Microsoft India – Tata Teleservices Case Study


Published on

Tata Teleservices Limited (TTSL) is a leading telecommunications provider in India with 50 million subscribers and a goal to reach 100 million subscribers by 2011. As the company grew, it wanted to improve remote access to software and corporate data, in addition to improving secure communications with its employees, partners, vendors, and distributors—all while shoring up its endpoint security to prevent data leakage and comply with strict internal security policies. By implementing Microsoft business-ready security solutions, including Microsoft Intelligent Application Gateway 2007, Microsoft Internet Security and Acceleration Server 2006, and Windows Server 2003 Rights Management Services, TTSL has provided employees with more secure, remote access to data even as it reduces costs by U.S.$2 million, improved compliance with internal security policies, and simplified IT management.
