Tata Communications has announced major leadership changes, approving the appointments of Rupesh Chokshi as EVP of Network Services and Vivek Srivastava as EVP of Cloud and Cybersecurity. These strategic hires follow the retirement of Sivasamban Natarajan and the resignation of CTO Genius Wong.
MUMBAI, India — Tata Communications Limited has announced a comprehensive restructuring of its senior executive tier, introducing major leadership transitions across its core network, cloud, and cybersecurity business divisions. In a regulatory compliance disclosure filed on Tuesday, June 30, 2026, the company confirmed the retirement and resignation of two long-standing senior vice presidents alongside the appointment of two incoming global enterprise executives.
The board-approved Tata Communications leadership changes come at a critical time as the international digital ecosystem enabler aggressively repositions its worldwide infrastructure to capture enterprise demand for Artificial Intelligence (AI) and cloud-native software-defined services.
Executive Departures in Operations and Technology
The statutory filing submitted to Indian market regulators highlights the formal conclusion of the tenures of two prominent senior management personnel. Mr. Sivasamban Natarajan formally retired from his role as Executive Vice President and Head of Operations, effective June 30, 2026.
Simultaneously, Ms. Genius Wong submitted her formal resignation from her position as Executive Vice President of Core and Next-Gen Connectivity Services and Chief Technology Officer (CTO). According to her internal correspondence enclosed within the regulatory records, Ms. Wong will be officially relieved of her operational duties on July 31, 2026, to dedicate time to her personal affairs. The Board of Directors has formally placed on record its structural appreciation for the contributions made by both departing executives during their respective tenures.
Chokshi and Srivastava Appointed to Core Global Portfolios
To fill these critical vacancies and drive next-generation market expansion, the company’s board approved two key appointments based on recommendations from the Nomination and Remuneration Committee:
Rupesh Chokshi (EVP & Global Business Head - Network Services)
Mr. Rupesh Chokshi will take over his full operational portfolio on August 1, 2026. To ensure a smooth transition, he will join the company as Executive Vice President & Global Business Head - Network Services (Designate) starting July 6, 2026.

He most recently served as Senior Vice President and General Manager of Application Security at Akamai Technologies, managing a $1.4 billion business segment. Prior to that, he managed a $2 billion global next-generation network enterprise at AT&T.
Vivek Srivastava (EVP & Business Head - Cloud and Cybersecurity Services)
Mr. Vivek Srivastava will officially assume leadership of the company's cloud and cybersecurity divisions on August 17, 2026.

Impact on Global Enterprise and Investors
For stock market investors and corporate enterprise clients spanning over 190 countries, these foundational Tata Communications leadership changes signal a deliberate pivot toward high-margin software-as-a-service (SaaS) and cybersecurity monetization models.
By onboarding executives with proven track records in managing multi-billion-dollar global businesses, Tata Communications plans to improve its capability to function as the primary digital and cloud backbone for Fortune 500 corporations deploying heavy AI workloads. This transition aims to mitigate the margin pressures typically associated with legacy wholesale telecommunications traffic.
