Colonial Properties Trust Selects StealthWatch by Lancope for Network Integrity and Sarbanes-Oxley Compliance

Gains Behavior-based Network Control, Optimizes Security Posture and Verifies Network Health

ATLANTA, MARCH 7, 2005 - Lancope, Inc., the leading provider of Network Behavior Analysis (NBA) and Response solutions, today announced that Colonial Properties Trust (NYSE: CLP), a diversified real estate investment trusts (REIT), has deployed StealthWatch to gain better control of the network, audit network health and optimize the security posture of the network in compliance with Sarbanes-Oxley. Colonial Properties owns and manages 168 multifamily, office and retail properties in the Sunbelt.

"Because security traditionally represents less than 5% of IT budgets, most companies simply do not have the resources to have one person dedicated to managing an intrusion detection system. Consequently we looked to companies like Lancope with solutions that are easy-to-use, reliable and require minimal maintenance," said Eric Smithson, systems engineer with Colonial Properties. "In addition, StealthWatch is a scalable solution that can grow with our company as we move forward in expanding our network."

Smithson added, "One of the driving needs for a solution like StealthWatch is that it enables us to comply with Sarbanes-Oxley by providing us with the necessary internal controls over enterprise data integrity."

"Upon implementation, StealthWatch immediately alerted us to port-scanning activities on our network and identified several infected machines that had entered through VPN access," stated Benjie Reaves, network manager for Colonial Properties.

"StealthWatch allows us to know what is continuously happening on the network," said Reaves. "Similar to a mechanic who needs the right tools to fix a car, we use StealthWatch to fix our network."

According to Smithson, "StealthWatch provides critical Network Intelligence to give us awareness and control of what is happening on the network. By gaining the power of knowledge through network insight, StealthWatch allows us to breathe easier about the health of our network."
