Sells the SKA Platform, NetworkSecure and Encryption Intelligence to protect communications and assess encryption risk. Revenue combines licenses and services for telecom, government, defense and enterprise customers through a software-only model.
SKA Platform and NetworkSecure use symmetric-key cryptography to protect communications and data, while Encryption Intelligence analyzes encryption risk. Licenses and service contracts, plus professional services recognized on completion, make up the revenue model.
Customers include telecom operators, government, defense, and enterprise organizations. The workforce spans the United Kingdom and United States.
Satellite infrastructure from the former QuantumCloud offering is no longer core to the product, and the platform now runs as software only. The business depends on customer adoption and demand for more-secure encryption amid rapid technological change and product innovation.

Institutional filings for ARQQW (100% of the company) are not on file here, so the institutional figure is a floor.
