Encryption Intelligence
A cryptographic discovery and assessment platform that maps an organisation's entire encryption estate across cloud, SaaS, endpoints, networks, IoT and legacy systems. It identifies weak, obsolete or quantum-vulnerable algorithms, prioritises risk by compliance exposure, and generates migration roadmaps for transitioning to NIST-standardised post-quantum cryptography. Designed for organisations facing regulatory deadlines to migrate away from quantum-vulnerable algorithms by 2030-2035.
SKA-Platform
Arqit's key sovereignty platform that generates quantum-safe encryption keys dynamically at network endpoints using lightweight software agents. Keys are one-time use and created based on security and network policies, with no quantum hardware required. Deployed via SKA Edge Controller (hardware or cloud) or SKA Central Controller (virtualised), it supports thousands of endpoints including mobile devices and 5G base stations, and integrates with the NIST-standardised ML-KEM algorithm.
NetworkSecure
A software application that hardens VPN communications against traditional and quantum threats by integrating Arqit's quantum-safe key orchestration with existing network infrastructure. It works with firewalls and VPN technologies from Juniper, Fortinet and Cisco, supports multiple network topologies and operates across TLS, IPsec, MACsec and OTNsec layers. Particularly addresses 'Store Now, Decrypt Later' attacks where adversaries harvest encrypted traffic today for future decryption.
About
Arqit is a British cybersecurity company founded in 2017 and headquartered in London. It develops software that replaces cryptographic algorithms vulnerable to quantum computing with post-quantum encryption, targeting government agencies, defence organisations and telecoms operators.
