Arqit

Arqit provides enterprise-grade quantum security solutions designed to help organisations protect data and prepare for post-quantum computing threats. Its services support the full security journey: identifying cryptographic risks, protecting networks, and demonstrating compliance. Encryption Intelligence helps organisations discover where cryptography is used, identify vulnerable protocols, build a prioritised post-quantum cryptography migration plan, and monitor their security posture over time.

For protection, Arqit’s NetworkSecure and SKA Platform provide on-demand encryption keys for VPNs, critical links, and distributed infrastructure, using a standards-aligned approach intended to work with existing systems and major equipment providers. The portfolio also includes SKA Edge Controller and SKA Central Controller solutions. Arqit highlights confidential computing, data sovereignty, secure 5G networks, and hybrid cryptography as key parts of its offering, with frequent key rotation and protection for data in use and in transit.

The company serves telecommunications, government, critical national infrastructure, and defense organisations. Its solutions are aimed particularly at customers managing long-lived sensitive data, expanding networks, or facing complex infrastructure and regulatory requirements.
