Cybersecurity at the Rack: The New Frontline of Data Centre Resilience

For data centre operators supporting BFSI, health-care, emergency services, and AI workloads, such disruption is not just expensive; it can be catastrophic.

India is entering a defining phase in its digital evolution. With the government accelerating plans to position the nation as a global data hub, the country's data centre footprint is expanding at an accelerated rate. According to CBRE, India's total operational data-centre (DC) capacity has recently crossed the 1.5 gigawatt (GW) threshold. That capacity boom is driven not just by legacy workloads but by the ascent of AI, cloud adoption, data localisation mandates, and surging data consumption.

With investments flowing in, CBRE tracks nearly USD 60 billion invested between 2019 and 2024 alone. Further, the firm estimates that total investment commitments will exceed USD 100 billion by 2027. This expansion is not evenly spread. A handful of cities, Mumbai, Chennai, Delhi NCR, and Bengaluru, currently account for nearly 90% of India's DC capacity. Mumbai alone holds a 53% share of the total capacity, underscoring the city's strategic importance as a digital hub, thanks to undersea cable landings and robust internet exchange infrastructure.

But this explosive growth, while critical for India's digital ambitions, brings new challenges. As demand for computing and storage surges, infrastructure complexity increases, and traditional cybersecurity playbooks, focused on firewalls, network defense, encryption, and access controls at the server layer, are no longer sufficient.

A Physical Layer That Has Become Digital

Until recently, rack-mounted components, power distribution units (PDUs), biometric locks, environmental sensors, and remote management controllers were simple, isolated, and largely analog. Their purpose was operational, not digital. Today, that has changed.

These devices now:
