Quantum computing is rapidly transforming from a distant possibility into an immediate cybersecurity concern, posing a direct threat to the cryptographic systems that underpin today’s digital infrastructure.
In India, the Quantum cyber risk is amplified by an already intense threat landscape, with organizations facing thousands of cyberattacks weekly and increasing exposure to AI-driven threats that accelerate attack sophistication and scale.
Recent advancements in quantum technologies—particularly improved algorithms and reduced hardware requirements—have significantly shortened the expected timeline for disruption.
What was once considered a challenge for the 2040s is now expected within the next few years, prompting global urgency.
Industry leaders have already elevated post-quantum cryptography (PQC) to a strategic priority, emphasizing the need for immediate action.
A critical emerging threat is the “harvest now, decrypt later” strategy, where adversaries collect encrypted data today to exploit it once quantum capabilities mature.
In India’s high-risk environment, this threat is particularly concerning given widespread data exposure and evolving attack vectors.
Addressing this challenge requires more than simple upgrades.
Organizations must adopt crypto-agile strategies, combining post-quantum algorithms with existing encryption methods, while ensuring full visibility across systems.
Early action will be essential to safeguard data, maintain trust, and ensure resilience in the quantum era.
