About Opaque Systems
OPAQUE provides a Confidential AI platform that runs AI workloads on sensitive data inside hardware-secured environments. It keeps data encrypted during processing and verifies that approved policies are enforced. The platform is deployed into the customer's own cloud, within Kubernetes clusters backed by confidential virtual machines and confidential GPUs. It requires no data migration outside that environment. The company sells to enterprises that want to use AI on regulated or proprietary data. It names high-tech, finance and insurance as industries it serves. Buyers include CISOs, compliance teams, CIOs, CTOs, AI leaders and enterprise architects. OPAQUE says its platform removes compliance obstacles by giving security teams verifiable guarantees. OPAQUE differs by offering cryptographic proof rather than assurances. Workloads are attested before execution, policies are enforced at runtime, and hardware-signed audit reports are produced afterwards. These reports can be exported and independently verified. Teams can build workflows in a visual studio or import containerised workloads, and policies can be set at data, workflow and container level.
