NCSC selects Arqit to support UK’s post-quantum cryptography migrations

LONDON, Sept. 15, 2025 (GLOBE NEWSWIRE) -- Arqit Quantum Inc. (Nasdaq: ARQQ, ARQQW) (“Arqit”), a global leader in quantum‑safe encryption, has been selected to participate in the National Cyber Security Centre’s (NCSC) Post-Quantum Cryptography (PQC) Pilot. The pilot forms part of the Assured Cyber Security Consultancy (ACSC) Scheme, a government-led initiative to build trusted national expertise in preparing organisations for PQC migration.

As a participant, Arqit has been assured to provide Discovery and Migration Planning services to organisations preparing to migrate to quantum-safe technologies. The services will centre on Arqit’s Encryption Intelligence product, which is designed to help organisations discover, assess and manage cryptographic risk as they transition to quantum-resistant security.

Classical cryptographic algorithms that underpin today’s digital infrastructure are expected to become vulnerable to future quantum computers, threatening the confidentiality of encrypted data, authentication systems and secure communications. To mitigate this, the NCSC advises organisations to begin migration planning immediately, with cryptographic discovery and migration roadmaps in place. Priority systems should be migrated by 2030, with full migration completed by 2035.

“Post-quantum cryptography is one of the few moments in cyber history where we can act before the crisis hits,” said Andy Leaver, CEO of Arqit. “Being selected by the NCSC to participate in the PQC Pilot is a strong endorsement of our approach, using the Encryption Intelligence product to support UK organisations as they face the PQC migration challenge. This programme will help enterprises move from uncertainty to action, with clear guidance and practical tools to future-proof their security.”

Arqit’s Encryption Intelligence product is purpose-built to guide organisations through the complex process of PQC migration. It enables enterprises to map and understand their existing cryptographic assets and dependencies, assess risks across critical systems, and prioritise the areas that demand early action. By embedding cryptographic agility, Encryption Intelligence also ensures that organisations can adapt as new standards and updates emerge, providing a clear and sustainable path to quantum-safe security.

The NCSC approval follows Arqit’s acquisition of Ampliphae’s encryption risk advisory and analytics technology earlier this year, which significantly enhanced the Encryption Intelligence portfolio. This combination brings together Arqit’s quantum encryption expertise with Ampliphae’s proven visibility and analytics capabilities, enabling organisations to identify vulnerabilities, mitigate risks and build effective strategies for migrating to quantum-safe encryption.

Arqit’s participation in the pilot builds on its established work with defence, telecoms, financial services and critical national infrastructure partners. It reinforces the UK’s position as a global leader in developing practical, standards-aligned approaches to post-quantum security that can be deployed at scale.

Notes to Editors

About Arqit

Arqit Quantum Inc. (Nasdaq: ARQQ, ARQQW) supplies a unique encryption software service which makes the communications links of any networked device, cloud machine or data at rest secure against both current and future forms of attack on encryption – even from a quantum computer. Compatible with NSA CSfC Components and meeting the demands of NSA CSfC Symmetric Key Management Requirements Annexe 1.2. and RFC 8784, Arqit’s Symmetric Key Agreement Platform uses a lightweight software agent that allows end point devices to create encryption keys locally in partnership with any number of other devices. The keys are computationally secure and facilitate Zero Trust Network Access. It can create limitless volumes of keys with any group size and refresh rate and can regulate the secure entrance and exit of a device in a group. The agent is lightweight and will thus run on the smallest of end point devices. The product sits within a growing portfolio of granted patents. It also works in a standards compliant manner which does not oblige customers to make a disruptive rip and replace of their technology. In September 2024, Arqit was named as an IDC Innovator for Post-Quantum Cryptography, 2024. Arqit is winner of two GSMA Global Mobile Awards, The Best Mobile Security Solution and The CTO Choice Award for Outstanding Mobile Technology, at Mobile World Congress 2024, recognised for groundbreaking innovation at the 2023 Institution of Engineering and Technology Awards and winner of the National Cyber Awards’ Cyber Defense Product of the Year 2024 and Innovation in Cyber Award 2022, as well as the Cyber Security Awards’ Cyber Security Software Company of the Year Award 2022. Arqit is ISO 27001 Standard certified. www.arqitgroup.com
