Partners and Recognition

We know the problem

We’re helping to shape the way our digital world is protected against the threats of tomorrow. At a time when quantum computers will soon be able to break current cryptography methods, PQShield is focused on empowering organizations, industries, and nations, with the ultimate quantum-resistant hardware and software solutions.

Talk To Us

We set the standards

Team PQShield comprises a world-class collaboration of post-quantum cryptographers, researchers and engineers. We’ve been actively involved in the international standardization of post-quantum algorithms, and we were the first cybersecurity company to develop quantum-safe cryptography on chips, in applications, and in the cloud.

We know the priority markets

We understand the urgency. In every industry, the cryptography that keeps data, devices, connections, and components secure must be modernized to align with the new NIST global standards, and to protect our digital world.

We help our customers

Collectively, we’ve spent decades developing the research that’s led to world-class PQC solutions for the technology supply chain.

Discuss

Our team takes pride in being a clear voice of reason in a world that can so often be full of hype and jargon. We’re here to guide you through every step of the way.

Evaluate

It’s critical to know where your cryptography is at risk. We help to evaluate existing infrastructure, determining the risk and agility of the underlying architecture.

Design

We can help you to design a powerful end-to-end solution that is cryptographically secure, quantum-resilient, and compliant with all the international NIST standards.

Implement

The PQShield team has the resources, experience, and expertise to work alongside, or as part of your wider team, securely deploying end-to-end solutions.
