The Future of Security is Now

End-to-end encryption is paramount in today’s business world. Phio Trusted Xchange (TX) gives organizations an affordable, crypto-agile key infrastructure to easily upgrade defenses as the threat landscape evolves. The simple overlay architecture can be dropped into any crypto environment to enable a defense-in-depth approach to your quantum readiness plans and an infinitely stronger cybersecurity posture now.

Choose the level of quantum-safe security needed based on your data inventory requirements and risk tolerance levels. Dramatically enhance your security today and be quantum-ready for the cyber attacks of tomorrow with Phio TX from Quantum Xchange.


Phio TX is the first key exchange to support quantum keys from any source (PQC, QKD, QRNG, or a combination) and unlike other quantum-safe key distribution solutions, it can deliver keys point-to-multipoint over any media that can carry TCP/IP v4 or v6 traffic, i.e., fiber, satellite, 4G, 5G, or copper.

Further crypto agility is achieved through Phio TX’s support of all PQC candidate algorithms – meaning, customers can change PQC algorithms without disturbing their networks. If desired, they can even begin with PQC then eventually add QKD with no changes needed to the underlying infrastructure.

There is no fiber required and no distance limitations on key delivery with Phio TX. Moreover, this first-of-its-kind security appliance provides FIPS 140-2 compliance that QKD alone lacks.

Phio TX extends the life of existing encryption investments by making your crypto infrastructure immediately quantum safe and crypto agile.

Phio TX leverages its patent-pending, out-of-band symmetric key delivery technology to deliver an immediate and infinitely stronger cybersecurity posture to any network environment with the highest form of encryption available. By supplementing native encryption with an additional key-encrypting-key (KEK) transmitted independent of the data path, Phio TX makes your existing encryption environment, and the data transmitted, impervious to quantum attacks and immediately more secure. This is because an attacker must now steal two keys and understand when and how they are paired – a near impossible feat.

Phio TX for Cloud

When it comes to cloud computing adoption, security remains the top priority for enterprise decision-makers. The Phio TX Cloud implementation can be used to enhance the security of PKE in the cloud by protecting transmitted data between enterprise and cloud environments with the strongest encryption available today – all while realizing the flexibility, scalability, and rapid deployment of a cloud delivery model.

Phio TX for Small Office

Still looking for quantum-safe security, but don’t have the business requirements for a mega-networked, datacenter-to-many installation? Phio TX model D provides the basic functionality found in Phio TX but for smaller engagements. This economical, scaled-down version of Phio TX offers a quantum-safe VPN – ideally suited for organizations looking to better protect remote worksites from internal and external threats with stronger, quantum-based secure communications.

Any organization deploying a network infrastructure today should ensure it is quantum-safe now or risk its premature obsolescence – a costly and risk-intense scenario best avoided!

Benefits of Phio TX

Phio TX allows users to harness the power of its patent-pending, out-of-band key delivery without having to modify the setup of the main data link. This allows users to decouple the maintenance of the encryption data channel from ability/desire to deploy other quantum-safe technologies, e.g., QRNG, QKD, PQC.

From an IT operations perspective, the user can start with a minimal number of Phio TX nodes with options to grow and improve without having to touch the data path or need to add more dedicated encrypted links — all while utilizing the same key-delivery network.

From a deployment perspective, the power of Phio TX is available in a variety of options to meet your business requirements and data protection needs today and in the future.

One of the riskiest corporate security behaviors is to not change crypto keys frequently enough. With Phio TX, the keys are changed on every transfer, adding a new level of security to your network.

Phio TX supports all PQC candidate algorithms, is FIPS 140-2 validated, and meets the ETSI protocol for QKD.

Keys can be delivered over any network media, including fiber, wireless, satellite, copper, or a combination.

Overcome the Commercial Limitations of Quantum Encryption

Quantum Xchange is the first vendor in the world to make QKD commercially viable by overcoming the technology’s previous distance and delivery limitations. While Phio TX was designed to be vendor agnostic and work independently of QKD, if desired enterprises can easily layer in QKD. Using Phio TX with QKD, point-to-multipoint transmissions with intelligent routing and out-of-band key delivery are now possible. This means Phio TX can deliver the enhanced, theoretically unbreakable security of QKD in the absence of fiber. Learn more about our Phio QK with Phio TX offering.

“After spending 20 years talking to and reviewing different computer companies for a living, I’ve got a good sense for who will or won’t be around in 10 years. Listening to Quantum Xchange’s plans and what they see as their mission (i.e. to bring quantum hybrid key distribution and networks to more of the world), I know they will become a major player.”
