Executive Summary

Overview
Unum, headquartered in Chattanooga, TN, is one of the world’s leading employee benefits providers and a market leader in disability, group life, long term care, and voluntary benefits. Established in 1848 as Union Mutual, Unum now consists of Unum US and Colonial Life in the United States and Unum UK in the United Kingdom. Ranked 251 on the 2008 Fortune 500, Unum employs about 10,000 people, serves the needs of 171,000 businesses, and protects more than 25 million people worldwide when illness or injury occurs. In 2008, nearly 400,000 new disability claims were processed and $4 billion in disability benefits were paid.

Barriers
A reliable information technology (IT) security posture was required to protect Unum from the constantly evolving threats. Malware and spam had to be blocked from penetrating the company’s computer network, and those that succeeded had to be resolved faster. Threat research and monitoring had to be automated, and endpoint risks controlled. Additional information technology obligations included improving email discovery speed and reliability, complying with increasingly stringent regulations, and controlling rapid data growth and storage costs.

The Solution
Lynda Fleury, Unum’s assistant vice president and chief information security officer, was chartered in 2001 to drive a comprehensive enterprise security initiative that aligned Unum’s security posture to the continually changing threat landscape. First, Unum’s security monitoring and management processes were outsourced to Symantec Managed Security Services. Second, for email archiving and e-discovery, the Unum team implemented Symantec Enterprise Vault, including Discovery Accelerator and Microsoft Exchange Journaling, with the help of Symantec Consulting Services. Third, to improve compliance with regulatory and policy standards, the team chose Symantec Enterprise Security Manager. Fourth, messaging security was outsourced using MessageLabs Hosted Email Solutions from Symantec. Fifth, Symantec DeepSight Threat Management System was added to provide actionable intelligence about current security threats. Finally, Symantec Web Gateway appliances were deployed to automate Web gateway security.
