From research to real-world encrypted computing
Belfort unites experts committed to a future where knowledge is free to flow, and trust is never compromised.
In an AI-first world, trust is all you need. The future of computing is encrypted
Belfort enables that vision by accelerating encrypted compute to make it practical at scale, ensuring that sensitive data can be processed without ever being decrypted.
A spin-off from KU Leuven’s world-renowned COSIC lab, Belfort combines breakthroughs in hardware and algorithms to build the next layer of secure computing.
Performance without compromise
What once took hours now takes minutes.
Belfort brings encrypted compute within reach.
Seamless adoption
Purpose-built hardware integrates effortlessly, turning encrypted computing from concept into reality.
Security as a foundation
Data remains protected throughout every operation; confidentiality is inherent, not optional.
“For decades, we’ve explored how to make computation secure by design. With Belfort, we’re finally bringing those ideas into practice.“

Viand
Alexander Viand is a senior software developer and compiler expert, helping steer the integration between application-layer systems and hardware-accelerated kernels at Belfort. He is a top contributor to Google’s HEIR project and previously worked at Intel Labs. He combines this work with a postdoctoral position at the University of Cambridge, focusing on making advanced privacy technologies such as FHE, MPC, and ZKPs usable in practice through better systems and abstractions.
We’re building at the edge of what’s possible
Working on encrypted compute means tackling hard problems every day — in math, hardware, and systems. We don’t shy away from complexity, we lean into it together
We’re a team sport
We believe the best breakthroughs happen when cryptographers, hardware engineers, and builders work side by side. No silos, no egos, but a shared mission and a bias for collaboration.
We value speed and rigor
Our work touches national security, healthcare, and financial systems. That requires uncompromising standards, but also the agility to ship and learn fast. We balance both.
We’re in it for the long run
We know encrypted compute won’t be solved overnight. We’re building patiently, with resilience, and with a deep respect for both science and society.
We keep it real
We’re ambitious, but we don’t take ourselves too seriously. A good laugh and celebrating small wins help us keep going through the big challenges.
At Belfort, you work at the technological frontier where theory meets operation
TRUST IS ALL YOU NEED
Process data securely.
