All-in-One Encryption Suite for Uncompromised Application Security

Client-Side Post-Quantum Encryption

We provide high-performance, quantum-resistant and client-side encryption for your applications. This advanced encryption technology gives you a future-proof and granular Attribute-Based Access Control.

Searchable Encryption for Encrypted Databases

Findex is a unique searchable encryption service builduing indexes for you encrypted databases. Queries and result queries are encrypted, making them unreadable to third parties.

Verifiable confidential VMs

Cosmian VMs provides verifiable confidential computing on secured Intel and AMD hardware. Data and code are protected but verifiable. Even while computing. Even in the Cloud.

Customer-managed KMS

Our technology provides a cloud-external key management system, ensuring your encryption keys are secure. Your encrypted data can only be read by the intended recipient.

Data Desensitization

Your customers, partners, or suppliers can safely compute on desensitized data. Not only will you never access their data, but most notably, you can enforce & control the level of anonymization.

Discover What Makes it the Next-Generation Encryption

Our user-friendly tools empower users, developers, and data engineers to effortlessly encrypt your technical stacks. Regardless of your cryptography knowledge, our technology will help you protect your data in the post-quantum era.

Quantum-Resistant Encryption

Our encryption Suite aligns with National Cybersecurity Agency standards (NIST, ANSSI), offering organizations a future-proof, post-quantum security model, enhancing both data integrity and user trust.

Attribute-Based Access Control (ABAC)

We offer granular access control mechanisms that allow you to define and enforce who gets to access what data, ensuring that sensitive information is only available to authorized personnel.

Searchable Encryption

Don’t let your databases be vulnerable with our unique Findex technology, which allows you to build encrypted index, allowing your requests to find the correct data without decrypting your database

High-Speed Encryption

Encryption/Decryption takes about 200µs (0,0002s) for a classic ciphertext for one partition and about 400µs when post-quantum. With only 10% to 20% Ciphertext Expansion compared to cleartext size.

Enterprise-Grade Production

We deliver robust, scalable, and reliable encryption services that meet the stringent requirements of large organizations and enterprise environments.

Open-Source and Auditable

Cosmian’s commitment to open-sourced tech fosters verifiability and collaboration. Our transparent approach allows customers to inspect and verify our application code, ensuring a secure environment for all.

Turning Mathematical Excellence Into State of the Art Encryption

We work with the world’s top cryptographic experts.

We’ve collaborated with top-tier experts in cryptography and developed innovative products at the cutting edge of technology, focusing on quantum ready end-to-end encryption and secure key management.

We proudly partner with the ENS Ulm-CNRS-INRIA cryptography laboratory and the KUE Lleuven COSIC research group. Their expertise significantly enhances our work, fortifying our unwavering commitment to achieving excellence in the products you will decide to adopt, ensuring access security and privacy for all users.

And build encryption for the post-quantum natives.

As a contributor to the NIST “Migration to Post-Quantum Cryptography community of interest and the ETSI Technical Committee for Cybersecurity, Cosmian empowers you to confidently address potential vulnerabilities that may arise not only today but also in the coming decades due to advancements in quantum computing. Our technology will ensure that any of your device, app, and system’s data can’t be decrypted by third-parties, and your communications are protected, regardless of the evolving internet landscape.
