Quantasphere today announced its public launch. The company builds post-quantum security products for critical infrastructure, operating in the United Kingdom and the Kingdom of Saudi Arabia.
Its first product, Tessera, is a post-quantum network encryption gateway for site-to-site WAN traffic. Tessera deploys beside existing edge routers, wraps a quantum-safe layer inside existing tunnels, and requires no rip-and-replace. Pilot deployments are live across healthcare, defense and energy.
The company also announced Aevum, a line of enterprise-grade, redundant, verifiable quantum entropy sources. Aevum is available now in three capacity tiers up to 1.6 Gbps. The datacentre-class Aevum X-Series, reaching 40 Gbps, is under development.
Quantasphere was founded in 2025 by Uzma Siddiqui, Aakif Rehman and Dr Mohammed Alshareef.
