HDFC Bank has announced an investment in QNu Labs, a full-stack end-to-end quantum-safe cybersecurity platform.
Founded in 2016 by Sunil Gupta, Srinivasa Rao Aluri, Mark Mathias, and Anil Prabhaka, QNu Labs focuses on building encryption and cybersecurity solutions that leverage the principles of quantum physics.
Its flagship product, QShield, is the SaaS-enabled, full-stack quantum-safe platform that protects every layer of digital infrastructure — from physical hardware to application-level systems — across endpoints, networks, edge, and cloud environments.
The company has also developed key products like Tropos (Quantum Random Number Generator), Armos (Quantum Key Distributor), and Hodos (Quantum Secure Network Layer), which are designed to protect sensitive data against quantum-enabled threats.
Arup Rakshit, Group Head, Treasury, HDFC Bank, said, “Investment in QNu gives us an opportunity to back an indigenous and future-ready innovation. By building proactive solutions in the quantum cybersecurity space, QNu Labs makes a valuable contribution to the financial sector with its quantum-safe communication networks.”
Sunil Gupta, CEO, QNu Labs, said, “We are thrilled to conclude our Series A funding with HDFC Bank as our partner. This strategic milestone validates our contrarian approach of leveraging quantum physics over classical and conventional AI-based security methods. We are not just protecting digital assets – we are working towards making India a quantum-safe nation and fortifying our digital sovereignty.”
