SEATTLE--(BUSINESS WIRE)--April 3, 1997--

Aventail to include CyberSafe's award-winning authentication 

technology with their S5 product series

Aventail Corp. and CyberSafe Corp. announced today the availability of CyberSafe Challenger(TM) suite of authentication tools in Aventail's S5 product series.

The integration of CyberSafe Challenger within the Aventail S5 product series provides users with an enterprise security foundation and Single SignOn (SSO) to Aventail's products. CyberSafe Challenger is based on open standards and includes support for the Kerberos network security protocol. This technology integration delivers encryption and authentication using Kerberos for TCP and most UDP applications.

Aventail's S5 product series -- Aventail MobileVPN, Aventail PartnerVPN, Aventail Internet Policy Manager, and Aventail AutoSOCKS -- are the only SOCKS v5 security solutions to include support for multiple authentication and encryption methods.

"We are excited about working with CyberSafe, one of the market leaders for authentication software," said Evan Kaplan, president and CEO of Aventail Corp. "The combination of CyberSafe's technology with our S5 product series gives corporations the confidence that their users are truly authorized to access confidential data within their network. This is critical for companies who are looking to build a Virtual Private Network or to manage their employees' access to the Internet."

"CyberSafe is encouraged by the collaborative efforts of companies like Aventail," said Dr. Daniel Webb, president and CEO of CyberSafe Corp. "Through integration of our CyberSafe Application Security Toolkit, Aventail's customers gain Single SignOn access to previously unsecured networks."
