Nippon TCS and Illumio Announce Strategic Partnership to Enhance Corporate Cyber Resilience

Tokyo | April 1, 2026: Nippon Tata Consultancy Services, Ltd. (Headquarters: Minato-ku, Tokyo; Representative Director and President: Satish Thiagarajan; hereinafter referred to as Nippon TCS) announced today that it has entered into a strategic partnership with Illumio (Headquarters: California, USA; CEO: Andrew Rubin), a provider of microsegmentation solutions adopted by leading global companies.

This partnership aims to facilitate the implementation of corporate zero-trust strategies and minimize the impact of breaches. By combining TCS's proven track record in building, operating, and consulting for cybersecurity and infrastructure with the Illumio Platform, which includes "Illumio Segmentation" and "Illumio Insights," organizations will transition to a state where risks are identified and threats are immediately contained.

Overview of the Nippon TCS and Illumio Partnership

• Efficiently outsource Illumio's strengths in one-click isolation and policy automation through TCS's managed services

• Provide optimal engineering and consulting for Illumio's implementation and operation across all areas of the customer's network and cloud

"Assuming Breach": Shifting from Prevention to Containment

In today's corporate network environments, it is crucial to assume that breaches due to cyberattacks will occur and to quickly identify and contain threats, preventing lateral movement. Illumio's "Illumio Insights" solution, based on an AI Security Graph, provides one-click isolation by leveraging Illumio Segmentation along with prioritized risk intelligence. Furthermore, immediate policy enforcement through Illumio Segmentation minimizes the scope of damage during an incident.

Kazuhisa Miyoshi, Chief Information Security Officer (CISO) and Head of Cybersecurity at Nippon TCS, stated:

"In 2025, businesses learned the harsh reality of cyber threats. While not all breaches can be prevented, it is possible to contain attacks before they become catastrophic. By combining TCS's expertise in cybersecurity transformation with Illumio's AI-driven containment, we will stop lateral movement (attackers moving horizontally within the network to progressively expand damage), protect critical operations, and build measurable cyber resilience."
