Security built for the quantum era, not just the classical one.
PQFense designs post quantum cryptography (PQC) hardware and quantum sensing systems — including Quantum Lidar — engineered to stay trustworthy long after today's encryption stops being enough.
Data encrypted today can be decrypted tomorrow.
Adversaries are already running "harvest now, decrypt later" operations — capturing today's encrypted traffic to unlock once large-scale quantum computers arrive. Classical RSA and elliptic-curve cryptography, the backbone of nearly all current security hardware, won't survive that transition.
PQFense builds the physical layer of the answer: silicon that implements lattice-based post-quantum algorithms without leaking secrets through power or electromagnetic side channels, and sensing systems that use quantum light itself as a security and precision advantage.
Quantum hardware, sensing and security — one team.
PQFense works at the intersection of quantum hardware, quantum sensing, quantum AI and post quantum cryptography (PQC) — built against NIST post-quantum standards and India's TEC quantum technology standards.
Two product lines. One mission.
Hardened cryptographic hardware for systems that must not be compromised, and quantum sensing for the moments that must not be missed.
SCA-Resistant PQC Hardware Core
A silicon IP core running NIST post-quantum algorithms, hardened against power and electromagnetic side-channel attacks — for chips that can't afford to leak.
Quantum Lidar
Quantum-illumination-based ranging that sees through noise, fog, and jamming attempts most classical lidar can't overcome.
