Post-Quantum Secure Communications Platform Strategy and Product Update

Following the announcement of the Company’s proposed change of name to Sentry 7 PLC and the proposed appointment of a new Chief Executive Officer, the Company today provides further details regarding its post-quantum cryptography-based technology platform, which is intended to provide financial institutions and regulatory bodies with tools to support the integrity and verification of electronic communications in a post-quantum environment (the “Technology” or “Platform”).

Through its engineering partnership with Whitespace, as announced on 9 March 2026, the Company has continued to progress the Platform.

The Platform’s core architecture has now been defined and a detailed use case mapped against a retail bank’s end-of-day processes. In parallel, the Company and Whitespace have established a co-design programme, structured with specialist consulting and quantum security partners, through which regulated financial institutions are being invited to help shape the Platform’s requirements ahead of any pilot deployment. To date, three financial institutions have been invited to participate, one of which has confirmed its participation, with the partnership structure now being finalised.

 

Strategic Rationale and Market Position

Financial institutions are subject to regulatory requirements to retain and retrieve certain electronic communications. Existing archiving and record-keeping systems provide for the storage and retrieval of these communications. The Company believes there is an opportunity to supplement these systems with cryptographic verification of the authenticity and integrity of communications, including evidence of whether a communication has been altered following its creation.

The Company believes this is becoming increasingly relevant as organisations consider their transition to post-quantum cryptography following the publication of post-quantum cryptographic standards by NIST. The Platform’s initial focus is on secure messaging for financial institutions and regulatory bodies, with other potential applications to be considered as the Technology develops.

The Company looks forward to providing further updates as the Platform progresses through the product development lifecycle, including on its intended commercialisation strategy, potential routes to market and engagement with prospective customers and industry partners.
