Sentry 7 PLC

Sentry 7 PLC is an AQSE-traded technology company developing quantum-safe products and secure communications for organisations preparing for the post-quantum era. As advances in quantum computing challenge today’s cryptography, the company focuses on helping regulated enterprises and sovereign institutions protect data, communications and digital trust over the long term.

Its work centres on application-layer post-quantum encryption, secure communications and digital integrity. Products are being developed around NIST post-quantum standards and designed to run as software on organisations’ existing infrastructure, with cryptographic algorithms that can be updated as standards evolve. Sentry 7 is developing its technology with Whitespace, a UK company focused on secure sovereign technology for defence and national security. Whitespace contributes Project HoloNet, a defence-grade messaging and encryption platform developed with IBM Quantum.

Sentry 7’s first product suite, Aegis, is planned to begin with Obsidian for regulated banks, with further products intended for other sectors. The company is also inviting regulated financial institutions to help shape Aegis ahead of potential pilot deployment.
