CSI Joins UBM TechWeb's Portfolio of Leading Information Security Products

NEW YORK, May 23, 2011 -

- Synergies with Sister-UBM Division Provide Greater Benefits to Security
Community

UBM Live announced today that select products within CSI (The Computer
Security Institute) have transitioned to its sister company, UBM TechWeb.

Based on synergies with UBM TechWeb's IT security portfolio, such as
Black Hat(R) series of events and DarkReading.com, the CSI Web site at
goCSI.com and CSI-branded webinars will continue under UBM TechWeb's
management. Robert Richardson, Director of CSI, joins the UBM TechWeb team
and will focus on online initiatives in the IT security arena. CSI Annual,
scheduled to take place November 6-11, 2011, has been cancelled; in addition,
new CSI memberships and renewals will not be accepted pending re-direction.

"Thirty-seven years ago, CSI was at the forefront of building community
in information security," said John Stuttard, SVP of UBM Live, "Changing
times and current demands have dictated that we need to change our current
model and discontinue offerings that are better served by other resources -
many of which reside within UBM TechWeb's portfolio."

EVP and General Manager of UBM TechWeb, Katherine Astromoff comments,
"Joining CSI with brands such as Black Hat and DarkReading.com reinforces UBM
TechWeb's reputation as IT security professionals' best resource for
information and solutions for their workday challenges."

CSI's online offerings will continue and the next CSI Webinar sponsored
by Intel will take place June 2, 2011 at 2:00PM ET. Targeting IT security
professionals in government agencies and focusing on ICAM, complete details
including registration information are currently available on
www.goCSI.com/Webinars.
