                    BLUE COAT TO ACQUIRE PERMEO TECHNOLOGIES

   TECHNOLOGY TO EXTEND BLUE COAT PROXY INFRASTRUCTURE TO ENTERPRISE ENDPOINTS
          WITH ON-DEMAND DELIVERY OF APPLICATION AND SECURITY SERVICES

    SUNNYVALE, Calif., Jan. 3 /PRNewswire-FirstCall/ -- Blue Coat(R) Systems
(Nasdaq: BCSI), the leader in secure content and application delivery, today
announced it has signed a definitive agreement to acquire Permeo Technologies,
Inc., a privately-held provider of on-demand endpoint access, security and
information protection solutions, for approximately $60.8 million, including
approximately $13.4 million in cash and approximately $47.4 million in Blue Coat
common stock, based on the closing price of Blue Coat common stock of $45.72 on
December 30, 2005. The consideration, which is for all of Permeo's securities
other than unvested stock options, is subject to adjustment based on the average
closing price of Blue Coat common stock over a 10 trading day period prior to
the closing date of the transaction, as well as certain adjustments as provided
in the merger agreement. Transaction costs and the value of unvested stock
options, which are being assumed by Blue Coat in the acquisition, are not
included in the $60.8 million above. The closing of the acquisition is subject
to customary conditions, and is expected to occur in approximately 60 days.

    The acquisition will result in the integration of Permeo's on-demand
endpoint access, security and information protection technology with the Blue
Coat ProxySG(TM) family of proxy appliances. Blue Coat intends to leverage the
Permeo technology to extend its proxy infrastructure to provide advanced levels
of protection and control to any endpoint connecting to enterprise applications.

    "The enterprise workforce is increasingly more mobile and outside of the
traditional corporate network but still requires the same level of protection
and control," said Brian NeSmith, president and chief executive officer of Blue
Coat Systems. "The technology from Permeo helps us extend our proxy
infrastructure for application and security services all the way to the endpoint
of the virtual enterprise."

    "Permeo has provided secure access and information protection solutions for
both managed and unmanaged endpoints to many of the world's largest
enterprises," said Michael S. Bennett, chief executive officer, Permeo
Technologies. "Combining our on-demand delivery technology for application and
security services with Blue Coat's market-leading proxy infrastructure solutions
will give customers a whole new level of end-to-end secure content and
application delivery."
