NEW DELHI/BENGALURU: Tata Consultancy Services Ltd (TCS) is piloting standardized cybersecurity practices for its largest clients, forming dedicated teams and fixed response procedures to limit damage from cyberattacks, as one of its marquee customers, Jaguar Land Rover, faces a potential $1 billion hit from a prolonged data breach. The breach halted production, exposed employee data, and has left the carmaker facing regulatory scrutiny and potential lawsuits. According to at least two executives with knowledge of the matter, India’s largest IT services firm is forming six dedicated teams, comprising about 150 people in total, to run pilots of fixed cybersecurity procedures to mitigate damage in case of a cyberattack.

Damage controlThe pilots follow a cyberattack on JLR in August that disrupted manufacturing operations and exposed personal data of employees and contractors. The breach has also caused reputational damage for the Tata Group, as TCS is handling the British carmaker’s backend IT work and both companies are part of the conglomerate. The luxury carmaker confirmed the leak of personal data to Mint and said it is engaging with affected individuals and regulators.“From the ongoing forensic investigation, JLR believes that certain data related to current and former JLR employees and contractors was affected by the cyber incident,” a spokesperson of JLR told Mint.
