About Arqit
Arqit Quantum Inc (Nasdaq: ARQQ) secures critical data with quantum-safe encryption software. Its products integrate with existing infrastructure and require no rip and replace of hardware. Encryption Intelligence detects cryptographic exposure, identifies vulnerabilities and maps dependencies so organisations can plan PQC migration. NetworkSecure protects data in transit with post-quantum cryptography.
The approach starts with discovery. Passive analysis of live traffic at gigabit scale builds a risk-scored cryptographic inventory within weeks, so remediation is sequenced by consequence. Software-defined encryption then adds quantum-safe keys to the firewalls, VPNs and networks already in place, across IPsec, MACsec and TLS.
Arqit's customers include governments, defence organisations, critical national infrastructure and enterprises with complex cryptographic estates. Offices are in London, Belfast and Arlington, Virginia. The company is ISO 27001 accredited and Cyber Essentials certified, and Encryption Intelligence was selected for the UK NCSC's Post-Quantum Cryptography Pilot.
