Privatemode AI and Contrast

Edgeless Systems is a German cybersecurity company, whose co-founders met at Ruhr University Bochum, and which provides open-source confidential computing software. It keeps data encrypted at runtime using trusted execution environments and remote attestation.

Privatemode AI is a confidential AI inference service launched in February 2025 and extended in March 2026 with NVIDIA Confidential Computing on Blackwell GPUs. Contrast runs confidential containers on Kubernetes, and MarbleRun manages Intel SGX enclaves. Customers shown include Bosch, Capgemini and STACKIT, and the company cites work securing Germany's electronic health record system.

• Privatemode AI: confidential LLM inference with a chat app and OpenAI-compatible API.
• Multi-GPU models: runs large models across multiple GPUs including Kimi K2.5.
• Contrast: confidential containers on Kubernetes using SEV-SNP and TDX.
• MarbleRun: management of Intel SGX enclaves.
• Quantum-resistant cryptography: protection against harvest-now-decrypt-later attacks.
• Compliance pages: material for DORA, GDPR and NIS2.

• Vietnamese banks using confidential coding or document assistants on internal data.
• Hospital software vendors adding confidential transcription for clinicians.
• Government pilots of agentic AI on sensitive records within local infrastructure.

• Prompts and data stay encrypted during AI inference, including from the infrastructure provider.
• Remote attestation gives cryptographic proof of confidentiality.
• Open source supports auditability and avoids vendor lock-in.
• Available as a managed service or deployed into existing AI infrastructure.

Governments and regulated industries want to use generative AI without exposing prompts and documents to cloud operators, which drives interest in confidential AI inference. Vietnamese banks, hospitals and agencies exploring local LLM use face similar data sovereignty concerns.
