About
Cosmian delivers an enterprise-grade data protection suite designed for organizations moving sensitive workloads to the public cloud. At its core, the platform combines a modern Key Management System (KMS), confidential virtual machines, post-quantum encryption libraries, and a fully confidential AI runner—all purpose-built to ensure data remains secure even while in use. The Cosmian KMS provides centralized management of encryption keys, certificates, and decryption processes across the entire organization, with post-quantum resistance built in. The Cosmian VM is a verifiable confidential virtual machine that uses hardware-level security to protect code and data with cryptographic proof, removing the need to trust cloud infrastructure operators. Cosmian AI allows enterprises to deploy, query, and fine-tune AI models in complete confidentiality, with 100% encryption and no performance overhead. The advanced encryption libraries—Findex and Covercrypt—enable encrypted search and attribute-based access control policies. The suite also integrates with workplace applications like Google Workspace and Microsoft Office to protect data used with third-party SaaS tools. Cosmian is available on AWS, Azure, and Google Cloud marketplaces, making it easy for enterprises to adopt sovereign, cloud-native data protection. It is ideal for security teams, cloud architects, and enterprises handling regulated or sensitive data who need a zero-trust, verifiable security posture.
Key Features
- Modern Key Management System (KMS): Centralized management of encryption keys, decryption processes, and certificates across the organization, with post-quantum resistance built in.
- Confidential Virtual Machine: A verifiable confidential VM leveraging hardware security to protect code and data in use with cryptographic proof, ensuring no trust in cloud operators is required.
- Confidential AI Runner: Deploy, query, and fine-tune AI models with 100% encryption and complete confidentiality, ensuring AI model weights and data are never exposed.
- Post-Quantum Encryption Libraries: Findex and Covercrypt libraries provide encrypted search, post-quantum resistance, and attribute-based encrypted access policies.
- Third-Party SaaS & Workplace Encryption: Encrypt data used with external tools like Google Workspace and Microsoft Office, retaining control over what information is shared with third parties.
Use Cases
- Enterprises moving sensitive workloads to public clouds who need to maintain data sovereignty and zero-trust security without trusting the cloud provider.
- Organizations deploying or fine-tuning AI models that contain proprietary or regulated data and need full confidentiality guarantees.
- Security teams managing encryption keys and certificates across multiple cloud environments who need a centralized, post-quantum-ready KMS.
- Regulated industries (finance, healthcare, government) requiring cryptographic proof that data in use is never exposed to third-party operators.
- Businesses using Google Workspace, Microsoft Office, or third-party SaaS tools who need to encrypt data before it leaves their control.
Pros
- Sovereign & Zero-Trust Architecture: Cryptographic verifiability ensures that even cloud providers and operators cannot access your data, delivering true sovereignty.
- Post-Quantum Ready: Encryption libraries are built with post-quantum resistance, future-proofing organizations against next-generation cryptographic threats.
- Multi-Cloud Marketplace Availability: Available on AWS, Azure, and Google Cloud marketplaces, making procurement and deployment straightforward for enterprise cloud teams.
- Comprehensive Coverage: Covers the full data protection lifecycle—key management, confidential compute, AI security, SaaS encryption, and data lakes—in a single suite.
Cons
- Enterprise Complexity: The breadth of the platform and reliance on hardware-level confidential computing can make initial setup and integration complex for smaller teams.
- Primarily Paid/Enterprise Pricing: No clear free tier is advertised; the solution is geared toward enterprise budgets with cloud marketplace subscriptions.
- Niche Audience: Most valuable for organizations with strict data sovereignty, compliance, or regulated-data requirements—may be overkill for general-purpose workloads.
Frequently Asked Questions
What is Cosmian's Key Management System (KMS)?
The Cosmian KMS is a centralized application for managing encryption keys, decryption processes, and certificates across your organization. It supports post-quantum cryptographic algorithms and integrates with cloud-native environments on AWS, Azure, and Google Cloud.
How does Cosmian protect AI models?
Cosmian provides a 100% confidential AI runner that allows organizations to deploy, query, and fine-tune AI models with full encryption. Model weights and inference data remain completely confidential with no performance impact.
What is a confidential VM and why does it matter?
A confidential VM (Cosmian VM) uses hardware-level security (such as AMD SEV or Intel TDX) to protect data in use—not just at rest or in transit. Cosmian adds cryptographic verifiability so you can prove the environment hasn't been tampered with, even by the cloud provider.
Is Cosmian available on major cloud providers?
Yes, Cosmian is available on AWS, Azure, and Google Cloud marketplaces, allowing organizations to subscribe and deploy directly within their existing cloud environments.
What makes Cosmian post-quantum resistant?
Cosmian's encryption libraries (Findex and Covercrypt) are built using cryptographic algorithms designed to withstand attacks from quantum computers, ensuring long-term security for sensitive data even as quantum computing advances.
