The digital sentry for the post-quantum era
Sentry 7 PLC develops quantum-safe technology products. As quantum computing changes what today's cryptography can protect, Sentry 7 builds the tools organisations need to stay secure and trusted through the transition.
Today's cryptography has a shelf life
The next generation of digital systems requires cryptography that can withstand quantum-era threats. Sentry 7 is developing application-layer post-quantum encryption and secure communications technology for regulated enterprises and sovereign institutions.
From programme to product, we build quantum-safe technology for organisations that need to stay trusted through the post-quantum transition.
Records, communications, and data must hold up for years. We build every product for that horizon, on NIST's post-quantum standards and designed to stay verifiable as algorithms change.
Our products are being developed with Whitespace, a UK technology company that builds secure, sovereign technology for defence and national security. Whitespace brings Project HoloNet, its defence-grade messaging and encryption platform developed with IBM Quantum.
Aegis is our first post-quantum product suite, starting with Obsidian for regulated banks. Further products will follow in other sectors.
Why us?
Our advantage
Our products are built on post-quantum cryptography and run as software on the infrastructure organisations already use, with algorithms that can be rotated as standards evolve.
As an AQSE-traded company, Sentry 7 operates within a framework of transparency, regulatory clarity and strong governance. That gives customers and investors confidence in how we build and scale quantum-safe technology
Our products are shaped by the organisations that will use them. Regulated financial institutions are being invited to help shape Aegis ahead of any pilot deployment.
