Strong Validated and proven security, compliant with modern frameworks Simple Small footprint and drop-in integrations with major OEM vendors  Scalable Cloud-based, dynamic, and on-demand, with robust endpoint management Standards-based Works alongside industry standards and available in FIPS mode Strong ### We promote strong, standards-based cryptography ##### 1. Arqit's encryption keys are the most secure They aren’t vulnerable to quantum methods and are the gold standard for government and enterprise. ##### 2. Independent formal verification Arqit’s protocols have been formally validated using the Tamarin prover method by the Surrey Centre for Cyber Security and assessed by ISE. ##### 3. We address the vulnerabilities of PKI We don’t rely on public/private keys and we operate with zero-trust principles, improving upon traditional failings of PKI. ![--arqit_new_brand_general-(41)](https://arqitgroup.com/hs-fs/hubfs/Website/Website%20Imagery%202025/640%20x%20640/--arqit_new_brand_general-(41).webp?width=640&height=640&name=--arqit_new_brand_general-(41).webp) Simple ### Easy to integrate and highly performant #### We use open interfaces to allow OEM partners to upgrade their solutions easily and without a performance penalty   | | Arqit’s multi-tenanted cloud platform orchestrates agents and provides high-level management tools  | | --- | --- | | | A single-core Arqit virtual agent sits within the endpoint’s network and handles communication with the cloud | | | The vendor solution interacts with the agent only when needed using a standards-based interface |   ![--arqit_new_brand_general-(42)](https://arqitgroup.com/hs-fs/hubfs/Website/Website%20Imagery%202025/640%20x%20640/--arqit_new_brand_general-(42).webp?width=640&height=640&name=--arqit_new_brand_general-(42).webp) Scalable ### Manage large numbers of endpoints with ease Arqit’s SKA-Platform identifies, manages, and controls the interactions between endpoints with grouping and policy control ![Diagram_9](https://arqitgroup.com/hubfs/Website%20Brief%20December%2024/Diagrams/Web/Diagram_9.svg) Standards-Based ### Works alongside industry standards [![FIPS 140-3 validated product logo image in color](https://arqitgroup.com/hs-fs/hubfs/FIPS%20140-3%20validated%20product%20logo%20image%20in%20color.jpeg?width=119&height=73&name=FIPS%20140-3%20validated%20product%20logo%20image%20in%20color.jpeg)](https://arqitgroup.com/hubfs/Website%20Brief%20December%2024/Resource%20Library/Arqit%20Platform%20Standards%20Conformity.pdf?hsLang=en)     Our standards-based hybrid approach maximizes compatibility, offers cryptoagility, and minimizes risk [Arqit Platform Standards Conformity](https://arqitgroup.com/hubfs/Website%20Brief%20December%2024/Resource%20Library/Arqit%20Platform%20Standards%20Conformity.pdf?hsLang=en)   ![Diagram_10](https://arqitgroup.com/hubfs/Website%20Brief%20December%2024/Diagrams/Web/Diagram_10.svg) ## Our unique propositions Quantum-safety today through our innovative and patented approach Holistic approach most competitors focus on one postquantum method, whereas Arqit embraces many complementary methods   Doesn’t require post-quantum algorithms Arqit’s use of PQAs is limited to initial provisioning and customers can opt for symmetric-only provisioning   Strong, active authentication based on quantum-safe methods with forward secrecy that doesn’t rely on PKI   Software only  no hardware required and can run as a virtualized network function   Easy to integrate through existing OEM partner integrations, standards-based interfaces, or directly through SDK   ## Arqit’s SKA process Provisioning, authentication, and key agreement   ![Diagram_11_a](https://7543877.fs1.hubspotusercontent-na1.net/hubfs/7543877/Website%20Brief%20December%2024/Diagrams/Web/Diagram_11_a.svg) 1 Every endpoint is securely provisioned once with a “bootstrap” key ![Diagram_11_b](https://7543877.fs1.hubspotusercontent-na1.net/hubfs/7543877/Website%20Brief%20December%2024/Diagrams/Web/Diagram_11_b.svg) 2 Endpoints strongly, mutually authenticate with perfect forward secrecy ![Diagram_11_c](https://7543877.fs1.hubspotusercontent-na1.net/hubfs/7543877/Website%20Brief%20December%2024/Diagrams/Web/Diagram_11_c.svg) 3 Groups of endpoints agree quantum-safe encryption keys using material provided by Arqit SKA-Platform™ ### Talk to an Expert [Get in Touch](https://arqitgroup.com/contact-us?hsLang=en) [![Arqit_Logo_White_Citrus_Horizontal](https://7543877.fs1.hubspotusercontent-na1.net/hubfs/7543877/Website%20Brief%20December%2024/Arqit%20Logos/Arqit_Logo_White_Citrus_Horizontal.svg) ](https://arqitgroup.com/?hsLang=en) -
