be delivered with Windows Vista and Windows Server "Longhorn."

"The Caymas Access Gateway enhances Microsoft's Network Access Protection technology by providing fine-grained access control to corporate resources," said Mike Schutz, group product manager, Microsoft's Security and Access Product Management group. "Together, Microsoft and its partners, such as TippingPoint and Caymas Systems, will develop a wide array of applications and end-to-end solutions around Network Access Protection to better serve customers."

Caymas' Access Gateways control admission to network and application resources based on the identity of both users and their devices, without the need for client software. If a user is using a compromised device or attempts to access an unauthorized resource, activity is blocked and the appropriate action is taken. The combined solution limits network access to authorized users using approved devices and provides fine grained access to application resources based on a comprehensive set of access control policies.

Using the combined TippingPoint, Microsoft and Caymas solution, organizations can securely extend access to both employees and a new class of LAN users--guests, contractors, vendors, even anonymous users--by building access control and threat protection into the network infrastructure.

"Point solutions for intrusion prevention, access control, and data protection can leave gaps in network security," says Sanjay Uppal, vice president of product management and marketing for Caymas Systems. "Combining access control and attack control eliminate these gaps, giving organizations unrivaled control over users, devices, and critical corporate data."

Microsoft Network Access Protection will be available as part of the next version of Windows client and Windows Server "Longhorn."

The Caymas Systems integration with TippingPoint Quarantine Protection and Intrusion Prevention Systems and Microsoft Network Access Protection is showcased at RSA 2006, the premier information security tradeshow, at the San Jose Convention Center February 13-16 at the TippingPoint booth #823.

About Caymas Identity-Driven Access Gateways

The award winning Caymas 220, Caymas 318 and the Caymas 525 use Caymas' unique, patent pending Identity Tagging Architecture to tie access control and network security policy to Identity, based on a comprehensive set of criteria including the Identities of users, devices, locations, and client configurations. Caymas Access Gateways are radically economical, ASIC-based appliances and the only solutions that support from as few as ten to many as thousands of remote and LAN-based users, devices, and resources on a single platform. Only Caymas Access Gateways are fully FIPS 140-2 Validated by the US Government, and award winners for both network access control and SSL VPN remote access.

Caymas Identity-Driven Access Gateways are deployed at three
locations:
1) Enterprise perimeter for SSL VPN remote access and business
   partner extranets,
2) Local Area Network for network admission control and
   guest/contractor access
3) Data center for regulatory compliance, reduced and single sign on,
   and the PKI enablement of applications
