Tata Group Steps Up Cyber Defence, Pins Battery Localisation to 2027 in Next Phase of Auto Strategy

Tata Group is sharpening its focus on risk management and localisation across its automotive businesses, with Chairman N. Chandrasekaran highlighting execution, supply chain disruptions and cyber security as key vulnerabilities and tying them directly to the next phase of the Group’s mobility strategy.

Speaking to shareholders, Chandrasekaran said a recent cyber incident at Jaguar Land Rover had been addressed but stressed that cyber security is now an industry wide challenge that demands sustained investment rather than one off fixes. The comments underline that the Group is treating cyber resilience as a strategic priority, recognising that attacks on plants, IT systems or connected vehicle platforms can quickly spill over into operations, customer trust and financial performance.

In response, Tata Motors and JLR are stepping up safeguards across manufacturing systems, corporate IT and software driven vehicle architectures. The growing reliance on connectivity, over the air updates and cloud based services has increased exposure to cyber risk, pushing automakers globally to devote more resources to security, monitoring and incident response capabilities. Tata Group’s stance is in line with that broader trend, but the AGM remarks suggest a more explicit board level oversight of cyber readiness.

On the supply side, Chandrasekaran pointed to battery subsidiary Agratas as a cornerstone of the Group’s localisation agenda. Agratas is expected to begin production in calendar year 2027, with initial cells planned for both JLR and Tata Motors. The move is aimed at reducing dependence on imported batteries, mitigating exposure to commodity and currency swings, and tightening control over a critical input as EV volumes rise.

Localised battery supply is also central to Tata’s cost and margin ambitions in EVs. As the Group scales its electric portfolios in India and at JLR, access to competitive, in house cell capacity is expected to support more stable pricing and improved economics over time. The localisation push sits alongside efforts to deepen domestic sourcing of other key components and to diversify supply chains, as geopolitical and tariff risks reshape global flows.

The focus on cyber defence, execution risk and battery localisation, coupled with ongoing global expansion plans, signals that Tata Group’s automotive strategy is increasingly tailored to encounter challenges and be resilient even as it accelerates.
