Schlumberger Launches DeXa.Trust for Improved Security Management

Turnkey Security Administration Tools Detect and Deter Threats, Incursions

London, April 29, 2003 – Schlumberger (NYSE: SLB) announced today that its information technology (IT) business segment, SchlumbergerSema, has launched a new IT security offering that provides a broad set of administration and management services that enhance the protection of complex enterprise systems. The new offering, DeXa.Trust, is another element in the complete Enterprise Security Solutions of Schlumberger, which provides integrated consulting, systems integration and managed services for enterprise security needs.

“Security will remain on the short list of IT issues of concern to enterprises,” according to Kelly Kavanagh, industry analyst, Gartner, in an October 2002 Strategic Forecast Statement. “Enterprises will invest in technology such as intrusion detection and prevention to improve and maintain the integrity of their networks, access points and network applications.”

DeXa.Trust is part of the DeXa* Suite of Services, a collection of complementary information infrastructure solutions. The DeXa.Trust Integrated Security Administrator (ISA) enables enterprise-wide network security device monitoring to collect, correlate, analyze and react promptly to threats or breaches against company assets. At its core, DeXa.Trust incorporates Managed Security Services including firewalls, intrusion detection, VPN and the latest provisioning technology to automate the process whereby access to company assets such as office equipment, email and computers is granted or restricted (de-provisioning) according to employee status.

The scale to which SchlumbergerSema can manage security and IT service operations is evident in its successful management of the IT infrastructure for the 2002 Olympic Winter Games in Salt Lake City. Deploying the SchlumbergerSema DeXa.Trust Integrated Security Administrator, Schlumberger – the Worldwide IT Partner for the Olympic Games – will provide managed IT and security services for the next three Olympic Games, including Athens in 2004, Turin in 2006 and Beijing in 2008.

In North America, the market for security services will grow from $4.108 billion in 2001 to $8.999 billion in 2006, a compound annual growth rate of 17 percent, with managed security services experiencing the highest growth rate, just over 20 percent, from 2001-2006. DeXa.Trust offers a turnkey solution whereby organizations can choose to completely or partially outsource their network security management. With the DeXa.Trust solution, companies can effectively fortify and enforce their existing security policies using comprehensive tools to manage corporate identity and network access.

“With the growing variety of systems within organizations and the need for rapid access to data and resources, companies are keenly interested in DeXa.Trust services,” said Mauricio Arboleda, vice president, Information Security Solutions, SchlumbergerSema. “Now, more than ever, companies require a cost-effective, proactive approach to managing their security environment. DeXa.Trust meets this demand, providing a comprehensive set of services backed by best-of-breed technologies and our consulting capabilities.”

Additional services to complement the DeXa.Trust portfolio include risk assessment, network and performance monitoring, security and event analysis, and reactive services such as incident and litigation response.
