Networking equipment maker Cisco Systems is buying SSL
VPN technology company Twingo Systems for $5m.
The deal will add Twingo's Virtual Secure Desktop technology to
Cisco's VPN 3000 Concentrator product. The new technology will
make it easier for Cisco to clean up after SSL (Secure Sockets
Layer) VPN (virtual private network) sessions on insecure, remote
computers by removing sensitive information stored in temporary
files, web browser caches, cookies and e-mail.
First released in July 2003, the Virtual Secure Desktop creates
a virtual desktop environment on computers using SSL VPN to connect
to sensitive corporate networks. Information passed back and forth
during the SSL VPN session is stored in encrypted form on the
virtual desktop and erased from the machine at the conclusion of
the session.
Privately held Twingo already has deals with other leading SSL
VPN makers, including Aventail and Array Networks.
After focusing exclusively on internet protocol security VPNs
for years, Cisco unveiled its own SSL VPN, called WebVPN in
November. SSL VPNs are increasingly popular, especially for mobile
workers who wish to connect to office networks from airport kiosks
or other insecure systems.
As opposed to VPNs that use IPsec, SSL VPNs are typically
"clientless," meaning they do not require a separate software
application to be installed on the remote user's machine. They also
rely on the SSL protocol, which is a part of most common web
servers and web browsers and widely used to secure e-commerce
transactions.
Cisco expects to complete its acquisition of Twingo in the third
quarter of its fiscal year, which ends in July. Twingo will be
added to Cisco's VPN & Security Business Unit.
